How far does a photon (light) move in one nm in units of feet?

How can you prove that acceleration due to gravity is the same in a resting and moving frame?

I'm having problems with this: Compare the trajectory of a planet and a comet.

Calculate g at the midpoint of the earth moon system.

Calculate the angular and linear velocity of the surface of the sun and the earth around the sun.

A tritium nucleus explodes by beta decay. An electron leaves with 1x108m/sec. Its mass is 9x10‐31kg. What is the recoil velocity if the 3He+ ion mass is 3x 1.66x10‐27kg. What is the kinetic energy of both particles in Joules and in electron volts (1eV = 1...
