Chapter 10, Problem 7(choose chapter or problem)
The Earth is not a uniform sphere, but has regions of varying density. Consider a simple model of the Earth divided into three regionsinner core, outer core, and mantle. Each region is taken to have a unique constant density (the average density of that region in the real Earth): (a) Use this model to predict the average density of the entire Earth. (b) If the radius of the Earth is 6380 km and its mass is determine the actual average density of the Earth and compare it (as a percent difference)with the one you determined in (a).
