Question

Which unit does not measure power?
a) N∙m/s
b) J/s
c) N/s
d) W

Answer 1

The incorrect unit for measuring power is N/s, as power is measured in units like W, N·m/s, and J/s (all of which equate to watts).

Step-by-step explanation:

The unit that does not measure power is c) N/s, which is a measure of force applied over time, not power. The units that do measure power are a) N·m/s, which is equivalent to the watt (W), b) J/s, which is the definition of watt, and d) W, which stands alone as the unit of power. Power is the rate at which work is done or energy is transferred, and in the SI system it is measured in watts, where 1 W = 1 J/s (one Joule per second).
