The moon orbits the earth at a distance of about 60 earth radii away. However, its gravitational pull is still large enough to cause the ocean tides on the earth. Based on your knowledge of the force of gravity, which of the following could you infer would increase the size of the earth's ocean waves the most? A. Double the mass of the moon B. Move the moon to only 30 radii away from the Earth C. Double the moon's orbit speed D. Double the spin speed of the moon

What is the answer for this. the correct answer only
