Which motor performs more work in the same amount of time- a 10 kW or a 20 kW motor? Explain your reasoning.
Power masures work per unit time and kW is a way of measuring it. That should make the correct answer obvious.
To determine which motor performs more work in the same amount of time, we need to compare the power ratings of the motors. Power is the rate at which work is done or energy is transferred, and it is measured in watts (W) or kilowatts (kW).
In this case, we are comparing a 10 kW motor and a 20 kW motor. The power rating represents the maximum amount of power that the motor can produce. The higher the power rating, the more work the motor is capable of performing in a given amount of time.
Therefore, the 20 kW motor performs more work in the same amount of time than the 10 kW motor. The higher power rating indicates that the motor has a greater capacity to do work and transfer energy, making it more powerful.
