What is the basic nature of the fusion reaction that provides the energy source for the sun, and drives the mechanism by which all stars shine?
a
protons and neutrons are attracted to each other by gravity, allowing the electromagnetic force to complete the job of binding them together.
b
protons are attracted to each other by their similar charges strongly enough to bind together, allowing the electromagnetic force to complete the job of binding them together.
c
if propelled quickly enough, protons and other nuclear fragments can come close enough to overcome their electromagnetic repulsion, allowing the short-range strong nuclear force to come into play.
d
heavy elements such as iron fuse together, releasing protons and neutrons to continue the chain reaction.
e
heavy elements such as iron split apart, releasing protons and neutrons to continue the chain reaction.
