Write an equation that is equivalent to Newton's Second Law for rotational motion. (Use the following as necessary: I, m, and α.) HINT τ = Name the corresponding physical quantities included in the equation and their units. (If the physical quantity is not included in the equation, choose NA.) τ I m α

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?
