Synthetic detergents have advantage over usual soaps as far as cleansing power is concerned. But use of synthetic detergents over a long time creates environmental pollution. How can the pollution caused by synthetic detergents be minimised? Classify the detergents according to their chemical nature.

How can the energy stored in an inductor be utilised?

What is nuclear fission? What are controlled and uncontrolled fission reactions? How can the energy released in such reactions be used for practical purposes?

A bullet of mass 250g , moving with a horizontal velocity of 400 m*s^(-1) , gets embedded in a target. The target of mass 4.75 kg can move freely. Find the loss of kinetic energy due to this collision. What happens to this energy loss ?

A ball of mass m falls from a height h on a stationary horizontal plane and bounces up . If the coefficient of restitution is e, show that, the loss in kinetic energy due of impact is mgh (1-e^2) .
