A parallel-plate capacitor has a capacitance of c1 = 5.5 μF when filled with air and c2 = 25 μF when filled with a dielectric oil at potential difference of 12 V. Take the vacuum permittivity to be εo = 8.85 × 10-12 C2/(N⋅m2).

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.
