If an electric circuit was analogous to a water park, then the electric current would be analogous to the a. pipes which carry the water through the circuit b. the people which flow from the top of the water ride to the bottom of the water ride c. the rate at which water is pumped onto a slide d. the chance in potential energy of the riders e. the speed at which riders move as they slide from the top to the bottom of the ride

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?

In which of these cases are the two wave points considered to be in phase with each other?
