Consider the motion of the moon and com plete the following parts a - g of this question. a. What commonly used unit of time in every day life has been derived from the motion of the moon? b. What period of the moon was used to obtain the above unit of time?

The moon rotates in an elliptical orbit which is circular and synchronous motion of rotation.

Explanation:

Solar time is the commonly used measure for the time that progresses according to the motion of the sun on its axis, and it's not completely uniform the moon obits every the Earth once every 27.322 days. As the earth rotates in the sidereal motion for the moon it takes 13.2 degrees from the start to rotate on the same axis. Moving in a west to the east direction in an anticlockwise format. As the sidereal period is determined by the 360-degree revolution in which the celestial bodies revolve each other the repeated cycles for celestial bodies have been observed on earth.
