Consider an electron initially moving in the positive x-direction along the negative x-axis with an energy of 1.0 ev. at the origin the electron encounters a square barrier; the potential energy u (x) changes abruptly, from u (x) = 0 for x < 0, to u (x) = v for 0 < x < a, and back to u (x) = 0 for x > a, where the barrier width a = 1.0 nm . what is the transmittance if v = 1.1 ev?

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
