Un bloque m (1.00 kg) en un plano inclinado a 5° sin fricción está unido mediante una cuerda delgada que pasa por encima de una polea que no ejerce fricción a un bloque suspendido m (200 g). los bloques se liberan des de el reposo y la masa suspendida cae 1.00 m antes de golpear el piso. determine la rapidez de los bloques justo antes de que m golpee el piso.

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
