In figure 2, which object (a, b, or c) has the highest density? why?

C

Explanation:

We just have to remember that density of an object is given by the quantity of matter that is located in a certain volume, so the more matter in the less volume the greater the density, so as we can see the B image is the one that has the most volume so that wouldn´t be the one with the highest density, the A has the same volume as the C but has less particles, so the one with the highest density would be C because has the less volume and the most particles.

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.
