Question 134

To calculate the average pressure exerted by a force acting perpendicularly on a flat surface, the size of the force must be known. What else needs to be known?

A

The area of the surface over which the force acts is needed (✓\checkmark✓) and the duration of time for which the force acts is needed (✓\checkmark✓)

B

The area of the surface over which the force acts is needed (✓\checkmark✓) and the duration of time for which the force acts is not needed (×\times×)

C

The area of the surface over which the force acts is not needed (×\times×) and the duration of time for which the force acts is needed (✓\checkmark✓)

D

The area of the surface over which the force acts is not needed (×\times×) and the duration of time for which the force acts is not needed (×\times×)
