Question
that the density must increase with depth. In this question, we will assume that the density, p, follows the equation: p(r) = 3000 + po(1-7) In which r is the distance from the centre of the Earth, R is the radius of the Earth, and po is a constant. a) Using your knowledge of the mass of the Earth, calculate the value of the constant po b) The radius of the Earth's iron core is about 3500 km. If the equation above is correct, calculate the fraction of the Earth's mass that is in the core.
