An elephant was standing on a bridge. The mass of the elephant was 5,000 kilograms. (That is about ½ a ton.) If the gravitational acceleration for the elephant was about 10 m/s2, how much force did the bridge need to apply to the elephant so it wouldn't fall?

answer: strength i guess

explanation:

no sign of dia of fuel cell

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.
