Use the classical ideal gas law, the dimensional relation between mass, density, and radius, and the virial theorem, to find the scaling of the stellar radius r∗ with total mass M, mean particle mass m¯ , and core temperature Tc. Using the values of these parameters for the Sun, derive the radius of the star.

b would be the answer

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
