Two vehicles are driving down the highway at the same speed. One is a motorcycle and one is an 18-wheeler truck. Which has the most kinetic energy?

What are chlorofluorocarbons and what impact do they have on the atmosphere?

Does current flow through or across a resistor?

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?
