In the "4p" nuclear fusion reaction 4 nuclei of hydrogen (i. e. 4 protons) fuse into 1 nucleus of helium, emitting energy. describe qualitatively (i. e. in words) the reaction: how is it possible to overcome the electric repulsive force? what is the nuclear force? how is the energy generated?

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
