a) Given the Sun’s luminosity today, (L = 3.39x10^33 erg s^-1) how many protons are consumed per second by nuclear reactions in the center of the Sun?

b) Assuming that 2 protons are converted into 2 neutrons each time the Sun makes 1 4He nucleus, what is the flux of neutrinos from the Sun at the Earth’s orbit? Give your answer in [number of neutrinos per second per square centimeter].
