Answer:
b. J/s
Step-by-step explanation:
Remember that a Watt (W) is a unit of power in the International System of Units. It is the electrical unit for the rate at which energy is generated or consumed. A watt is equal to a joule (J) of work performed per second (s).
This means that if you buy a lightbulb of 60 watts, it requires 60 watts per second to function.
