A source of emf is connected across one pair of opposite junctions (A and C), and a galvanometer G across the other opposite pair (B and D). The key K 1 is closed first and then K 2 . The value of R is varied till the galvanometer shows no deflection, i.e., I g = 0. Then, the bridge is said to b..

Trees which are useful to the tribal people are planted on community land, individual properties and other public land. The main objectives of social forestry are: Efficient use of public and private land to produce firewood, fodder and timber in a decentralised man..

The p-block contains several elements of great social and economic importance as well as chemical interest. Examples include the use of aluminium as a structural material, the importance of silicon and germanium as semiconductors, and the use of sulphur, phosphor..

This is used to measure an unknown resistance accurately. It consists of 4 resistors (2 fixed known resistances P and Q, a known variable resistance R and the unknown resistance X) connected as shown in the figur..

Biology invariably uses knowledge and techniques from other branches of science, to solve its complicated life processes. Most of the recent discoveries and inventions in biology have resulted from the joint endeavour between biology and physical sciences and even biology and s..

Although population of some animals is also studied, the population of human beings is most extensively studied. Whenever the word population is used, it connotes the human population. Population is one of the most important subjects known for having large scale ramifications on eco..

Introduction - Although population of some animals is also studied, the population of human beings is most extensively studied. Whenever the word population is used, it connotes the human population. Population is one of the most important subjects known for having large scale ramificatio..

The simplest approach to the design of modems is to treat the entire PSTN as a linear analog network. [Note that PSTN is almost entirely due to the use of pulse-code modulation (PCM) for the transmission of voice signal..

Addiction is defined as a habit forming dependence of a person on some harmful materials such as tobacco, alcohol, drugs (psychotropic). The repetitive dependence factor in use of these materials will make a person insensitive to these intoxicants / narcotics. This further promotes ..

a) Ban on use of plastic bags (below 20 microns thickness) - which are major cause of pollution in cities b) Recycling of plastic wastes to manufacture many 'remake' items c) Ban on deforestation d) Encouraging forest replantation programmes e) Encouraging social and agro fores..
