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.

Suppose that a cylindrical tank 6 meters high with a radius of 2 meters is filled to the rim with water. the tank is buried so that the top of the tank is 1 meter below ground level. the space above the tank is not filled with water. calculate how much work needs to be done by a pump to pump the water out of the tank up to ground level. (the water weighs 9,800 newtons per cubic meter.)
