d. Hydrogen fusing into helium
When stars like sun burn their nuclear fuel, they become white draft. They fuse hydrogen cores into helium. This fusion produces heat and pressure in the outward direction. But, this pressure is balanced due to the gravity of star’s mass. In this way, planetary nebula is created. The major benefit of white draft is that they warm enough planets to keep water in liquid state on their surface.
Multiple choice answer would be "None"
White dwarfs are radiating stored heat from earlier reactions.
Technically, it would be the last fusion stage the star went through
BEFORE it became a white dwarf, but that's nit-picking.
when a star's core collapses, it has no outer layer of resources to use, so it uses the resources inside of it, nuclear fusion is a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
there is no change in the electric potential energy as it is in rest on both conditions.
in this image, you can see solar radiation going through ocean water.
no image, but probably absorption
