Question 11 of 11 Which model best describes how gravity causes star formation?
A. A long spool of thread is unwound and then wound back up.
B. Two mugs crash into each other and break into many small
pieces.
C. A cup of water is dumped on the ground, where it forms a small
pool.
D. A snowball grows as more snow sticks to it.

D. A snowball grows as more snow sticks to it.

Explanation:

When a star is born, it’s fairly small. However, the stars gravitational pull brings more things (for lack of better term) into it therefore increases it’s size as a snowball would as more things (again, no better term) stick to it.

Hope this helps, it was a pleasure to make your acquaintance.

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.
