Physics

The mass of the sun is 2*1030 kg. It currently consists to about70% (mass) of hydrogen. The dominant source of energy for the sunis the pp-chain (type I) fusion process in which four protons fuseinto a 4He core consisting of two protons and two neutrons. Thisprocess releases 26.22 MeV ( = 4.2*10-12 J) of energy. Assume thatto first order the luminosity of the sun remains constant at 1.1times its current-day value. How long will it take for the sununtil the fraction of hydrogen is reduced from 70% to 30%?
