Aneutron star and a white dwarf have been found orbiting each other with a period of 28 minutes. if their masses are typical, what is their average separation? compare the separation with the radius of the sun, or about 0.005 au. (hints: refer to kepler's third law with regard to mass. assume the mass of the neutron star is 2.5 solar masses and the mass of the white dwarf is 0.3 solar mass.)

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.
