Final answer:
The correct statements are A, B, and C. Statement A is true because the SI unit of power is the watt, and power is indeed the rate at which work is done. Statement B is true because a person is limited in the total work they can do by the rate at which energy can be transformed. Statement C is true because power is indeed the rate at which energy is transformed. It measures how quickly energy is converted from one form to another.
Step-by-step explanation:
(A) The SI unit of power is the watt. Power is the rate at which work is done.
(B) A person is limited in the total work he or she can do by the rate at which energy can be transformed.
(C) Power is the rate at which energy is transformed.
(D) A person is limited in the total work he or she can do only by the total energy required.
(E) The SI unit of power is the horsepower.
The correct statements are A, B, and C.
Statement A is true because the SI unit of power is the watt, and power is indeed the rate at which work is done.
Statement B is true because a person is limited in the total work they can do by the rate at which energy can be transformed. This means that even if a person has a large amount of energy, if they cannot transform it at a fast enough rate, their work will be limited.
Statement C is true because power is indeed the rate at which energy is transformed. It measures how quickly energy is converted from one form to another.
