1.) joule
2.) watt
3.) horsepower
4.) feet-pounds

Answer 1

watt

Step-by-step explanation:

horse power is used for cars, joule is used for energy or power and feet pounds has nothing to do with house hold appliances.

Answer 2

The answer is Watt

Step-by-step explanation:

Power is the rate at which energy is used. The unit of power is the watt , which has the symbol W. For example, a 20 W electric lamp uses 20 J of electrical energy every second to stay alight. The meters that are installed at our homes for electrical usage measures power in kilowatts. So we can say that option 2 is the correct answer.
