Answer:

c) A is true but R is false.

R is false because the moving hammer has kinetic energy and not potential energy which is used to hammer the nail.

Answer:

A: A moving hammer drives a nail into wood. R: A moving hammer has potential energy in it. Both A and R are true, but R is not the correct explanation of the assertion. Hence the correct option is b).

Explanation:

Statement A is true because a moving hammer indeed drives a nail into wood. The hammer exerts a force on the nail, causing it to move through the wood.

Statement R is also true because a moving object does have potential energy. When a hammer is raised above a surface, it gains potential energy due to its position with respect to the surface. This potential energy is converted to kinetic energy as the hammer is brought down to drive the nail into the wood.

However, statement R does not provide a correct explanation for statement A because the potential energy in the hammer is not what drives the nail into the wood. It is the kinetic energy of the hammer that is transferred to the nail upon impact that drives it into the wood. Therefore, option (b) is the correct choice
