4. what does doubling the voltage do to the strength of the electromagnet?

I believe it would double the strength of the electromagnet as well

Hope this helps!

i. like it i'm gonna edit it tomorrow

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.
