The interior of a refrigerator has a surface area of 2 m². it is insulated by a 4.6 cm thick material that has a thermal conductivity of 0.024 j/m·s·◦c. the ratio of the heat extracted from the interior to the work done by the motor is 8.7% of the theoretical maximum. the temperature of the room is 33.6 ◦c, and the temperature inside the refrigerator is 0.6 ◦c. determine the power required to run the compressor.
