Solution 11QQ:
Step 1 of 3:-
In this problem, we have to explain which of the given star will have the longest life time.
We know that, the more massive a star is, the more energy it releases in order to avoid gravitational collapsing.
The released energy increases it’s temperature which don’t allow the star to collapse under it’s own gravity.
