g A circular swimming pool has a diameter of 10 m, the sides are 4 m high, and the depth of the water is 3 m. How much work (in Joules) is required to pump all of the water over the side

Explanation:

Generally the equation for momentum is mathematically given by

Diameter

Radius

Height

Depth

Generally the equation for Area of the circle is mathematically given by

Generally the equation for Work done is mathematically given by

Where

Therefore

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.
