The correct answer is a measurement of land.

• The agricultural crops constituted the main resources which the society produced and the major part of the revenue of the state came from agriculture.
• Various types of land are mentioned in the inscriptions; land under cultivation was usually called Kshetra, Khila was the uncultivable land, Aprahata was the jungle or forest land, Gopata Sarah was the pasture land and Vasti was the habitable land.
• Different land measures were known in different regions such as Nivartana, Kulyavapa and Dronavapa.

Bierstedt regards sociology both as a Science and as an Art .

Many times Sociology is charged with what it studies, we have at least a bit of knowledge about it or we have experienced it. Sometimes in our own lives or we know it through our popular wisdom. This knowledge, while sometimes accurate, is not always reliable, because it rests on commonly held beliefs rather than systematic analysis of facts. It was once considered ‘common sense’ to accept that the earth was flat. This was questioned by Pythagoras and Aristotle. Such notions still remain with us today.

For thousands of years people’s common sense told them that big objects fall faster than small ones, that stone and iron were perfectly. Solid materials, that the desire for children is instinctive in women, that with the spread of education, the institutions of caste and dowry will automatically wither away, yet today we know that none of these statement are true. These common sense statement s based on popular wisdom illustrate our point that common sense knowledge is not always true.

Some popular observations may be true but many others are not supported by empirical data. Many .common sense conclusions are based on guesses, hunches, ignorance, prejudices, mistaken interpretation and haphazard trial and error learning. Common sense can lead us astray when we are studying other societies and also when we are studying our own society. Like other scientists, sociologists do not accept something as a fact because “everyone knows it”. Instead, each piece of information must be tested and recorded, then analysed in relationship to other data. Sociology relies on facts gathered scientifically in order to describe, understand and predict about many social phenomena. ‘

The word Environment is derived from the French word “Environ” which means all that surrounds us. 

Air Pollution: Air pollution is caused by unwanted and rejected things in the atmosphere around us. According to Oxford dictionary air pollution means “The compounds that get mixed with the atmosphere causes dangerous effects on useful plants, animals and human beings”.

Causes for Air pollution: Man’s activities in the name of the modernization have damaged the living species. Man’s activities are also responsible for polluting air, causing dirt, dust and smoke. The Natural disasters like volcanic eruption, forest fire and bacteria also cause air pollution. Man has created industries, vehicles, atomic energy, excessive use of Petrol and other source of energy like Coal, and different types of mining also cause air pollution.

Water Pollution: Water is essential for all living things 2/3 portion on the earth is covered by water, 97.2% of water on earth is mixed with solids and rest 2.8% only is left for drinking purpose.

Water pollution occurs in three different forms. 

• Inland pollution. 
• Underground pollution 
• Sea pollution.

Causes for water pollution: Water pollution is due to many factors. Factory wastes, Houses hold wastes and water from agricultural land, all these contributions to water pollution. Biological contamination like gutter water, food processing factories, skin and hide processing factories, insecticides,.drugs, various chemical colours contributes to water pollution. 

Noise Pollution Intolerable sound is considered as sound pollution, because intense sound result in physical and mental stress and also irritation. Sound pollution is also result due to various activities of human begins. Intensity of sound is measured in decibels while talking usual intensity of sound is 60 decibels.

Soil Pollution The upper most layer of the earth is consisted of “Soil” This soil layer is formed by the natural processes from millions of years. This layer supplies the necessary nutrients essential for the growth of the plants. The soil which feeds the plants is the reason for the existence of all biological system.

The decrease in the quality of the soil and changes in it due to various activities of the humans is called as soil pollution. Soil pollution lessens the productive nature of the soil and destroys the living beings in it and also its rejuvinable process.

The characteristics of social change are:

Social change is Universal and Continuous: The change is true for all societies. Whether it is east or west, urban or Rural societies, for example in rural society change may be slow in urban society change may be rapid. Today in India we find rapid change from north to south. The extent of change may be different but every part of society changes.

Social Change is Continuous and Temporal: Social change never stops. It continues and is continuous. It is also called a process. Social change happens in time period and it is called as temporal. We see in society that many innovations, alterations, modifications take place from time to time regularly. Time is the best yard stick to measure change. We observe two different phenomena in two different time period.

Social change is Inevitable: Naturally change is inevitable because it is natural. Natural phenomena are inevitable to society. Hence, social changes are inevitable. Social change does not occur according to the interest of man. Social change does not go according to our interest only. It is changing naturally. Man changes its direction and speed.

Inclusive Organisation : Society is the most inclusive organisation. As we have seen earlier, the concept Society may be analysed from both structural and functional view points. In its wider sense, it is used to refer to human race as a whole. In its narrower sence, it is applied to a tribe consisting of only few hundred people or families. The concept includes the total social heritage of folkways, mores and institutions; of habits, sentiments and ideals; also the groups in reciprocal relationships interacting upon one another.

A Report on Hazards of Overuse of Mobile Phone

Jaipur, August 17,

A recent survey done in 20 schools and at 5 busy roads of the city has revealed that 4 out of 10 students felt that their studies were adversely affected by overuse of mobile phones, 6 out of 10 vehicle driver agree that use of mobile phone while driving is dangerous and led to accidents.
No doubt, mobile phones have brought in a miraculous revolution in the field of communication. This tiny gadget is very useful for professionals and businessmen. People can be in constant and immediate contact with their loved ones and keep themselves well-informed though a number of mobile-enabled services.

However, as is true for any other thing, the overuse of mobile phone is harmful in many ways. For students, it disturbs and diverts them during their study hours at school and home. Use of social networking sites without discretion has resulted in many unpleasant and undesirable incidents, especially with girls. Use of mobile phones while driving and use of earphones while on roads or railway crossing has resulted in many injuries and deaths. Moreover, overuse of mobile phones also causes hearing problems as harmful radiations emitted by mobile phones has been found to be deadly.

जयपुर, अगस्त 7.

हाल ही में बीस विद्यालयों एवं पाँच यातायात सघन सड़कों पर किए सर्वेक्षण से ज्ञात हुआ है कि 10 में से 4 विद्यार्थियों ने अनुभव किया कि मोबाइल फोन के अत्यधिक प्रयोग से उनकी पढ़ाई पर प्रतिकूल प्रभाव पड़ रहा है। जबकि 10 में से 6 वाहन-चालकों ने यह माना कि वाहन चलाते समय मोबाइल फोन का प्रयोग खतरनाक है वे इससे दुर्घटनाएँ होती हैं।

नि:सन्देह, मोबाइल फोन ने संचार के क्षेत्र में एक चमत्कारी क्रान्ति ला दी है। यह छोटा-सा उपकरण बुद्धिजीवियों व व्यवसायियों के लिए बहुत उपयोगी है। लोग अपने प्रियजनों से निरन्तर तथा तत्काल सम्पर्क में रह सकते हैं व स्वयं को विभिन्न मोबाइल सेवाओं द्वारा भली-भाँति सूचित रख सकते हैं।

तथापि, जैसे अन्य किसी भी वस्तु के विषय में सही है, मोबाइल फोन को अत्यधिक उपयोग अनेक प्रकार से नुकसानदायक है। विद्यार्थियों के लिए मोबाइल का अत्यधिक उपयोग उन्हें उनकी पढ़ाई के समय स्कूल या घर पर उनका ध्यान भटकाता है। सामाजिक नेटवर्किंग साइट्स का बिना सोचे-समझे किया उपयोग अनेक अप्रिय व अवांछनीय परिणामों का कारण बना है, विशेषकर लड़कियों के साथ। वाहन चलाते समय मोबाइल का प्रयोग व ईयरफोन का सड़क या रेल-फाटकों पर प्रयोग अनेक घायल होने या मृत्यु होने का कारण बना है। इसके अतिरिक्त मोबाइल फोन के अत्यधिक प्रयोग से: श्रवण-समस्याएँ होती हैं तथा मोबाइल फोन से उत्सर्जित विकिरण एक जानलेवा खतरा माना। गया है।

A Report on School Tour to a Historical Monument

Kota, November 21

Our school arranged a tour of Chittorgarh for class XII students last week. Our entire class of 60 students gathered in the school grounds where the school bus waited to take us to our destination. All of us had brought their lunch and other eatables. The bus departed at 9 a.m. amid a chorus of hurrahs and shouts of joy.

Our history teaher, Mrs Sharma and our class teacher Mr Singh accompanied us. We were told not to litter and maintain discipline on the trip. The two hour journey was quite enjoyable and we reached Chittorgarh at 11 a.m.

The very first view of the Chittor Fort was stunning. The fort stood on a hilltop. Our history teacher told us that this was one of the largest forts in India and was built by the Mauryas during the 7th Century. It has also been the Capital of Mewar for more than 800 years. The fort has many gates, the main gate being Ram Pol. We saw the museum in Fateh Prakash Palace, which had a unique collection of old guns, swords and other weapons.

We also saw the famous Vijay Stambh which was built by Rana Kumbha to commemorate his victory over Mahmud Khilji. Its 157 steps lead to the top of the tower. We also saw the Rana Kumbha Palace. This palace was the residence of Meera Bai and queen Padmini. After having lunch near a large pond, we started back for Kota at 3 p.m.

It was truly a memorable experience to see history came alive before our eyes.

कोटा, नवम्बर 21

गत सप्ताह हमारे विद्यालय ने चित्तौड़गढ़ के लिए कक्षा XII के विद्यार्थियों हेतु यात्रा का प्रबन्ध किया। 60 विद्यार्थियों की सम्पूर्ण कक्षा स्कूल प्रांगण में एकत्र हुई, जहाँ स्कूल बस हमें हमारे गंतव्य को ले जाने हेतु खड़ी थी। हममें से प्रत्येक अपना दोपहर का भोजन व अन्य खाद्य पदार्थ साथ लाए थे। हुर्दे की आवाज व प्रसन्नता की चिल्लाहट के साथ बस ठीक 9 बजे प्रस्थान कर गई।

हमारी इतिहास की अध्यापिका श्रीमती शर्मा व कक्षा अध्यापक श्री सिंह हमारे साथ थे। हमें कूड़ा न फैलाने व अनुशासित रहने का आदेश दिया गया। दो घण्टे की यात्रा आनन्दायक थी व हम 11 बजे चित्तौड़गढ़ पहुँच गए।

चित्तौड़ किले का प्रथम दृश्य स्तब्ध करने वाला था। किला एक पहाड़ पर स्थित था। हमारी इतिहस की अध्यापिका ने हमें बताया कि यह भारत के विशालतम किलों में एक था। इसे मौर्यों ने सातवीं शताब्दी में बनाया था व यह 800 वर्षों तक मेवाड़ की राजधानी भी था। किले के कई द्वार थे जिनमें मुख्य द्वार राम पोल था। हमने फतेह प्रकाश महल का संग्रहालय भी देखा जहाँ पुरानी बन्दूकों, तलवारों व अन्य हथियारों का अद्भुत संग्रह था।

हमने प्रसिद्ध विजय स्तम्भ भी देखा जिसे राणा कुम्भा ने महमूद खिलजी पर विजय की स्मृति में बनवाया था। इसका 157 सीढ़ियाँ मीनार के शिखर तक ले जाती हैं। हमने राणा कुम्भा महल भी देखा। यहाँ पर मीराबाई व रानी पमिनी निवास करती थीं। एक बड़े तालाब के पास भोजन कर हम 3 बजे कोटा के लिए वापस लौटे। इतिहास को अपनी आँखों के सामने जीवन्त होते देखने का यह अविस्मरणीय अनुभव था।

The Correct Answer is Indian handicrafts were ruined.

• The Industrial Revolution in England affected India in many ways.
  • Indian textiles now had to face stiff competition from English textiles in the European and American markets.
  • Heavy duties were imposed on imported Indian textiles in Britain.
  • Farmers were forced to grow cash crops.
  • After the Industrial Revolution, Britain started producing machine-made goods and textiles that were much cheaper than Indian goods.
  • They were also often better in quality. Indian handicrafts slowly died because they could not compete against the cheaper products from Britain that were flooding the Indian markets. Hence, Option 1 is correct.

Veena asked Mohini (a) if she had been to Bharatpur. Mohini replied in affirmative and said that (b) she had been there the previous year Veena asked Mohini (C) if she knew what Bharatpur is famous for Mohini replied (d) in affirmative and further said that Bharatpur (e) is (Universal Truth के कारण is का ही प्रयोग होगा।) famous for bird sanctuary.

The Need for Morality

Every institution – be it a fanıily, a school or any other public undertaking, we find signs of discontentment, impatience and resentment. Life seems off the track in every department of life. We find better living standards around us, but lawlessness and disorder are seen everywhere. What is missing in our life?

Obviously, morality has vanished from our life. Self-introspection will make it clear that love for money has made us blind towards our family, towards our duties and towards society. We receive huge amounts of salaries and make huge profits in business but our greed for money remains unfulfilled.

Performance of duties sincerely, human sympathy, charity, mercy and helpfulness have vanished from our life. We visit the temples and listen to the preechings of the religious saints. But we never realize our moral duties because our conscience has gone dead. Let us invoke the Divine blessings and pray to Him for the revival of morality in our life

प्रत्येक संस्था चाहे वह परिवार हो, स्कूल हो या अन्य कोई जन संस्थान हो, हमें हर जगह असन्तोष, धैर्यहीनता और रोष के संकेत मिलते हैं। जीवन के प्रत्येक आयाम का जीवन पटरी से उतरा हुआ मिलता है। हम अपने चारों ओर बेहतर रहने-सहने का स्तर पाते हैं, परन्तु हर जगह कानूनहीनता और अफरातफरी देखने को मिलती है। हमारे जीवन से क्या चीज निकल गई है ?

स्पष्ट है कि हमारे जीवन से नैतिकता लुप्त हो गई है। अन्य निरीक्षण इस बात को स्पष्ट करता है कि धन के लोभ ने हमें अपने परिवार के प्रति, अपने समाज के प्रति, अपने कर्तव्यों के प्रति अंधा कर दिया है। हम मोटा वेतन प्राप्त करते हैं और कारोबार में मोटा लाभ कमाते हैं, फिर भी धन का लालच अतृप्त रहता है।

सन्यनिष्ठा से कर्तव्यों का पालन करना, मानवीय सहानुभूति, दानशीलता, दया और दूसरों के सहायता करना ये सब गुण हमारे जीवन से लुप्त हो गये हैं। हम मन्दिरों में जाते हैं, साधु-सन्तों के उपदेश सुनते हैं। परन्तु हम कभी भी अपने नैतिक कर्तव्यों को नहीं समझते क्योंकि हमारी आत्मा मर चुकी है। आओः हम दिव्य आशीर्वाद की कामना करें और प्रभू से प्रार्थना करें कि हमारे जीवन में नैतिकता पुनः जाग उठे।

√2 & – √2 both are irrational numbers. 

But √2 – √2 = 0 which is a rational number. 

Hence, sum of irrational numbers need not be irrational.

Given quadratic equation is ax² + 7x + b = 0. 

Sum of the roots of this quadratic equation is \(\frac{-7}{a}\) .

 And product of roots of the quadratic equation is \(\frac{b}{a}\) 

Given that roots of given equation are \(\frac{2}{3}\) and – 3. 

Therefore, \(\frac{2}{3} + (-3) = \frac{-7}{a}\) 

⇒ \(\frac{2-9}{3}\) =\(\frac{-7}{a}\) 

⇒ \( \frac{-7}{3} = \frac{-7}{a}⇒a=3\)  

And \(\frac{2}{3}\) × (−3) = \(\frac{b}{a}⇒\frac{b}{a}\)= –2 

⇒ b = –2a = –2 × 3 = – 6.

Hence, the value of and b are a = 3 and b = –6 .
