When you hold a rectangular object how does the area of the side that is resting on your hand affects the pressure and the force that the object exerts

A rectangular object may have different areas for different sides.

If that object is placed on a hand, the area of its side does not affects the Force. However the pressure it puts on the hand is affected by the area.

Explanation:

The Force that object applies on the hand is given as the product of its mass and gravitational acceleration 'g'. Hence area does not affect the Force and it is constant.

F = mg

Pressure is defined as the Force per unit area.

P = F/A

As the surface area decreases and Force remains constant, the pressure on the hand increases and vice versa.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
