Problem 104

The sun radiates energy at a rate of 3.9 1026 W. (a) Atwhat rate is the sun losing mass? (b) At that rate, howmuch time would it take to exhaust the suns fuel supply?The suns mass is 2.0 1030 kg, and you may assumethat the reaction producing the energy is about0.7% effi cient. Compare your answer with the sunsexpected remaining lifetime, about 5 Gy.
