Answer:
27 days
Explanation:
Earth has only one natural satellite-the moon. The moon is about one-fourth the Earth's size. Moon rotates about its own axis as well as revolves about the Earth. Its revolution period around Earth is 27.32 days ( days) where as its rotation period is 27 days. Due to this synchronization of the two periods, only one side of the moon is always visible to us.

Answer:
The velocity of the other fragment immediately following the explosion is v .
Explanation:
Given :
Mass of original shell , m .
Velocity of shell , + v .
Now , the particle explodes into two half parts , i.e .
Since , no eternal force is applied in the particle .
Therefore , its momentum will be conserved .
So , Final momentum = Initial momentum
The velocity of the other fragment immediately following the explosion is v .
