Draw a model of a free body diagram of the demonstration we saw of the tennis ball being pushed on either side by two different people's hands. Include these items: Hand 1, Hand 2, ball, table, Earth. when you draw it put in all of the contact and non-contact using the correct arrows.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

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.
