A bird is standing on an electric transmission line carrying 3000 A of current. A wire like this has about 3.0 x 10-5 22 of
resistance per meter. The bird's feet are 6 cm apart. The bird
itself has a resistance of about 4 x 105 12. The bird
experiences a potential difference of 0.0054 V. What current
goes through the bird?

the bal will not change its velocity.

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.
