Amolniya orbit is a highly eccentric orbit of a communication satellite so as to provide continuous communications coverage for scandinavian countries and adjacent russia. the orbit is positioned so that these countries have the satellite in view for extended periods in time (see below). if a satellite in such an orbit has an apogee at 48,000.0 km as measured from the center of earth and a velocity at apogee of 3.7 km/s, what would be its velocity (in km/s) at perigee measured at 740.0 km altitude? (enter the magnitude.)

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.
