A container holds 2.3 mol of gas. The total average kinetic energy of the gas molecules in the container is equal to the kinetic energy of a 7.2x10-3 kg bullet with a speed of 960 m/s. What is the Kelvin temperature of the gas?
A proton has a speed of 0.85c. FIRST Calculate the rest energy of the proton, Calculate the kinetic energy of the proton
Suppose you have two boxes that conceal what is inside, althougheach has two wires coming out of the interior. You have atyour disposal some batteries, wire and identical flash tlight bulbs.
assume you would enter a vacuum chamber (on Earth), that is, a chamber with no air in it. Inside this chamber, if you dropped a hammer and a feather from the same height at the same time, both would hit the bottom at the same time.
