b. step 2
c. none of the steps
d. step 3
2. Assume that the entire luminosity of the Sun is due to the PP chain reaction. The complete
PP chain reaction converts 4 hydrogen nuclei into 1 helium nucleus, according to the following
reaction:
4 H - He + 2e* + 2v.
a. Estimate the amount of energy released by one complete reaction.
b. Estimate how many of these reactions occur per second in the Sun, and how many
neutrinos the Sun produces each second.
c. Estimate the flux of neutrinos (in v's s' cm?) passing through the Earth.
1. If 0.048 × 10-27 kg of mass is converted to energy in a single hydrogen fusion reaction, how much mass is lost over the lifespan of the sun?
