The roche limit is the radial distance from the center of a planet at which the tidal forces exerted by the planet on one of its moons will overcome the gravitational force holding the moon together. the result is that the moon will be torn apart (or never succeed in forming in the first place) and eventually form a ring around the planet from the material of the disintegrated moon. the roche limit can be determined from?

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
