The sun radiates energy at the rate 3.8*10^26w. the source of this energy is fusion, a nuclear reaction in which mass is transformed into energy. the mass of the sun is 2.0*10^30kg. part a) how much mass does the sun lose each year? (delta m)

part b) what percentage is this of the sun's total mass?

(deltam/m) %

part c) estimate the lifetime of the sun. (t)
