Final answer:
The Newton is not a unit of power; it is a unit of force. Power is measured in watts, and other units like horsepower and volt-ampere also represent power.
Step-by-step explanation:
The unit that is NOT a unit of power is d.) Newton. Power is defined as the rate of doing work or the rate of energy transfer. The SI unit for power is the watt (W), which is equivalent to one joule per second (1 W = 1 J/s). Other common units of power include horsepower (hp), where 1 hp equals 746 W, and volt-ampere (VA), which is also a unit used to measure electrical power and is equivalent to watts in the case of direct current (DC) circuits. However, the Newton is a unit of force in the International System of Units (SI), not power. It measures the force required to accelerate a one-kilogram mass at a rate of one meter per second squared (1 N = 1 kg · m/s2).
