Calculate the velocity of an electron ejected if 300.0 mm of light is applied to the surface. a wavelength of 795 nm has sufficient energy to eject electrons.

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
