A child's top is held in place upright on a frictionless surface. The axle has a radius of r=3.21 mm. Two strings are wrapped around the axle, and the top is set spinning by applying T=1.65 N of constant tension to each string. If it takes 0.320 s for the string to unwind, how much angular momentum L does the top acquire? Assume that the strings do not slip as the tension is applie

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.
