The colonial management of forests in Bastar and Java had the following similarities:
In Bastar the colonial government reserved 2/3 rd of the forests, put a ban on shifting cultivation, hunting and collection of forest produce. Almost the same forest management policy was there in Java. Here the villagers were not allowed for grazing cattle, transporting goods without the permit or travelling on forest roads.
In Bastar the villagers were not allowed to stay in the reserved forests and had to work free for the forest department and help them in cutting and transporting the trees. In Java also, the villagers had to pay rent on the land being cultivated initially. But later on some villages were exempted from paying rent if they provide free labour and helping the government in cutting and transporting timber.

Answer 23:
Millions of years ago all the land parts of the earth were together called Pangea. The northern landmass was called Angaraland and the southern landmass was called Gondwanaland. There was a Tethys sea in between these two land parts in which the rivers from the north and the rivers from the south were depositing sediments. Later, the peninsular plateau got separated from the gondwanaland due to the convectional currents and moved towards the north. Now the Indo- Australian plate was moving towards the much bigger Eurasian plate. This collision resulted in the rise of the sediments which were deposited in the Tethys Sea. Thus this whole process resulted in the formation of the Himalayas.

Answer 24:
Yes, it is true that population is a pivotal element in social studies.

1. It is the people who make and use the resources and are themselves as a resource.
2. It is the point of reference from which all other elements are observed and derive their significance.
3. To understand and appreciate all aspects of the environment, the number, distribution, growth and qualities are very important.
4. It is the people who develop the society and the economy.
5. Human beings are the producers and the consumers of the earth’s resource. Hence, it is important to know their number, distribution and characteristics.

Answer 25:
The food security system of India is carefully designed to ensure the availability of food to all the people at all the times. The food security system is composed of the following two components:

• Buffer stock: It is the stock of food grains like rice and wheat procured by the government through the food corporation of India (FCI). The FCI purchases rice and wheat from the areas of surplus food production at a pre- announced price called minimum support price (MSP).
• Public distribution system: This is a system of distribution of food grains among the poorer sections of the society basically those who are below poverty line. This is done through the ration shops which are also called fair price shops.

Infectious Diseases	Non-infectious Diseases
It can be transferred from an infected person to a healthy person.	It does not get transferred from an infected person to a healthy person.
They are caused by pathogens and normally spread by some agents like air, water and contact, e.g. Flu.	They are caused due to deficiency of minerals/vitamins or organ/tissue failure e.g. Kwashiorkor, Scurvy.

Answer 5.
Given mass, m = 60 g
Molar mass, M=40 g mol^-1
No. of moles, n= \(\frac { m }{ M } \) = \(\frac { 60 }{ 40 } \) = 1.5 mol

Answer 6.
Law of constant proportion states that ‘a chemical compound is always made up of the same elements combined together in the fixed proportion by mass’.

Water is composed of hydrogen and oxygen combined together in the ratio 1:8 by weight.
Atomic mass of hydrogen = 2, Atomic mass of oxygen = 16, when they combine,
∴ Ratio = \(\frac { 2 }{ 16 } \) = \(\frac { 1 }{ 8 } \) = 1 : 8
In water (H₂O) the ratio of hydrogen to oxygen is 1 : 8 in which 1 g of hydrogen and 8 g of oxygen is needed to form the compound (H₂O).
Similarly in ammonia, the ratio of nitrogen to hydrogen is 14 : 3.

Answer 7.

1. AIDS is caused by HIV virus, its full form Acquired Immuno Deficiency Syndrome.
2. It can be transmitted from an is infected person to another person by use of common syringe, through sexual contact etc.
3. Use of disposable syringes test before blood transfusion.

OR
Symbiosis is a relationship in which two organisms are associated and are mutually benefited. Lichen is an example of symbiotic life form. These life forms are found in pollution free environment, e.g. on the tree trunks, rocks, ground etc.

Answer 10.

Density	Relative Density
(i) It is defined as mass per unit volume.	(i) It is defined as the ratio of density of the substance to density of water at 4°C.
(ii) Its value is different in different systems of measurement.	(ii) Its value is the same in all systems of measurement.
(iii) Its units are g cm-3 and kg m-3.	(iii) It has no units.

Relative density of silver =10.8
Density of water = 10³ kg m^-3
∴ RD = \(\frac { Densityofsilver }{ Densityofwater } \)
Density of silver = RD × Density of water
= 10.8 × 10³ kg m^-3

Answer 11.

Radial Symmetry	Bilateral Symmerty
(i) If the body of an animal is divided into two equal parts by cutting it through any plane passing through the centre of its body, then the body of the animal is said to have radial symmetry.	(i) If the body of an animal is divided into left and right halves by only one plane, then the body of the animal is said to have bilateral symmetry.
(ii) Animals of phylum coelenterate have radially symmetrical body.	(ii) Animals of phylum helminthes and higher phyla have bilaterally symmetrical body.
E.g. Hydra, Starfish	E.g. Mammals and Birds

Answer 12.

1. Archimedes Principle: a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.
2. • A freely floating body in a fluid displaces the weight of the fluid equivalent to its own weight.
   • The centre of gravity of the freely floating body and the centre of gravity of the fluid are in the same vertical line,.
3. It is easier to swim in the sea water because it is denser than the river water and thus it can exerts more upthrust.

OR
Pascal’s law or tile principle of transmission of fluid-pressure states that “pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all the directions throughout the fluid such that the pressure ratio (initial difference) remains same”.
The tip of the pin can be easily pierced into the cloth with less pressure exerted on the smaller area for larger impact.

Camel’s feet are broad and larger area of the feet reduces the force/pressure exerted by the body on the sand. But when we have to walk on the same sand, we sink because the pressure exerted by our body is not distributed, but it is directional.

Answer 13.
Rutherford’s α-particle scattering experiment:
Fast moving α-particles were made to fall on a thin gold foil. These particles have + 2 charge and 4 u mass, and have considerable amount of energy. When they hit the gold foil the following observations are made:

• Most of the a-particles passed straight through the foil.
• Some of the a-particles were deflected by small angles through the foil.
• One out of every 20,000 particles were rebounded.

Conclusion:

1. Most of the space inside the foil is empty.
2. Positive charge of the atom occupies very less space.
3. Mass of the atom is concentrated in the centre of the atom with all positive charge concentrated in the small volume within the atom.

Answer 14.
Average atomic mass = \(\frac { 75 }{ 100 } \) × 35 + \(\frac { 25 }{ 100 } \) × 37
=26.25 + 9.25 = 35.5 u
Cobalt-60 is used to cure cancer and Iodine-123 is used for thyroid treatment.

Answer 15.
The different means by which infectious diseases spread are:

1. Through air: They are also called airborne diseases. Air carries bacteria, virus and the diseases that can be caused are common cold, influenza, tuberculosis etc.
2. Throujfn food and water: When one eats/drink contaminated food/water, that contains bacteria, virus, worms etc, it can cause diseases like cholera typhoid, hepatitis.
3. Through contact: Many diseases spread by contact of an infected person with the healthy person. Example, fungal infections, skin diseases, etc.
4. By sexual contact: Many diseases can be transmitted through sexual contact. Example, syphilis, AIDS.
5. By body fluids: Fluids like blood, semen, mother’s milk when infected can also cause diseases. Example, AIDS.
6. Vectors: The organisms that spreads diseases by carrying pathogens from one place to another are called vectors. Example, mosquitoes are vectors that carry pathogens like protozoa.

Answer 16.
(a) The rate of evaporation depends on the following factors:

1. Surface area: If the surface area is increased the rate of evaporation also increases.
   • To dry the clothes faster we spread them to dry.
   • Tea in a saucer cools faster than in a cup.
2. Temperature: If the temperature is increased the rate of evaporation also increases. Due to increase in temperature the particles gain more kinetic energy and the phase changes from liquid to gaseous phase, e.g. water will evaporate faster in the presence of sun than in shade.
3. Humidity: It is the amount of water vapour present in air. The air can hold definite amount of water vapour, at a given temperature. If the amount of water vapour is high in the air then the rate of evaporation decreases.
   On a hot and humid day, desert coolers are not effective as the air cannot hold anymore moisture to get the cooling effect.
4. Wind speed: With increase in wind speed, the rate of evaporation increases.
   The particles of water vapour moves away with the wind, thereby decreasing the amount of water vapour in the surroundings.

(b) Gases have high compressibility. This property is used in the following situations:

1. LPG (liquefied petroleum gas) is a fuel which is made up of petroleum gas. On compressing this liquified petroleum gas, it forms liquid. Similarly CNG, i.e. compressed natural gas is used as a fuel in vehicles and at home.
2. Oxygen cylinders in the hospitals have compressed gas filled in it.

Answer 17.

1. Magnetic separation
2. Centrifugation
3. Evaporation
4. Sublimation
5. Crystallisation
6. Hand picking
7. Distillation
8. Fractional distillation
9. Chromatography
10. Distillation

Answer 18.
(a) When a body moves in a circular path with uniform speed, its motion is called uniform Circular motion.

Answer 19.
(a) Activity demonstrating preparation of crystals of copper sulphate from its solution:

• Take a clean beaker (250 mL) and put the copper sulphate solution in it.
• Heat the solution in the beaker to 60 – 70° C with continuous stirring, on a wire gauze.
• Filter the solution and collect the filtrate in a china dish.
• Place the china dish over the wire gauze placed over a tripod stand and heat it gently (do not boil).
• As the solution gets heated, stir it using a glass rod. This helps in uniform evaporation and also prevents the formation of solid crust.
• When the solution is reduced to one-half of is volume, take out a drop of the concentrated solution from one end of the glass rod and cool it by blowing air. Formation of thin crust indicates that crystallisation point is achieved.
• Turn off the burner, cover the dish with a watch glass, and keep it undisturbed. As the solution cools down, crystals will separate out. Slow cooling ensures better crystallisation.
• Decant the mother liquor and wash the crystals with a thin stream of cold water and dry the crystals by pressing them gently between the sheets of filer paper.
• Blue coloured crystals of copper sulphate (CuSO₄ . 5H₂O) are formed).

Chlorination of water helps to check the growth of disease causing microbes, e.g. bateria, protozoa, etc. and it thus helps in preventing waterborne diseases. Thus, chlorination of water is important.

Answer 20.
Disease is a condition in which an individual suffers from one or more type of illness/ is not in the state of being called as healthy.
Common methods of transmission of diseases:

The common methods of transmission of diseases are:

• By air – cough, cold, tuberculosis
• By food and water – typhoid, jaundice
• By mosquito bite – malaria
• By rabid animal – rabies
• By direct contact – skin infection, small pox, AIDS
• By indirect contact – typhoid, chicken-pox

Answer 21.
Physical factors:

• Wind: When the wind blows it erodes big rocks which rub and hit with the other rocks breaking into smaller pieces which are further carried by wind to form soil.
• Sun: The heat of sun causes expansion of the rocks due to heating during daytime and it contracts at night. This expansion and contraction causes cracks in the rocks, which breaks slowly to form soil.
• Water: When it rains the force of rain water erodes the rocks which breaks to form soil.
  At times this water enters the cracks present in the rocks and freezes when temperature falls which breaks the rocks to forms soil.

Chemical factors:

• Water: Water when reacts with carbonates and phosphates present in the rocks, it form soluble compounds which make the rock hollow from inside.
• Biological factor: Living organisms also help in the formation of soil. The lichen that grows on moist surface of rocks releases certain substances that causes the rock surface to powder down and form thin layer of soil. Other small plant like moss are able to grow on this surface now.
  The roots of big trees sometimes go into cracks in the rocks and when the tree grows bigger the crack in the rocks is forced bigger.

OR
Terms involved in nitrogen-cycle are:

1. Nitrogen fixation: Plants cannot use free nitrogen present in the air. This nitrogen molecule is converted into nitrates and nitrites which can be taken up and used to make the required molecule.
   This is called nitrogen fixation which can be done by the bacteria that live in the root nodules of leguminous plants.
2. Nitrification: By physical process, i.e. during lightning, the high temperature and pressure created in the air convert nitrogen into oxides of nitrogen which dissolves in water and came down along with rain. This is also called nitrification.
3. Ammonification: The nitrogen compounds formed are taken by plants to form proteins which are further converted into ammonia.
4. Denitrification: The nitrates and nitrites of nitrogen are acted upon by other group of microbes e.g. Pseudomonas bacteria, which convert these compounds into free nitrogen gas.

Nitrogen cycle:

1. Free nitrogen from atmosphere is converted into nitrates by bacteria or by lightning.
2. Nitrates mix with soil, is absorbed by the plants to make proteins.
3. The proteins in plants and animals are converted into amino acids and ammonia.
4. Ammonia is converted into nitrates and then these nitrates and nitrites present in soil is acted upon by other group of bacteria called denitrifying bacteria. This process is called denitrification.
5. Nitrates are converted into free nitrogen and is released back to the atmosphere.

SECTION-B

Answer 22.
Weight of raisins (x) = 10 g
Weight of swollen raisins (y) = 12.5 g
The percentage of water absorbed by the raisins = \(\frac { y-x }{ x } \) × 100
= \(\frac { 12.5 – 10 }{ 10 } \) × 100 = 25%

Answer 23.
This stage is called Tumblers.
The significant characteristics are it floats on water and takes oxygen through he tube named trumpets. This is the hibernating stage.

Answer 24.

• A – seed-coat
• B – cotyledon

Answer 25.
The temperature remains unchanged until the entire solid changes into liquid even if we are heating the solid; it is because the heat is used up by the molecules in overcoming the forces of attraction between the parcticles of the solid.

Answer 26.
Suppose the dimensions of a rectangular solid is 1 then
V = 1 × 1 × 1 × (l × b × h taken as 1)
V= 1³
If it is doubled, then V = 2³
V = 8 times
Hence volume will increase by 8 times.

Answer 27.
The mixture given for separation is sand, common salt and ammonium chloride. The later two (i.e., common salt and ammonium chloride) dissolves in water. If the mixture had been dissolved in water in the first step, then the separation of these constituents would be a difficult task.

शिक्षा, शिक्षक और छात्र, तीनों का परस्पर संबंध एक-दूसरे के अस्तित्व के लिए उतना ही जरूरी है, जितना शरीर में विभिन्न अंगों का। किसी भी एक अंग में विकृति आने से संपूर्ण शैक्षणिक व्यवस्था संकटग्रस्त हो जाती है। प्राय: कई कारणों से वर्तमान शिक्षा व्यवस्था पर विद्वानों द्वारा प्रश्न उठाए जाते रहे हैं। पूर्व में भारत विद्या और शिक्षा का महत्त्वपूर्ण केंद्र था, जोकि गुरुकुल पद्धति पर आधारित था और जहाँ गुरु और शिष्य परंपरा स्वार्थ और लालच से ऊपर थी।
वर्तमान में देखें तो शिक्षा और गुरु का संबंध ग्राहक और विक्रेता की तरह बन गया है। इसका परिणाम यह हो रहा है कि शिक्षा का मौद्रीकरण होना शुरू हुआ है और अंतत: इसका दुष्परिणाम शिक्षा की गुणवत्ता के दूषित होने के रूप में दिखा है। जहाँ एक तरफ़ शैक्षणिक केंद्रों में मोल-भाव होता है और डिग्री बाँटने वाली दुकानें हर गली-मोहल्ले में खुल गई हैं, वहीं दूसरी तरफ़ परीक्षा में सफल कराने के वादों के साथ नित नए-नए कोचिंग सेंटर भी इस खेल में अपनी दुकान लगातार बढ़ा रहे हैं।
इनका परिणाम न केवल शिक्षा के स्तर को बिगाड़ने के रूप में दिख रहा है, बल्कि ये शिक्षक और छात्र के संबंधों को भी दूषित कर रहे हैं। एक शिक्षा केंद्र में पहली जरूरत शिक्षक की योग्यता होती है, जबकि वर्तमान के शिक्षा बाज़ार में यह मुद्दा भी हाशिए पर है। वैश्विक स्तर पर शिक्षा का महत्त्व प्राचीन समय से विद्यमान है। और इसके वाहक गुरु होते थे, जिनका सम्मान और आदर आमजन से लेकर राजे-महाराजे तक करते थे। ऐसा इसलिए था, क्योंकि ये शिक्षक या गुरु योग्य होते थे।

जवाब

उत्तर 1:
(क) गद्यांश में शिक्षा, शिक्षक और छात्र की तुलना शरीर के विभिन्न अंगों से की गई है। जिस प्रकार शरीर के किसी एक अंग में विकृति आ जाने से पूरे शरीर को कष्ट होता है, उसी प्रकार शिक्षा, शिक्षक और छात्र में से किसी एक में भी विकृति आ जाने से पूरी शैक्षणिक व्यवस्था ही संकट से घिर जाती है। अतः इन तीनों का परस्पर संबंध एक-दूसरे के अस्तित्व के लिए बहुत आवश्यक है।
(ख) “शिक्षा का मौद्रीकरण होना शुरू हुआ है” – इस पंक्ति का अभिप्राय यह है कि वर्तमान युग में शिक्षा को धन से तौलकर देखा जा रहा है अर्थात् शिक्षा को व्यवसाय का माध्यम बनाकर उससे केवल धनार्जन करने का प्रयास किया जा रहा है।

(ग) शिक्षा का स्तर बिगाड़ने के लिए वे लोग जिम्मेदार हैं, जो मोल-भाव करके डिग्री बाँटने वाले दुकानदार बनकर बैठे हुए हैं और परीक्षा में सफल कराने का आश्वासन देकर धन कमाने का कार्य करते हैं। उनका एकमात्र उद्देश्य केवल धन कमाना है, शिक्षा देना नहीं।

(घ) प्रस्तुत गद्यांश का उचित शीर्षक ‘शिक्षा का व्यवसायीकरण’ हो सकता है, क्योंकि संपूर्ण गद्यांश में शिक्षा के व्यावसायिक होने के कारण शिक्षक – छात्र संबंध और शिक्षा पद्धति में आए परिवर्तनों पर चर्चा की गई है।

उत्तर 2:
(क) प्रस्तुत काव्यांश में महाराणा प्रताप के घोड़े चेतक की बहादुरी का वर्णन किया गया है। उसकी विशेषता यह है कि वह हवा से भी अधिक तीव्र गति से दौड़ता है।
(ख) राणा प्रताप के घोड़े चेतक को कोड़ा इसलिए नहीं मारना पड़ता था, क्योंकि वह अपने कार्य में कुशल था अर्थात् कोड़ा मारने से पहले ही वह तीव्र गति से दौड़ने लगता था।
(ग) शब्द                                 समानार्थक शब्द
(i) अरि                     –         शत्रु, दुश्मन, बैरी, रिपु

उत्तर 7:
(क) दुःख, आश्चर्य, हर्ष, घृणा आदि मनोभावों को प्रकट करने के लिए विस्मयादिबोधक चिह्न का प्रयोग किया जाता है।
(ख) ‘हिंदू-मुसलमान’ में योजक चिह्न (-) का प्रयोग हुआ है। योजक चिह्न का प्रयोग समस्त पद के खंडों को जोड़ने के लिए उनके मध्य में किया जाता है; जैसे-हिंदू-मुसलमान आदि।
(ग) किसी बड़े शब्द को छोटा लिखने के लिए उसके प्रथम अक्षर को लिखकर उसके आगे (०) शून्य लगा दिया जाता है, वहाँ लाघव चिह्न होता है; जैसे- ‘डॉ.’ शब्द में लाघव चिह्न है, इसका पूर्ण रूप डॉक्टर है।

उत्तर 8:
(क) भगवाना तेईस वर्ष का जवान युवक था। वह प्रतिदिन खरबूजों की डलिया बाज़ार में पहुँचाता था। एक दिन वह प्रातःकाल खेत से पके हुए खरबूजे तलाश कर रहा था। वह बेल में लगे खरबूजे चुनने के बाद कुछ देर विश्राम करने के लिए गीली मेड़ के पास पहुँचा, तो उसका पैर एक साँप पर पड़ गया और साँप ने उसे डस लिया, जिससे उसकी मृत्यु हो गई।
(ख) लेखक ने महादेव जी की सज्जनता व सहृदयता की तुलना | बिहार और उत्तर प्रदेश के हज़ारों मील लंबे समतल मैदानों से की है, क्योंकि वहाँ न तो खुरदरी मिट्टी है और न ही कंकरी।
(ग) कलाभिज्ञ लोग अर्थात् कलाकार, चित्रकार, मूर्तिकार, छायाकार (फोटोग्राफर) आदि कीचड़ जैसा रंग पसंद करते हैं।’

उत्तर 9:
रात में लगभग साढ़े बारह बजे थे तथा लेखिका गहरी नींद में थी। अचानक लेखिका के सिर के पीछे कोई भारी व कठोर वस्तु टकराई और ज़ोर से आवाज़ हुई।

लेखिका नींद से जाग गई, उसे साँस लेने में परेशानी होने लगी। उसने देखा कि एक विशाल बर्फ का हिमखंड टूटकर उसके तंबू पर गिर गया है। वह लंबा बर्फ़ का पिंड लेखिका के कैंप के ठीक ऊपर ल्होत्से ग्लेशियर से टूटकर नीचे गिरा था। उस विशाल बर्फ पुंज ने एक्सप्रेस रेलगाड़ी की गति से आते हुए तथा भीषण गर्जना करते हुए सारे कैंप को तहस-नहस कर दिया था। लगभग प्रत्येक व्यक्ति को चोट लगी थी और लेखिका हो। बर्फ में दब ही गई थी, परंतु अच्छी बात यह थी कि किसी की मृत्यु नहीं हुई थी।

अथवा

‘तुम कब जाओगे, अतिथि’ पाठ में लेखक और उसकी पत्नी भारतीय परंपरा के अनुसार, अतिथि का बढ़-चढ़कर स्वागत-सत्कार करते हैं। उन्हें लगता है कि अतिथि सम्मान-सत्कार की स्मृतियाँ लेकर अगले दिन लौट जाएगा, लेकिन अतिथि तो जाने के लिए तैयार ही नहीं था। आज की महँगाई के समय में सीमित आय वाले लोग अधिक दिनों तक अतिथि का स्वागत-सत्कार नहीं कर सकते। लेखक ने अनेक प्रकार के उदाहरणों, कार्यों द्वारा अतिथि को चले जाने का संकेत दिया था, फिर भी अतिथि पर कोई प्रभाव नहीं पड़ा। लेखक के घर उपवास रखने की स्थिति उत्पन्न होने लगी थी। प्रेम संबंधों में मतभेद उत्पन्न होने लगे थे। अतिथि लेखक को मानव नहीं, राक्षस का प्रतिरूप दिखने लगा था। अब केवल एक ही उपाय बचा था कि लेखक भी सभ्यता का आवरण उतारकर अतिथि को सीधे जाने के लिए कह दे।।

उत्तर 10:
(क) कवि ने ईश्वर को सर्वगुण संपन्न बताते हुए स्वयं को ईश्वर का अंश माना है। ईश्वर के साथ अपनी एकात्मकता को अनेक रूपों में व्यक्त करते हुए रैदास कहते हैं कि प्रभु चंदन हैं, तो वह पानी, प्रभु बादल हैं, तो वह मोर, प्रभु दीपक हैं, तो वह । बाती, प्रभु मोती हैं, तो वह धागा, प्रभु चाँद हैं, तो वह चकोर। इस प्रकार दोनों का मिलन सोने एवं सुहागे के मिलन जैसा पवित्र एवं महत्त्वपूर्ण है। वास्तव में, दोनों में अभिन्न संबंध है।

(ख) ‘मोती’ के संदर्भ में ‘पानी’ का अर्थ है-चमक रहीम का कहना है कि चमक के बिना मोती का कोई मूल्य नहीं होता है।
‘मानुष’ के संदर्भ में ‘पानी’ का अर्थ है-आत्म-सम्मान। रहीम का कथन है कि आत्म-सम्मान के बिना मनुष्य का कोई मूल्य नहीं होता है।
‘चुन’ के संदर्भ में पानी का महत्त्व सर्वोपरि है। बिना पानी के आटे की रोटी नहीं बनाई जा सकती। इसलिए वहाँ पानी का । होना अनिवार्य है।

(ग) कविता में समय की कमी की ओर इशारा इसलिए किया गया है, क्योंकि लोगों की स्वयं में अत्यधिक व्यस्तता ने एक दूसरे के प्रति उनके भीतर की आत्मीयता को समाप्त कर दिया है।

उत्तर 11:
‘आदमीनामा’ कविता के रचयिता कवि नज़ीर अकबराबादी अपनी कविता के माध्यम से कहना चाहते हैं कि आदमी की प्रवृत्तियाँ भिन्न-भिन्न हैं। वह धन-संपदा का स्वामी बनना चाहता है। धनवान, भोगी एवं राजा बनना चाहता है। वह सद्गुरु बनकर लोगों को उपदेश देना चाहता है। वह दुनिया में अत्यधिक सम्मान प्राप्त करना चाहता है। वह करुणामय भी है तथा दूसरों की सहायता के लिए अपने प्राणों की बाज़ी भी लगा देता है।
वह दीन-दुःखियों की सहायता करना चाहता है। वह धार्मिक भी है और मानवता की सेवा करना चाहता है, लेकिन इन सबके साथ-साथ वह स्वार्थी भी होता है। वह अपने स्वार्थ के कारण दूसरों को कष्ट भी पहुँचाता है। वह चोरी भी करता है और हिंसा में भी लिप्त रहता है। अपने लाभ के लिए वह दूसरों की जान तक ले लेता है। वह दूसरों को अपमानित भी करता है। और उनसे लड़ता-झगड़ता भी है। इस प्रकार आदमी के अंदर दोनों प्रकार की विपरीत प्रवृत्तियाँ देखने को मिलती हैं।

अथवा
भक्तों के व्यवहार से आहत होकर सुखिया के पिता ने उन्हें दुष्ट कहकर संबोधित किया। सुखिया का पिता अपनी पुत्री की अंतिम इच्छानुसार देवी के मंदिर से पूजा का फूल लेने आया था। मंदिर में भक्तों द्वारा उसे पहचान लिया जाता है कि वह अछूत है। सभी ने मिलकर उसे बुरी तरह पीटा जिस पर वह कहता है कि मेरे मंदिर में प्रवेश करने से तुम्हारी देवी की । महानता कैसे कम हो गई? क्या मेरी कलुषता उनके गौरव की अपेक्षा अधिक है? दुष्ट भक्तों! तुम ऐसा तुच्छ विचार करके भी स्वयं को माँ का भक्त कहते हो। देवी माँ किसी को छूत-अछूत नहीं मानती। उनकी दृष्टि में सभी समान हैं।
अतः कहा जा सकता है कि समाज में व्याप्त सामाजिक अस्पृश्यता ने समाज में मानवीय संवेदनाओं को नष्ट कर दिया। है। इसी कुरीति के कारण पिता अपनी पुत्री सुखिया को खो बैठता है।

उत्तर 12:
महिसागर नदी के दोनों किनारों पर उत्साहपूर्ण वातावरण था। हज़ारों लोग सत्याग्रहियों के स्वागत में खड़े थे। उन लोगों के हाथों में जलते दीये जागृति के स्वतः प्रमाण थे। ऐसा लग रहा। था जैसे सभी गांधी और पटेल के नेतृत्व में देश के सपनों को पूरा करने के लिए पूर्णतः तत्पर हैं। नदी के दोनों तटों पर लोगों द्वारा लगाए जाने वाले ‘महात्मा गांधी की जय’, ‘सरदार पटेल की जय’ और ‘जवाहरलाल नेहरू की जय’ के नारे गूंज रहे थे। लोग स्वराज प्राप्ति के लिए सजग, उत्साहित और कटिबद्ध थे। महिसागर नदी के दोनों किनारों पर लगी लोगों की भारी भीड़ स्पष्ट रूप से यह दर्शा रही थी कि लोग पूर्ण समर्पण एवं निःस्वार्थ भावना से अपने देश को प्रेम करते हैं तथा उसके लिए कुछ भी करने को तैयार हैं। लोगों ने वहाँ व्याप्त अँधेरे को भेदने के लिए अपने हज़ारों हाथों में हज़ारों दीये जलाए, ताकि दोनों ओर के लोग नदी पार कर सकें।।
उन्होंने प्रत्येक कदम पर गांधीजी एवं उनके सत्याग्रही साथियों की सहायता करने का प्रयास किया। राष्ट्र एवं राष्ट्र के सेवकों के प्रति उनके निःस्वार्थ समर्पण की भावना उनकी प्रत्येक गतिविधि से झलक रही थी।

अथवा
हामिद खाँ के अनुसार, पाकिस्तान में हिंदू-मुसलमानों के मध्य अच्छे संबंध नहीं थे। वहाँ दोनों संप्रदायों के बीच धार्मिक विषमता बहुत अधिक थी। हिंदुओं द्वारा मुसलमानों को अत्याचार करने वालों की संतान समझा जाता था। पाकिस्तान में हिंदू-मुस्लिम एक-दूसरे के त्योहारों में सम्मिलित नहीं होते। वहाँ न कोई हिंदू, मुस्लिम होटल में खाना खाता है और न ही कोई मुस्लिम, हिंदू दुकान पर जाता है। इस दुनिया में उन्हें शैतानों की भाँति छुप-छुप कर चलना पड़ता था। अतः हामिद खाँ के अनुसार दोनों समुदायों में यह अंतर बहुत अधिक था। किसी भी जाति, धर्म, समुदाय या नस्ल के मनुष्यों के बीच भेदभाव करना, असमानता स्थापित करना  ईश्वरीय इच्छा के विपरीत है।
ईश्वर ने सभी मनुष्यों को एक समान बनाया है. हमने उनमें विभाजन उत्पन्न किया है। सभी मनुष्य एक ही ईश्वर की संतान हैं। अतः उनके बीच किसी भी प्रकार का भेदभाव किया जाना, किसी भी प्रकार से उचित नहीं हो सकता है।

उत्तर 13.1:
देश के नागरिकों को बिना किसी जातीय, सांप्रदायिक वनस्लीय भेदभाव के एक साथ रहना ही राष्ट्रीय एकता है। यह किसी भी राष्ट्र की एक प्रबल शक्ति होती है। यह वीरता और बलिदान संबंधी कार्यों को भी प्रेरित करती है। यह जनता में आत्मविश्वास की भावना उत्पन्न करती है, जिससे देशवासी उन्नति के पथ पर आगे बढ़ते हैं।
विश्व स्तर पर देखें, तो स्पष्ट हो जाएगा कि राष्ट्रीय एकता के बिना किसी राष्ट्र का विकास के पथ पर अग्रसर होना अत्यंत चुनौतीपूर्ण हो जाता है। राष्ट्रीय एकता में ही राष्ट्र की सारी शक्तियाँ केंद्रित होती हैं और एक शक्ति-स्रोत का जन्म होता है।
वर्तमान समय में अनेक नकारात्मक और उन्मादी सोच वाले व्यक्ति या समूह भारतवर्ष की एकता खंडित करने के लिए प्रयासरत हैं। आज आवश्यकता इस बात की है कि निजी हित और अलगाववादी तत्त्वों को पूरी दृढ़ता से नकार कर हम राष्ट्र को एकता की मज़बूती से बाँधकर रखें, क्योंकि राष्ट्रीय एकता पर ही राष्ट्र की अखंडता निर्भर करती है।

उत्तर 13.2:
मेरे प्रिय कवि हिंदी के भक्तिकालीन संत कवि कबीर हैं। कबीर का संतुलित एवं विशिष्ट व्यक्तित्व तथा उनके विचारों ने मुझे सदैव प्रभावित किया है। वे ईश्वर के सजग भक्त थे। गुरु, ज्ञान, कर्म, धर्म और अध्यात्म की उन्होंने सच्ची विवेचना की है। वे जो स्वयं करते थे, वही अपने अनुयायियों से भी अपेक्षा रखते थे। उनके व्यक्तित्व में मन, वचन और कर्म की एकता परिलक्षित होती है। कबीर के दोहे या पद स्वयं में सामाजिक परिवर्तन के सकारात्मक उद्देश्यों को समेटे हुए हैं। उन्होंने समाज में फैली कुरीतियों; जैसे-जात-पाँत, छुआछूत, ऊँच-नीच आदि पर तीक्ष्ण प्रहार किया है। कबीरदास पुस्तकीय ज्ञान को महत्त्व न देकर अनुभव आधारित ज्ञान को महत्त्व देते थे। उन्होंने सदा सत्य का साथ दिया है, इसलिए वह सभी के लिए लोकप्रिय कवि बन गए हैं। उनकी विशेषता यह है कि वे संत होकर भी क्रांतिदर्शी थे। उनकी भक्ति अंधभक्ति या पाखंडपूर्ण नहीं थी। कबीर के पदों में सामान्य बोलचाल की भाषा का प्रयोग देखने को मिलता है, जो जनमानस को सीधे इनसे जोड़ता है। वास्तव में, कबीर एक प्रकाश पुंज थे, जिन्होंने एक विशाल समाज का पथ आलोकित किया।

उत्तर 13.3:
स्वस्थ शरीर में ही स्वस्थ मस्तिष्क निवास करता है। खेल, शरीर को स्वस्थ रखने के लिए अत्यंत आवश्यक है। यद्यपि खेल के प्रति लोगों की प्राचीन धारणा यह थी कि इससे समय और धन की बर्बादी होती है, परंतु वर्तमान समय में खेल के माध्यम से सफलता के शिखर पर पहुँचने वालों ने इस मिथक को ध्वस्त कर दिया है। खेल व्यक्ति को शारीरिक और मानसिक दोनों स्तर पर स्वस्थ रखने का उत्तम साधन है, इसलिए खेल का जीवन में अत्यंत महत्त्वपूर्ण स्थान है। यही कारण है कि विद्यालयों में खेल को एक विषय के रूप में स्थान दिया गया है। खेलने वाला व्यक्ति जीवन में विभिन्न स्पर्धाओं का सामना करने में अत्यंत सक्षम होता है। वह हारकर भी जीतने का साहस रखता है, साथ ही प्रतिद्वंद्वी की सफलता की सराहना भी करता है। खेल हमारे व्यक्तित्व को निखारता है। आज यह आर्थिक, सामाजिक, स्वास्थ्य, राष्ट्रीय आदि अनेक पक्षों से संबद्ध होकर अपनी सार्थक महत्ता सिद्ध कर रहा है।

प्रिय मित्र अंकिता,
आशा है कि तुम्हारी पढ़ाई ठीक प्रकार से चल रही होगी और तुम मन लगाकर परीक्षा की तैयारी में लगी होगी। तुम्हें यह जानकर खुशी होगी कि हमारे विद्यालय ने प्रधानमंत्री द्वारा चलाए गए ‘स्वच्छ भारत अभियान’ से जुड़ने का निश्चय किया है। विद्यालय के सभी छात्र-छात्राएँ अपने-अपने क्षेत्रों में स्वच्छता अभियान से जुड़ेंगे। वे प्रत्येक रविवार को विभिन्न स्थानों पर अपने अध्यापकों के मार्गदर्शन में समूह बनाकर स्वच्छता का कार्य करेंगे। मैं चाहती हूँ कि तुम भी अपने विद्यालय के सहपाठियों तथा अध्यापकों से इस संबंध में बातचीत करो और अपने अन्य मित्रों को भी इस कार्य में सहयोगी बनने के लिए प्रेरित करो। तुम जानती ही हो कि स्वच्छता के विषय में हमारा देश बहुत पीछे है, यदि हम अपने आस-पास के वातावरण को गंदगी से मुक्त रखेंगे तथा स्वच्छ बनाएँगे, तो यह बहुत महत्त्वपूर्ण कदम होगा।

मुझे पूरी आशा है कि तुम स्वच्छ भारत अभियान से जुड़कर भारत को स्वच्छ बनाने में अपना पूरा सहयोग दोगी।

प्रिय मित्र राज,
मैं यहाँ सपरिवार कुशलपूर्वक हूँ तथा कामना करता हूँ कि तुम भी सकुशल होंगे। शायद तुम्हें स्मरण होगा कि दो माह पूर्व तुमने मुझसे हिंदी की ‘गुनाहों का देवता’ नामक पुस्तक ली थी और 15 दिनों में पढ़कर लौटाने का वादा किया था, परंतु आज दो माह बाद भी, अनेक बार आग्रह करने के पश्चात् भी तुमने यह पुस्तक मुझे नहीं लौटाई है।
मित्र, इस प्रकार की बहानेबाज़ी सदैव नहीं चल सकती। अब मुझे शंका होने लगी है कि कहीं लापरवाही के कारण तुमने यह पुस्तक गुम तो नहीं कर दी है? इस प्रकार की लापरवाही व चुप्पी हमारी मित्रता में दरार का कारण भी बन सकती है। मेरा पुनः एवं अंतिम अनुरोध है कि तुम यह पुस्तक यथाशीघ्र मुझे वापस कर दो। मुझे आशा है कि तुम मुझे निराश नहीं करोगे। तुम्हारा मित्र राजन

2. We can prevent exposure to airborne microbes by providing living conditions that are not overcrowded. Exposure to waterborne microbes can be prevented by providing safe . drinking water. This can be done by proper scientific way of treating the water to kill any microbial contamination. Exposure to vector-borne microbes can be prevented by living in a clean environment.

Answer 10.
Pressure is defined as thrust per unit area (or force acting per unit area). Its SI unit is Pascal, (Pa)
m = 30 kg
A = 20 cm × 15 cm = 300 cm²
= 0.03 m²
g = 10 m/s²
p = \(\frac { mg }{ V }\) = \(\frac { 30\times 10 }{ 0.03 }\)
= 10⁴ Pa

Answer 11.
Law of conservation of momentum: The sum of the momenta of the two objects before collision is equal to the sun of the momenta after collision, provided there is no external unbalanced force acting on them.
When a person falls on the hard floor, he is brought to rest in a very short interval of time, so a greater force come into play.
On the other hand when he falls on a heap of sand, he is brought to rest in a longer time, so lesser force come into play/explanation in terms of momentum.

Total momentum before firing (pistol & bullet) = 0
Total momentum after firing (of pistol & bullet) is
= 0.02 kg × ( 100 m s^-1) + 1.5 kg × v ms^-1
= (2 + 1.5 v) kg ms^-1
Total momenta after firing = total momenta before firing
2 + 1.5 v = 0
1.5 v = -2
∴ v = 1.33 m/s

Answer 14.
Let the mass of AgNO₃ used be x.
Then, mass of NaNO₃ formed will be \(\frac { x }{ 2 }\)
Mass of reactants = Mass of products
x + 5 = 8.1 + \(\frac { x }{ 2 }\)
\(\frac { x }{ 2 }\) = 3.1
x = 6.10 g
Mass of AgNO₃ Used = 6.10 g
Mass of NaNO₃ formed = \(\frac { 6.10 }{ 2 }\) = 3.05 g

Answer 15.

1. If absorbent materials are absent then there will be multiple echoes, due to which sound cannot be heard clearly.
2. Sound waves are mechanical waves and cannot travel through vaccum.

Answer 16.

Answer 17.

(a) Outer Ear: Pinna, auditory canal and tymphanic membrane.

• Pinna – It collects the sound from the surroundings.
• Auditory Canal – The sound waves collected pass through this canal.
• Tymphanic Membrane – It is a thin membrane which receives the vibrations of sound. A compression reaches the ear drum, the pressure on the outside of the membrane increases and pushes the ear drum inwards, and moves out when the rarefaction reaches the ear drum.

(b) Middle Ear: Consists of three small bones called hammer, anvil and stirrup. The vibrations are received by these three bones and the strength of vibrations is increased i.e., the sound is amplified and passed to inner ear.
(c) Inner Ear: It consist of cochlea and auditory nerve. Cochlea receives the amplified vibrations and convert them into electrical signals. These electrical signals are sent to the brain via the auditory nerve and brain interprets the signals as sound.

Answer 18.
Work is said to be done when the force applied on an object moves it in its own direction.
Example of negative work done – When a body is sliding on a surface, work done by force of friction is negative.

Answer 19.

1. Buoyant force = Weight of liquid displaced
   = (Volume of the liquid displaced) × (Density of liquid) × (Acceleration due to gravity)
   So, density of liquid and volume of the liquid displaced affects the buoyant force.
2. Buoyant force exerted by liquid does not depend upon its volume.
   So, the buoyant force will not increase on increasing the volume of the liquid.
3. Hydrometer and lactometer are based on Archimedes’ principle. Submarines are also designed according to Archimedes’ principle.

Answer 20.
Three different cropping patterns, namely mixed cropping, inter-cropping and crop-rotation are generally practised.
1. Mixed cropping allows two or more crops to be owed simultaneously on the same piece of land. Wheat and gram, wheat and mustard, groundnut and sunflower etc. are some common examples of crops grown through mixed cropping. Crops are chosen in such a way that they require different amounts of minerals.

2. Inter-cropping allows farmers to grow two or more crops simultaneously in the same field in a definite pattern. For example, cauliflower and chilli plants are grown together in alternating rows on a single field. To ensure that maximum utilisation of the nutrients applied, crops are selected in such a way that their nutrient requirements are different. Other examples of crops grown through inter-cropping include soyabean and maize, finger millet (bajra) and cow-pea (lobia) etc.

3. Crop-rotation is the practice of growing two or more varieties of crops in the same field in sequential seasons. A common example of crop-rotation is to cultivate maize followed . by soyabean. This system helps in protecting crops from pests and diseases. The crops selected, vary in nutrient requirements. This ensures complete and uniform utilisation of the nutrients applied.
