Consider, quantum mechanically, a stream of non-interacting particles of mass m each moving along the positive x direction (i. e., from left to right) with kinetic energy e=+v_0/2 toward a rectangular potential barrier given by v(x)=+ v_0 in the region -a1. with v_0=2ev, how wide must be the barrier so that the transmission probability is 10^-3.

porque la cantidad de gases de efecto invernadero alcanzó un nuevo máximo sin precedentes, causando daños muy graves a esta, por eso es importante monitorearla, para controlar el porcentaje de daños que esta causa y poder reducirlo o mantenerlo.

the closer the planet is to the sun, the larger the gravity

e/c, where e is its total energy

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
