Solution

The energy conservation in the given casses are follows

1) when a jar of marble is shaken by a person the muscular energy of the person is converted into kinetic energy of the marbles as they start moving and sound energy.

2) In washing machine the electric energy is converted into rotational kinetic energy.

3) In firecracker the chemical energy converted into in heat energy, light energy and sound energy.

A jar contains 24 marbles. Some of these are green and others are blue. If a marble is drawn at random from the jar, the probability that it is green is $\frac{2}{3}$ . Find the number of blue marbles in the jar.

Imagine a gravity free laboratory, in outer space, where you are asked to study the motions of a large number of marbles kept in a transparent cubical jar, as you give the jar quick, small jerks in random directions. You will observe, that after giving a sufficient number of jerks, the marbles start moving rather chaotically, i.e., each marble bounces off other marbles every now and then, and takes a random trajectory between two points due to these collisions. You seem to have given some kinetic energy to each marble, when the jar was being shaken. What happens when you release the jar suddenly, leaving it suspended in space? Assume all collisions between the marbles to be perfectly elastic.
