. In the movies, you sometimes see a scene where a character fires a bullet at victim, who falls backwards from the impact, but the shooter is standing still. Is this realistic? Or movie effect fiction? Explain using the laws of physics. Assuming a 1 gram bullet and that the victim has a mass of 100 kg each, Ignore friction. Does it make a difference if the shooter is on a rug or ice? Explain.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
