where the pollutant entering the water course affects the quality of water in the vicinity of pollution. For e.g., Sanitary water entering drinking water source through leakage of pi..

As proved earlier, the intensity of sound varies inversely as the square of the distance from the source. If two points are at distances d 1 and d 2 from a point source, then the intensities at these points will be in the inverse ratio of the squ..

A good source of energy should have the following characteristics: It should do a large amount of work per unit mass or volume - it means that the output energy must be more than the input energy. It should have high calorific value. It should be easily accessible - the energy ..

In a homogeneous medium, the velocity of light waves is same everywhere. So the disturbances reach all such particles at the same time. These particles are at the same distance from the source and so they vibrate in phase with each other. The locus of all such particles is called wave fr..

Consider two points 'a' and 'b' in an electrostatic field of a single isolated point charge +..

Water pollution can be point source or non - point source. That is, it can be caused near the source of pollution or where source of pollution is sometimes far away from source..

Water pollution can be point source or non - point source. That is, it can be caused near the source of pollution or where source of pollution is sometimes far away from source. Nature also contributes to water pollution besides ..

Potential Energy of a Single Charge - In the previous chapter, we learnt about specific charge, its location, and its electric field, but here we are considering the potential energy of a charge, in an external field. Consider an external electric field 'E' produced by an external source,..

Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for some purpose or ..
