5. We can sample rocks at the surface of the Earth to determine their density, but to place limits on the nature of materials deeper in the Earth, we need to determine the AVERAGE density of Earth. We can do that by studying the interaction of the Earth with the moon. In doing that determination, you would need all but one of the following. Which one don’t you need? The Earth’s moment of inertia The radius of the Earth The gravitational constant (G) The orbital velocity of the moon The distance from the Earth to the Moon
