    The moment of inertia of a solid sphere

    Okay I get it, thanks for clearing that up for me! I apply the parallel axis theorem to the sphere, and the moment of inertia for a rod with the axis of rotation at the end is (1/3)ML^2

    An Enclosed Mass Profile problem

    Homework Statement Find the enclosed mass profile M(r) in terms of R* and the total mass M* of the star. Homework Equations dMr/dr = 4(pi)r2(density) density is given as: rho(r) = (rho_c)[1-(r/R*)2] Where rho_c is the central density and R* is the radius of the star. 3. Attempt at a...
