1 Choose two forces and compare and contrast these forces. You must provide two ways that
they are alike and two ways that they are different. You may make a list, write in paragraph
form, or make a chart. The forces are gravity and air resistance

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).
