A 1 M star becomes a red giant with luminosity of 10^2 L and radius R = 100 R. Suppose that the outer very thin layer of the star has a mass of 0.1 M and absorbs all of the radiation. For this problem, you need to remember that the momentum of a photon is p = E/c and that force is momentum per unit time. Problem 3.4.1 What is the momentum per second that the outer layer absorbs

Answer rating: 100% (QA)

To calculate the momentum per second that the outer layer of the star absorbs we need to consider the radiation energy being emitted by the stars lumi... View the full answer
