Estimate the number of Solar neutrinos passing through adetector on the Earth in one second. Assume that the detector has asurface area of 1.0 square meters and is aligned so that it facesdirectly towards the centre of the Sun. Assume that every neutrinotravels without any change (i.e. none are absorbed or converted toa different particle). Also assume that the energy carried out ofthe Sun by the neutrinos is negligible
