The model shows sunlight reaching Earth. Four points are shown on different parts of earth. based on the position of earth in the model, which point is experiencing nighttime during the summer month. (diagram is in the picture)
A:point1
B:point 2
C:point 3
D:point 4​

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?
