1. Assume that the density at the center of the Sun is 1.53 × 105kg m−3and that the mean opacity at the Sun’s center is =0.217 m2kg−1.(10 points total)(a) Computethe mean free path of a photon at the center of the Sun.(b) Using your answer from part (a), computethe average time, in years, it would take for the photon toescape from the Sun if this meanfree path remained constant to the surfac
