Write a short paragraph that explains how a sport using a ball would be played differently on a planet of your choice. For example, how would gravity affect a basketball game on Saturn? Or how would gravity affect a baseball game on Mercury? (Doesnt have to be a full paragraph answer I just need a gist of what it is)

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
