Question

Assertion (A): We can see only one face of the moon.

Reason (R): Moon completes one rotation and one revolution in approximately 27 days.

Options

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

We see only one face of the moon because it completes one rotation on its axis in the same time (about 27 days) it takes to revolve around the Earth. This synchronous rotation causes the same side to always face Earth.
