56. A rectangular potential barrier has a width l = 0,1 nm. The difference between the height of the potential barrier and energy moving in the positive x-axis direction of the electron U - E = 5 eV. Determine how many times to change the transmission coefficient D potential barrier for an electron, if the difference U - E increases 4 times.
