Answer:
L=55.9m
Explanation:
The equation for the period of a simple pendulum is:
In our case what we know is the period and the acceleration of gravity, and we need to know the length of the pendulum, so we can write:
Which for our values is:
It is position when Moon is between Earth and Sun. In this case gravitational forces of both Moon and Sun pull water in same direction and magnitude of gravitational force is greatest. When Moon and Sun are on opposite sides of Earth gravitational force pulls water in two opposite directions and magnitude of gravitational force is smallest and tide is lower. When Moon is in position that is shown as above or below Earth than magnitude of gravitational force is between those two already mentioned.
The kinetic energy will rise once the body comes back down. As it goes up, the potential energy increases while the kinetic energy decreases. Once the body is at its maximum height, the potential energy is at it’s highest. When it starts falling, it will gain kinetic energy and lose potential energy.
