The diagrams above were used to illustrate the arrangement of the particles of a substance in three different states of matter. which of the following statements is correct? circles question 7 options: the particles in diagram 3 move fast enough to break away from each other. the particles in diagram 1 move faster than the particles in diagram 2. the particles in diagram 2 are affected by electric and magnetic fields. the particles in diagrams 1 and 2 are locked in place.

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?
