Question
if the nuclear fusion reaction of converting 4 H → He occurs at an
efficiency of 0.7%, and that mass is converted into energy according
to the equation E = mc2, then estimate the Main Sequence lifetime of the Sun (spectral type G2)
in years if the Sun (⊙) has a surface luminosity L⊙ = 3.839×1033
erg. Assume the Sun’s core (10% of the total mass) is converted
from H into He. The Sun’s mass is M⊙ = 1.9891 × 1033 g
