The average power and instantaneous power become equal if work is done at:
Correct answer: B. Uniform rate
- A. Any rate
- B. Uniform rate
- C. Variable rate
- D. High rate
Explanation
The average power and instantaneous power become equal if work is done at a constant rate. This means that the power does not change over time.The average power is the total work done divided by the total time taken. The instantaneous power is the power at a given instant in time.If the work is done at a constant rate, then the average power and instantaneous power will be equal. This is because the total work done and the total time taken will be the same. Pavg = Pins

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
