If you were to measure the distance from Earth to the Andromeda galaxy, would you use light-years or AU?

you would use light years

Explanation:

If your talking about the Andromeda galaxy its pretty far away and light years are used to measure things really far away

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.
