assume a charge starts at rest on an equipotential surface, is moved off that surface, and then is eventually returned to the same surface at rest after a round trip. How much work did it take to do this? Explain.
If we can treat the atom as a 'box' of size 20 nm for an electron, what wavelengths could this electron have
A 3500 kg block falls vertically through 5 m and then collides with a 400 kg pile, driving it 3.0 cm into bedrock. Assuming that the block-pile collision is completely inelastic, find out the magnitude of the average force on the pile from the bed..
