Petrol and diesel are used in automobiles and locomotives. Specially prepared fuels are used in ro..

In solution or in their molten states, ions become free to move. On applying an electric field,the ions get drifted towards towards their respective electrodes.Thus, ionic compounds are good conductors of electricity in these states. However, these do not conduct in t..

All living organisms need food for growth, work, repair and maintaining life processes. Food is made up of several components such as proteins, carbohydrates, fats, minerals and vitamins.

When a number of similar waves pass through a medium simultaneously, each wave travels through the medium as though the others were not present. However, at any point in the medium, the net effect of the waves reaching that point at any instant, is produced. The principle of superposition of waves ..
