Question 1 Report

Which of the following units is equivalent to the watt?

Answer Details
The unit of power is the watt (W), which is defined as the rate at which work is done or energy is transferred. In terms of fundamental units, power can be expressed as the product of force and velocity, which can be further expressed as mass times acceleration times velocity. Simplifying this expression, we get the unit of power as kgm2s-3, which is option B.
