The diagram below represents two carts with low-friction wheels. A magnet is mounted on each cart. The magnet on cart 2 is twice as strong as the magnet on cart 1. Both carts are kept at rest by the attached spring scales. The sprint scale on the left reads 10 N. What does the spring scale on the right read, in Newtons? Explain your reasoning.

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?
