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.
