Question

In the field of physics, the notability of fusion reactions becomes significant when they result in a stellar mass exceeding how many solar masses?

A) 10 solar masses
B) 1 solar mass
C) 5 solar masses
D) 20 solar masses

Answer 1

Fusion reactions become significant when they result in a stellar mass exceeding 20 solar masses.

Step-by-step explanation:

The notability of fusion reactions becomes significant when they result in a stellar mass exceeding 20 solar masses. In massive stars, fusion reactions can produce more complex nuclei. The fusion of hydrogen nuclei to form helium is the primary source of energy in the Sun. This fusion reaction releases a large amount of energy and is responsible for the Sun's heat and light.
