A stream of electrons, each with a kinetic energy of 450 eV, is sent through a potential-free region toward a potential barrier of "height" 500 eV and thickness 0.300 nm. The stream consists of 1 x 1015 electrons. How many should tunnel through the barrier? Pick the closest answer. The electron mass is 9.10938 x 10-31 kg.
