HELP ME ASAP A patient in the hospital is undergoing testing. The patient's brain is sending electrical signals to motor neurons, but the muscles are not moving in response. What could be a likely cause for this? Explain your answer using complete sentences.

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
