 Midddle class: After feudalism came to an end in Europe, a new class of men came to the forefront of the society , the middle class.They were the trading class, the mercantile and the business class and the professionals.

Enthalpy of atomization, Δ_aH⁰, is the change in enthalpy when one mole of bonds is completely broken to obtain atoms in the gas phase. For example: atomization of methane molecule.

CH₄ (g) → C (g) + 4H (g)        Δ_aH⁰= 1665.0 kJ mol^-1

For diatomic molecules, enthalpy of atomization is equal to the enthalpy of bond dissociation. For example: atomization of dihydrogen molecule.

H₂ (g) → 2H (g);                  Δ_aH⁰= 435.0 kJ mol^-1

फ्लेमिंग का वामहस्त नियम (Fleming's left hand rule) :  

हम अपने बायां हाथ के अंगूठे , तर्जनी और मध्य उंगली को इस प्रकार फैलाते हैं  कि ये तीनों परस्पर एक दूसरे से समकोण बनाएं। तर्जनी चुंबकीय क्षेत्र को इंगित करती है । मध्य उंगली धारा के प्रवाह की दिशा को बताएगी और अंगूठा चालक पर आरोपित बल (या उसकी गति) की दिशा को ओर संकेत करेगा।

x²+ 4x + 4 = x² + 2x + 2x + 4

= x (x + 2) + 2 (x + 2)

= (x + 2) (x + 2)

x²+ 4x + 4 = x² + 2x + 2x + 4

= x (x + 2) + 2 (x + 2)

= (x + 2) (x + 2)

i. Population Control Measures

India has promoted various measures to arrest population explosion. The various population control measures include spread of awareness and knowledge of birth control measures and literacy.

ii. Use of Environment Supportive Fuel

As the fuels such as petrol and diesel emit huge amount of carbon dioxide that leads to global warming, so, the Indian government has promoted the use of CNG and LPG. These are clean, eco-friendly fuels that emit lesser smoke.

iii. Use of Solar and Wind Energy

India being a moderate country is enriched with sunlight and wind power. These are two free gifts of nature that is non-exhaustible. It solves the problem of economic growth with due focus on sustainable development.

iv. Recycling and Ban on Plastic Bags

The industrial and household wastes are accumulated on daily basis. There is a need to develop the habit of recycling of waste products in order to sustain the environment. Household waste can be used as manure for organic farming. A very recent step taken by the Indian government is banning the use of plastic bags. This is a very good step as plastic bags do not get decomposed easily and leads to pollution while recycling.

v. Pollution Tax and Fines

Indian government has taken many steps to control pollution. Some of the measures are regular vehicle checkups, levying pollution tax on the industries emitting smoke. These measures are coupled with huge fines and even imprisonment for the law breakers.

vi. Use of the Input Efficient Technology

The input efficient methods have been devised that not only increases the production and productivity but also efficiency with which the inputs are used. The efficient use of input, on one hand, leads to lesser exploitation of the natural resources and, on the other hand, enhances the future economic growth prospects of India.

The non-conventional sources of energy have many advantages. They are discussed below:

1. Cheaper and Renewable: Most of the Non-conventional Power resources are cheaper and renewable as compared to the conventional sources.

2.  Scarcity of Fossil Fuels: The overall limitation and scarcity of fossil fuels has given rise to the urgent need for exploiting alternative energy sources.

3.  Rural Energy Needs: Locally available non-conventional and renewable power resources can meet localized rural energy needs with minimum transportional cost.

4. Inexhaustible and Environment friendly: Power from Non-conventional and Renewable is a must in order to reduce carbon dioxide (CO2) emissions of the coal-based power plants. It is inexhaustible in nature and environment friendly.

The walls of the classroom had bright and colourful pictures of a horse, a goat, a parrot and a cow. They all looked familiar to Bholi and were like the ones in the village. That is why she was fascinated to see those pictures

These are the objectives of the central advisory board of physical education and recreation :

• To introduce physical education as compulsory subjects in schools.
• To suggest all the educational institutions of the country in preparing syllabus.
• To suggest the qualification for the selection process and training of the physical education teachers.
• To introduce physical education at elementary middle, high school and university level and prepare course-content accordingly.

The Role of the Board are as follows :

• The board suggests bold steps for physical education and prepares syllabus for the certificate and diploma courses to the Govt. of India.
• To suggest - different physical training methods for the boys and the girls to the centre.
• The union education ministry started scholarship in 1958 in the fields of leadership training, research etc.
• The union education ministry started giving monetary help to the organizations running programmes related to national physical efficiency test after 1958.
• Many steps were taken to run the physical education programes successfully at state level.
• Many steps were initiated to write, publish, encourage and popularise physical education.
• On board’s suggestion, the central govt. has started many programmes related to national health core in different educational institutions of India.

According to Herman Daly – a leading environmental economists the following needs should be done to acheive sustainable development:

1. Limiting the human population to a level within the carrying capacity of the environment.

2. Technological progress should be input efficient and not input consuming.

3. Renewable resources should be extracted on a sustainable basis.

4. For non-renewable resources, rate of depletion should not exceed the rate of creation of renewable substitution.

5. Inefficiencies arising from pollution should be corrected.

क्यूबा मिसाइल संकट : क्यूबा का जुड़ाव सोवियत संघ से था और सोवियत संघ उसे  तथा वित्तीय सहायता देता था। सोवियत संघ के नेता नीकिता ख्रुश्चेव ने क्यूबा को रूस के ‘सैनिक अड्डे’ वेफ रूप में बदलने का फैसला किया। 1962 में ख्रुश्चेव ने क्यूबा में परमाणु मिसाइलें तैनात कर दीं। इन हथियारों की तैनाती से पहली बार अमरीका नजदीकी निशाने की सीमा में आ गया। हथियारों की इस तैनाती के  बाद सोवियत संघ पहले की तुलना में अब अमरीका के मुख्य भू-भाग के लगभग दोगुने ठिकानों या शहरों पर हमला बोल सकता था। संघर्ष की आशंका ने पुरे विश्व को बेचैन कर दिया | दोनों महाशक्तियों के बीच परमाणुयुद्ध का खतरा मंडराने लगा था | अमेरिका ने अपने जंगी बेड़ों को आगे कर दिया ताकि क्यूबा की तरफ जाने वाले सोवियत जहाजों को रोका जाए | इन दोनो महाशक्तियों के बीच ऐसी स्थिति बन गई कि लगा कि युद्ध होकर रहेगा | इतिहास में इसी घटना को क्यूबा मिसाइल संकट के नाम से जाना जाता है |
