Aheat pump has a coefficient of performance that is 60% of the carnot heat pump coefficient of performance. the heat pump is used to heat a home to 24.0°c during the winter with the low temperature reservoir at the outdoor temperature. at which outdoor temperature would it be more efficient to add the energy directly to the interior of the home than use it to run the heat pump? -154°c -40.0°c -4.00°c -83.4°c -25.2°c

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
