The head of a nail is 0.32 cm in diameter. You hit it with a hammer with a force of 25 N.

What is the pressure on the head of the nail? (Express your answer to two significant figures.)

If the pointed end of the nail, opposite to the head, is 0.032 cm in diameter, what is the pressure on that end? (Express your answer to two significant figures.)
