Energy reaches Earth from the Sun at a rate of about 1400W/m2. Calculate
(a) The total power output of the Sun, and
(b) The number of protons consumed per second in the reaction of Eq 31-7 assuming that this is the source of all the Sun’s energy.
(c) Assuming that Sun’s mass of 2.0 X 1030 kg was originally all protons and that all could be involved in nuclear reaction sin the Sun’s “glow” at its present rate? See previous Problem.
