Question 4 of 34 How do you add vectors in two dimensions? A. By adding the magnitudes of the vectors B. By lining up the vectors head-to tail, then connecting the beginning of the first vector to the end of the last vector o C. By lining up the vectors head-to-tail, then connecting the beginning of the first vector to the beginning of the last vector D. By subtracting the magnitudes of the vectors su​

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).
