Two cars, with u. l.m. (uniform line movement), travel the road according to the following tables of values: a) Graphically represent the two movements in the same reference system.
b) Which of the two has greater speed?
c) What is the speed of each of the cars?

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).
