There are a variety of ways of estimating the ages of various objects in the universe. describe two of these ways, and indicate how well they agree with one another and with the age of the universe itself as estimated by its expansion.

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.
