Question

Statement 1: Only one side of the moon is visible from Earth

Statement 2: The moon completes one revolution around Earth in $27\frac{1}{3}$ days.

• A. Only statement 1 is true
• B. Only statement 2 is true
• C. Both the statements are true. Statement 2 is not the correct explanation of statement 1
• D. Both the statements are true. Statement 2 is the correct explanation of statement 1

Answer 1

The correct option is C

Both the statements are true. Statement 2 is not the correct explanation of statement 1

An object is said to be tidally locked when the time period for revolution and rotation are almost equal. Moon takes $27\frac{1}{3}$ days to complete one revolution around Earth and also same time to complete one rotation around itself. Hence Moon is tidally locked to Earth.
