Assuming that the entire energy resulting from the p–p chain reaction escapes from the sun’* surface, calculate the flux of neutrinos received on earth. Take the earth-sun distance as 1.5×108km. Assume that the total energy output of the sun is LΘ = 3.83 × 1026 Js−1, and that each α-particle produced implies the generation of 26.72 MeV
