Gconsider two copper wires separated only by their surface oxide layer (cuo). classically, since the oxide layer is an insulator, no current should be possible through the two copper wires. suppose that for the conduction ("free") electrons in copper, the surface oxide layer looks like a square potential barrier of height 10 ev. consider an oxide layer thickness of 5 nm and evaluate the transmission coefficient for conduction electrons in copper, which have a kinetic energy of about 7 ev. what will be the transmission coefficient if the oxide barrier is 1 nm?

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
