Las placas de un capacitor de placas paralelas están en forma horizontal. En el espacio se coloca una losa de material dieléctrico con que llena la mitad inferior del espacio entre las placas. ¿Cuál es la nueva capacitancia resultante

The speed of light can be used to measure the

At what time will the interfering waves have an amplitudeof zero?

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?
