What are the characteristic of a magnet

They seek the path of lease resistance between opposite magnetic poles, in a single bar magnet they attempt to form closed loops from pole to pole and never cross each other.

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

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.
