When nuclear fusion begins, what can be said about the internal processes within that star?
Atoms in the star begin to split.
Atoms in the star begin to combine.
The star is turned into a nebula.
The star is turned into a blue giant.
is it b
That is the best answer.
Yes, it is option B: "Atoms in the star begin to combine."
When nuclear fusion begins, the internal processes within the star involve the combination of atoms. Nuclear fusion is a process where two atoms, typically hydrogen nuclei, come together to form a heavier atom, such as helium. This process releases a tremendous amount of energy, which is what powers the star and enables it to emit light and heat. Fusion reactions occur in the core of the star, where the temperature and pressure are extremely high. The intense heat and pressure cause the atomic nuclei to overcome the electrostatic repulsion and collide with enough force to combine and form new elements, releasing an enormous amount of energy in the process.
