Alarge pendulum with a 200-lb gold plated bob 12 inches in diameter is on display in the lobby of the united nations building. the pendulum has a length of 75 ft. it is used to show the rotation of the earth—for this reason it is referred to as a foucault pendulum. part a) if the pendulum were to be taken to the moon, where the acceleration of gravity is g/6, would the period increase, decrease, or stay the same?

part b) check your result in part a by calculating the period of the pendulum on the moon.

9.59143 s

23.4941 s

Explanation:

L = Length of pendulum = 75 ft

g = Acceleration due to gravity = 9.81 m/s²

Time period is given by

On Earth

The time period on Earth is 9.59143 s

On Moon

The time period on Moon is 23.4941 s

we need to know the time interval during which the force acts. impulse of force = momentum change

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
