Answer:An atomic nucleus consists of protons and neutrons, collectively called nucleons. Although protons repel each other, the nucleus is held tightly together by a short-range, but very strong, force called the strong nuclear force.

As per Newton's law we know that
F = ma
here we know that
F = 4 N
m = 2 kg
so from this equation we will have
4 = 2 a
a = 4/2 = 2 m/s^2
so the acceleration will be 2 m/s^2
The Answer Is D Because When Uu Magnify Large Items The Image Is Reflected Back To The Magnifying Glass Which Makes The Image Appear In The Back
It works by you putting leverage on one side makes more force go to the other side so if you put a crowbar in between a door and you push on one side the other will push the opposite side with more force<span />
