Solution 1
Power is the rate of work, and it is calculated as work divided by time. This means that power is a measure of how quickly work can be done. The unit of power is the Watt (W), which is equal to one Joule per second. In a physical context, to calculate power, you would need to know the amount of work done (in Joules) and the time it took to do that work (in seconds). The formula for power is P = W/t, where P is power, W is work, and t is time.
Solution 2
Power is the rate at which work is done or energy is transferred. It is calculated by dividing work by time. So, the correct answer is d. Power is the rate of work, and it is calculated as work divided by time.
