Would it would be easier to measure parallax to a nearby star from the planet Jupiter (5th from the sun) or from Venus (2nd from the sun). Explain.

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
