When using a series circuit to connect four small light bulbs, which statement is most accurate?

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

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).

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge
