Explanation:
The correct answer to the above question is as follow -
1. The power is defined as the work done per unit time. The unit of power is Watts and is proportional to the mass of the body.
- Therefore, the power is more for the body of more weight. So if a person of 40kg and a person of 75kg run up the stairs at the same time, then the person of weight 75kg will develop more power.
2. Power is equal to the work done by the body per unit of time. For one second, work done will be 1000 joule. So, if the bulb of the power output of 1000 Watt, work done is 1000 joule in one second.
3. Horsepower is a unit of measurement of mechanical power that is roughly equivalent to about 746 Watt of energy. But it has nothing to do with horses or any animal in general. So on average, we will develop the power of 0.7 Watt during intense activity.
