Question

What causes a supernova?(1 point) Responses energy of heat energy of heat energy of a nebula energy of a nebula force of a nebula force of a nebula force of gravity

Answer 1

A supernova is primarily caused by the force of gravity. In the case of a massive star, when it exhausts its nuclear fuel, gravity causes the core to collapse, leading to a supernova explosion. In the case of a white dwarf in a binary system, it can accumulate material from its companion star until it reaches a critical mass, triggering a thermonuclear explosion. So, the correct response would be "force of gravity."
