Friction is the only reason for the loss of energy.

Chain reaction is possible only when the loss of neutrons is ______________ the neutrons produced.

Assertion : In a microbial fuel cell bacteria are involvec in oxidation only. Reason: It helps to produce energy.

(a) Explain perfect inelastic collision and derive an expression for loss of kinetic energy in perfect inelastic collision.

Assertion and Reason. Mark the correct choice as:Assertion:Temperature is the measure of the heat energy.Reason:Energy is the capacity to do work.

A ball at rest is dropped from a height of 12m. It loses 25% of its kinetic energy in striking the ground , find the height to which it bounces. How do you account for the loss in kinetic energy ?

In the following question, a statement of Assertion is followed by a statement of Reason. Mark the correct choice. Assertion: In an elastic collision of two billiard balls are in contact with each other. During the short time of collision, kinetic energy is conserved. Reason: Energy, spent against friction does not follow the law of conservation of energy
