For points far from the ends of the cylinders, determine the electric field at a radial distance r from the central axis of 2.2 cm .

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

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.
