kinetic energy is not conserved due to the action of internal friction. knowing the definition of inelastic collisions, do you think gas particles always experience elastic collisions?

The mass of a muon is 207 times the electron mass; the average lifetime of muons at rest is 2.21 μs. in a certain experiment, muons moving through a laboratory are measured to have an average lifetime of 7.04 μs. for the moving muons, what are (a) β (b) k, and (c) p? the rest energy of the electron is 0.511 mev.

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.
