Define ionic mobility. Write its relationship with relaxation time. How does one understand the temperature dependence of resistivity of a semiconductor? |
|
Answer» Mobility of an ion is defined as the drift velocity per unit electric field i.e., μ = vd/E = eτ /m Its unit is m2 /Vs. When temperature increases, covalent bonds of neighbouring atoms break and charge carrier become free to cause conductive, so resistivity of semi conductor decreases with rise of temperature. |

A little guy in a bowler hat, a close-fitting jacket, a cane, oversized shoes and a brush-like moustache! 2. Before long, Chaplin found himself a star. That puzzled him, for he saw himself essentially as a shy British Music hall comedian. The U.S. acknowledged him as its king of silent film comedy. Soon, so did crowds all over the world. 3. But life wasn't always a laugh for Charles Spencer Chaplin. Both his parents were Music Hall artists, who separated when Charlie was very young. His childhood was very sad, for his mother never earned enough to look after Charlie and his elder brother, Sydney. Sometimes, Chaplin had to sleep on the streets and forage for food in the garbage. 4. Charlie took his first bow on stage when his mother made her last appearance. It happened when her voice broke during a song. Her son stepped on stage and sang a popular song. That's when a star was born. 5. Through all these years of success, Charlie never forgot his troubled childhood. It made him recall a Christmas when he was denied two oranges and his bag of sweets for breaking a rule at the orphanage he went to after his mother's death. It would have broken his heart, if the other children had not offered him a share of theirs. Spontaneously, the adult Chaplin gifted the orphanage with a motion picture machine and insisted that each child should have as many oranges and sweets as they pleased.Answer the following : (a) To search for food (para 3) (b) Created (para 1) (c) Opposite of 'failure' ?

Kush read the following article in The Economic Times : An Urban Farm in an Urban Jungle Can you create functional, green spaces in a crowded city like Mumbai ? ‘Fresh and Local’ is an initiative to transform under used spaces into productive, community areas through urban farming. It aims to inspire city residents to make the most use of the spaces that surround them to grow fruits, herbs and vegetables. Not only can urban farming improve the environment, but it can also improve the health of the city residents. Kush decides to write a letter to the editor of a national daily to raise public awareness about using the space around them for productive community areas. Use your ideas and ideas from the unit ‘Environment’ to write a letter in about 100-120 words. |

Answer» 18 Model Town Mumbai 14th May, 20×× The Editor The Times of India Mumbai Subject : Steps to Improve the Environment Sir Through the columns of your esteemed newspaper, I wish to draw the attention of the general public towards the underused spaces in crowded cities like Mumbai. These spaces can be best used by taking some initiative to make them green. We can grow fruits, vegetables and herbs which will help in the improvement of the environment as well as in the improvement of the health of the city residents. Urban farming should not be taken as a Herculean task. It is only a matter of the effort taken to transform these areas/spaces into productive, community areas. Thus, people will be able to breathe and live in a pollution–free environment which is good for health. Conservation of soil and more of greenery will be an added advantage. I hope, that people will become aware of these underused spaces and will take some action after reading this letter of mine. Thanking you Yours sincerely Kush |

The pie-chart given below shows the changing trends in the recreational activities of children of two different generations. You are disturbed at very little importance being given to book reading, followed by sports and games which are mostly indoors resulting in poor health and stamina. You decide to write a letter to the editor of ‘The Herald Tribune’, New Delhi on this issue, suggesting ways and means to improve the condition. Sign yourself as Malavika/Manas, a Health Specialist from New Delhi and write a letter in about 120 words. |
|
Answer» Deptt. of Health Care New Delhi 14th April 20×× The Editor The Herald Tribune New Delhi Subject : Changing Trend in Children’s Activities Sir Through the columns of your esteemed newspaper, I wish to draw the attention of the public towards the changing trends in the recreational activities of children in modern times. It is shocking to know that present day children don’t want to spend their leisure hours in book-reading, sports and games or any other outdoor activities as was done in the years from 1960-1980. Rather, modern day juveniles are more interested in indoor activities. Only 10% of them are interested in book reading whereas, 60% can be seen busy with gadgets. This is not a positive trend. It is leading our children towards poor health and stamina. In my opinion, children should be made to understand the importance of reading books and this can be done at the school level as well as by parental interference. The advantages of outdoor games must be stressed upon. They must realise that outdoor games impart to them the value of discipline as well as team spirit. Parents should not provide them with electronic gadgets at an early stage. I hope this letter of mine will spread awareness among children as well as parents and that the recreational activities of children will again get channelized in a positive way. Thanking you Yours sincerely Malavika (Health Specialist) |

Read the following passage carefully.Motivations for ruralism in underdeveloped countries are understandably different from those in developed countries. There, it is a sheer physical necessity for the very act of man’s survival. In the third world countries, which are predominantly rural, the only level that can lift human life above its present sub-human level, is rural development. Rural life in such countries has been stagnating for centuries on end. Nothing worthwhile has been done to ameliorate the condition of the rural population, which is only slightly different from that of their quadruped counterparts. Ignorance, ill health and poverty have become synonymous with rural life in the undeveloped and underdeveloped countries. But the worst tragedy is that the concerned human populations have taken this state of affairs for granted, as something unalterable, something for which there is no remedy. Every ray of hope has gone out of their lives. In such countries, Rural Development is the inevitable condition of any material or non material advancement. As such, enlightened sections of all such countries have been taking an ever growing interest in the question of Rural Development. This was also part of the legacy of their freedom struggle. In countries like India, it is well-known that attempts at Rural Development were an inseparable part of the Independence Movement. Leaders like Gandhiji realized quite well that Real India lived in her stagnating villages. Cities, which were mostly the products of western colonialism, were just artificial show pieces. Even then, there were two worlds. The posh areas, where the affluent few, mostly the products and custodians of the imperial interest lived, were little islands engulfed by the vast ocean of dirt, represented by the vast majority of people.Cities were by no means unknown to India, but in ancient India, they were integral parts, organically related to the rest of the country and society. But modern cities are exotic centres of commercial and industrial exploitation. Cities in ancient India were the flowers of cultural and artistic excellence of the nation, modern cities are just parasites, preying on and debilitating the country. On the basis of your reading of the above passage answer the following questions briefly : (a) What is the urgent need of the hour in villages? (b) What is the greatest impediment to progress in villages? (c) What do you understand by the third world countries? (d) What was an important part of India’s freedom movement? (e) What differentiates the ancient Indian cities from the modern ones? (f) What are the modern cities like? (g) What is referred to as ‘artificial showpieces’? (h) Describe the two worlds. |
|
Answer» (a) Rural Development (b) Pessimism in the villages. (c) Where the standard of living is pathetic. (d) The country comprised mainly of stagnating villages-hence immediate development required i.e. Rural Development. (e) The commercial and industrial exploitation. (f) Just like parasites, preying and debilitating the country. Just the opposite of ancient cities. (g) Cities that were the product of western colonialism. (h) (i) Posh areas where the affluent lived. (ii) Vast majority lived in the vast ocean of dirt. |

Read the following passage carefully.As civilization proceeds in the direction of technology, it passes the point of supplying all the basic essentials of life i.e. food, shelter, clothes and warmth. Then we are faced with a choice between using technology to provide and fulfil needs which have hitherto been regarded as unnecessary or, on the other hand, using technology to reduce the number of hours of work which a man must do in order to earn a given standard of living. In other words, we either raise our standard of living above that necessary for comfort and happiness or we leave it at this level and work shorter hours. I shall take it as an axiomatic that mankind has, by that time, chosen the latter alternative. Men will be working shorter and shorter hours in their paid employment. It follows that the housewife will also accept to be able to have more leisure in her life, without lowering her standard of living. It also follows that human domestic servants will have completely ceased to exist. Yet the great majority of the housewives will wish to be relieved completely from the routine operations of the home such as scrubbing the floors or the bathe or the cooker, or washing the clothes or washing up, or dusting or sweeping, or making beds. By far the most logical step to relieve the housewife of routine is to provide a robot slave which can be trained to the requirements of a particular home and can be programmed to carry out half a dozen or more standard operations (for example, scrubbing, sweeping and dusting, washing up, laying tables, making beds), when so switched by the housewife. It will be a machine having no more emotions than a car, but having a memory for instructions and a limited degree of instructed or built in adaptability according to the positions in which it finds various types of objects. It will operate other than more specialized machines, for example, the vacuum cleaner or washing machine.On the basis of your reading of the above passage, answer the following questions briefly : (a) What is the first basic use of technology? (b) How will women benefit from technology? (c) When will domestic servants disappear? (d) What are the advantages of using robots? (e) How do robots work? (f) What is the added function of a robot? (g) Who would you choose between a domestic servant and robot slave? (h) What are your views regarding technology and leisure in our life? |
|
Answer» (a) To provide comfort and ease by fulfilling basic needs. (b) Improved/better standard of living and they will have more leisure. (c) When basic needs are satisfied/ taken care of, then there will be no need for domestic servants. (d) Relieves us completely from (daily) household work thus, leaving enough time for leisure-happiness. (e) Programmed as per one’s requirement with set instructions into it. (f) It can operate other than the more specialized machines like vacuum cleaner and washing machine. (g) It is an individual choice. (h) Technology is a boon providing happiness which is a must in our life and leisure is freedom to choose a past time or enjoyable activity. |

Chess is not just for people. Computers have been playing chess since the 1970s. At first they did not play well. They made mistakes. As time went on they grew, stronger. In 1997, a computer beat the best player in the world for the first time. it was a computer called Deep blue. Deep Blue was big. It took up a whole room. By 2006 a cell phone could beat the best players in the world. Chess surely has come a long way. Don't you think so ?(i) Where did modern chess originate ?

Answer» 112, Model Town Delhi 17 July 20XX The Editor The Times of India Delhi Subject : Growing Number of Road-Accidents Sir, Through the columns of your reputed newspaper, I wish to draw the attention of the general public towards the large number of accidents taking place especially in the metropolitan cities. The reason for this can be numerous, the foremost being the thrill of speed. People do not, generally, follow the traffic rules. They are always in a hurry to reach the destination. Moreover, most of the people these days are under stress which leads to the loss of concentration. Drunken driving, distraction like mobile phones, music etc., can also be one of the reasons the for the growing number of road accidents. Everyday, we see under-age drivers i.e., small-children driving to school or the coaching classes which again leads to rough driving or an increase in traffic. This problem can be overcome if more policemen act as deterrents. Stricter punishments should be given for even a small violation of the traffic rules. Children should be taught traffic rules at schools so that they learn to follow them. Parents can also be held responsible for the underage drivers. Moreover, carpools or public transport should be adopted in order to have lesser traffic on the roads. I hope you will publish this letter in your newspaper so that the general public becomes aware of this menace and cooperates up with the traffic police to solve this problem. Thanking you Yours sincerely Arun |

Answer» While coming out of the bank I saw a monkey walking menacingly towards me. I panicked. The monkey snatched my bag and ran up a nearby tree. I looked around for help, but all I could see was people who were interested in the incident but not really interested in helping me out. So finally, 1 decided to do it all myself. I looked around for a stone, grabbed it and aimed it towards the monkey He was quite alert and as soon as I threw the stone, he jumped to another tree. Now I was left without any option other than to be on the mercy of that monkey. But then, my eyes caught a horrifying view, he was opening my bag. Slowly he took out a banana or rather a dozen of them from my bag and discarded my bag as waste. I quickly went and picked up my bag without losing a second. I briskly walked away from that monkey with my bag held tight. And as I walked away my fear and panic was replaced with a smile that the innocence of that monkey brought on my face. |

(i) What is the line of sight communication? (ii) Why is it not possible to use sky wave propagation for transmission of TV signals? |
|
Answer» (a) LOS Communication: The propagation of a radio wave in a straight line from transmitting to receiving antenna on the ground is called line of sight communication. (b) TV signals have high frequency range 100 to 200MHz. Ionospheric layers do not reflect back such high frequency signals. Hence, sky waves cannot be used for transmission of TV signals. |

How does one explain the emission of electrons from a photosensitive surface with the help of Einstein's photoelectric equation ? |
|
Answer» K.Emax=hv-ϕ where v is the frequency of incident radiation and ϕ is the work function for the given surface Einstein's photoelectric equation can be used to explain emission of photoelectric electrons. Einstein assumed that light wave of frequency v can be considered a stream of photons. When this photon interacts with the electron it gives entire energy to electron which is one to one interaction photon is absorbed and rest energy is used by an electron as KE. |
