Planets are not uniform inside. Normally, they are densest at the center and have decreasing density outward toward the surface. Model a spherically symmetric planet, with the same radius as the earth, as having a density that decreases linearly with distance from the center. Let the density be 9.0x103kg/m3 at the center and 2.0 kg/m3 at the surface.

What is the acceleration due to gravity at the surface of this planet?

Planets are not uniform inside. Normally, they are densest at the center and have decreasing density outward toward the surface. Model a spherically symmetric planet, with the same radius as the earth, as having a density that decreases linearly with distance from the center. Let the density be 1.70×104 kg/m3 at the center and 2800 kg/m3 at the surface. What is the acceleration due to gravity at the surface of this planet?

Assume that all the mass of a galaxy is in a massive uniform density ball of stars (called bulge by astronomers), with a radius of 1 kpc. The total mass of this bulge is 3 × 1010 M⊙ The volume of a sphere with radius R is: 4/3πR3. The observed rotation curve of the galaxy is flat from 1 to 8 kpc from the center. Astronomers claim that this must be due to the presence of dark matter. How much...
