(ii) in an engine, an almost ideal gas is compressed adiabatically to half its volume. in doing so, 2630j of work is done on the gas. (a) how much heat flows into or out of the gas? (b) what is the change in internal energy of the gas? (c) does its temperature rise or fall?

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
