# Sun's Nuclear Reaction and Radiation

The sun currently is still in its hydrogen burning phase, converting hydrogen into helium through the net reaction of Eq. (6.47). It produces power at the rate of about 4 x 1026 W. (a) What is the rate (in kg/s) at which mass is being converted to energy? (b) How many 4He nuclei are produced per second? (c) What is the radiant energy flux (W cm~2) incident on the earth? The average distance of the earth from the sun is 1.5 x 1011 rn.

Here is eq 6.47

4(}H)—>• He + 27 + 2/3+ + 2zy, Q = 26.72 MeV. (6.47).
