Hint:In our solar system, planets are revolving around the sun in a particular orbit. Not only revolving, it also rotates. Rotation is the movement of a spherical object in its own axis. Therefore our earth rotates in its own axis and revolves around its orbit. Like earth, the moon is the satellite that revolves around the earth. The rotation depends upon the circumference of the spherical object.

(i) We experience day and night just because of the rotation by our planet, Earth. The earth takes approximately $24$ hours to complete one full rotation.
(ii) Because of the moon’s revolution we experience full moon and no moon. The moon takes approximately $27$ days to complete one revolution around the earth. It rotates once every revolution. This is said to be “synchronous rotation” or tidal locking.
$v = \dfrac{d}{t}$
