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 1.30×10^4 kg/m^3 at the center and 3000 kg/m^3 at the surface. What is the acceleration due to gravity at the surface of this planet?

1.1 Suppose you want to make a scale model of a hydrogen atom. You choose, for the nucleus, a small ball bearing with a radius of [01] mm. The radius of the hydrogen atom is 0.529 × 10−10 m and the radius of the nucleus is 1.2 × 10−15 m. (a) What would be the radius (m) of the model? (b) Suppose that now you want to make a scale model of the solar system using the same ball bearing...

An electron is initially at rest in a uniform electric field having a strength of 1.95 × 106 V/m. It is then released and accelerated by the presence of the electric field. What is the change in the electron’s kinetic energy, in kiloelectron volts, if it travels over a distance of 0.25 m in this field? Over how many kilometers would it have to be accelerated in the same electric field to increase its kinetic energy by 65 GeV? &...
