Question

A star that evolves off the main sequence in about 10 million years probably has?

1) High mass
2) Low mass
3) Medium mass
4) Cannot be determined

Answer 1

A star that evolves off the main sequence in about 10 million years probably has a high mass.

Step-by-step explanation:

A star that evolves off the main sequence in about 10 million years probably has a high mass. According to the information provided, stars of higher mass go through all stages of evolution faster than stars of lower mass. Stars with masses much higher than the Sun's can reach the main sequence in a few thousand to a million years. Therefore, a star evolving off the main sequence in 10 million years suggests that it has a high mass.
