The phase of the moon in which the whole disc of the moon is visible is known as the _______ phase.

The first of a month is the new moon day. On fifteenth of the same month, which of the following figures would represent the phase of the moon?

A rocket is fired from the earth to the moon. The distance between the earth and the moon is r and the mass of the earth is 81 times the mass of the moon. The gravitational force on the rocket will be zero when its distance from the moon is

Find the gravitational due to the moon at its surface. The mass of the moon is 7.36xx10^2 klg and the radius of the moon is 1.74xx10^m . Assuming the moon be a spherically symmetric body

The mass of the moon is about 1.2% of the mass of the earth. Compared to the gravitational force the earth exerts on the moon, the gravitational force the moon exerts on earth
