The probability of two protons tunneling in the Sun's core is Ptunnel 1010. This means that out of each
1010 pairs of protons, one pair tunnels successfully. Make an estimate showing that this probability can
account for the 1038 fusion reactions that take place each second in the Sun's core. Hint: Assume that
the Sun's core contains about 40% of its mass.
(a) Calculate the rate at which the Sun generates neutrinos. Assume that energy production is entirely by the proton–proton fusion cycle. (b) At what rate do solar neutrinos reach Earth?
The power output of the Sun is 4 × 1026 W.
Part (a) If 93 % of this is supplied by the proton-proton cycle, how many protons are consumed per second?
Part (b) How many neutrinos per second should be incident on every square meter of the Earth from this process? This huge number is indicative of how rarely a neutrino interacts, since large detectors observe very few per day.
