Calculate the electric potential v(h) inside the capacitor as a function of height h. take the potential at the bottom plate to be zero. express v(h) in terms of e and h. v(h) =

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
