A40 kg box has a surface area of 0.2 m2, determine its pressure.

P = 1960 Pa

Explanation:

The pressure is computed as the force acting upon a surface divided by the area of the surface

The box has 40 kg, it presses on its own surface when placed over a table or any flat area. The acting force is its weight.

The pressure is:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
