til the end of the earth

To avoid the risk of electric shocks, the metal of an electrical appliance is 'earthed'. Earthed means to connect the metal case of the appliance to the earth (at zero potential) by means of a metal wire (copper) called the earth wire. One end of t..

The creation of a life form, by a similar life is called reproduction. Reproduction is the extension of life of a species at a given time. It is a means of perpetuation of the species and also multiplies their number. By this process, the individuals transmit life to the next generation and t..

During thunderstorms, large amount of electrical charge separation takes place in the clouds. As a result, some regions of the cloud have overall positive charge, while others have overall negative charge. When this separation becomes sufficient, the air ionizes and becomes conducting. This results..

It is a means of perpetuation of the species and also multiplies their number. By this process, the individuals transmit life to the next generation and thereby..

> at the bottom of the mantle. Here, the mantle ends and a sudden increase in density occurs. It is here that the core of the earth begin..

When the rod X with positive charge on it is brought near C [figure (a)], the negative charges get attracted and they get concentrated on the cap C. On the other hand, the positive charge gets repelled and they get concentrated at the distant end on the leaves L and M. The leaves L and M..

An Alternative method of charging body by induction is the earthing process. A positively charged acetate strip is brought near a neutral, insulated conductor. The negative charge is attracted to the positively charged body at the end 'A' and the positive charge is repelled and ..

Introduction - Very often, energy is generated at one place but consumed elsewhere. The transportation of energy from its source to the receiving end can be done in two ways: By actually moving the matter carrying kinetic energy and delivering it to the other end. By the vibration of..

Universe - Universe consists of all matter and all light and other forms of radiation and energy. It consists of everything that exists anywhere in space and time. The universe includes the earth, everything on the earth and within it and everything in the solar system. All star..

'S' is a large spherical conducting shell of radius few meters. C 1 and C 2 are the two supporting pillars. An insulating material like silk acts like a conveyor belt wound over two pulleys P 1 and P 2 . The pulleys move with the help of a motor. B 1 and B 2 are two spray combs. D is the disc..
