What type of nuclear fusion is going on in the main sequence of a star? (Hint: ____ into ____ )
|
|
Gravity
|
|
|
Helium
|
|
|
Hydrogen
|
|
|
Lithium
|
Explanation:
Detailed explanation-1: -Because fusion is so temperature-sensitive, in a main-sequence star, fusion of hydrogen into helium occurs only in the hot, dense central core. All main sequence stars (including the Sun) are in hydrostatic equilibrium.
Detailed explanation-2: -Nuclear fusion is the process where two small atoms are heated up and fused together. The process involves a few basic steps: atoms are heated, the atoms collide with substantial force overcoming the coulomb force between them, the atoms fuse together, and a large amount of energy is released.
