One way to calculate the radius of a star is to use its luminosity and temperature and assume that the star radiates approximately like a blackbody. astronomers have measured the characteristics of central stars of planetary nebulae and have found that a typical central star is 16 times as luminous and 20 times as hot (about 110,000 k) as the sun. find the radius in terms of the sun’s. how does this radius compare with that of a typical white dwarf?

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.
