Answer:
Option A
Explanation:
As we all know, energy can never be created . Also it can never be destroyed. However, it can only be changed from one form to the other. In this case, when a pool ball is striked by a stick, the kinetic energy of stick is transferred to the ball along with release of sound. Sound is just another form of energy.
Now, when this ball strikes other balls, the same process is repeated i.e the ball strikes another ball and passes on its kinetic energy along with release of sound energy. Every time sound is released, the amount of kinetic energy transferring from one body to other reduces.
