When compared to strong nuclear force gravitational force is a. weaker; it is related to massb. stronger; it is related to charge c. weaker; it is related to charge d. stronger; it is related to mass

A.  weaker;it is related to mass

Explanation:

Nuclear force is a fundamental force which act at small distance range. Its range of distance work for fermi order distances which means for the range of radius of nuclei this force will work.

It is the strongest force among all fundamental forces and only depends on the distance between two nuclei. If distance range is more than fermi order range then the nuclear force will be zero.

While gravitational force between two objects depends on mass as well as distance of two objects and given by formula

as compare to all other fundamental forces this gravitational force is the weakest force among all.

So here correct answer will be

A.   weaker;it is related to mass

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
