Answer

  1. Power generated decreases
Explanation:
Power is the rate of energy generation(or absorption).
The relation between time and power is ${ P} = \frac{E}{t}.$
So power and time are inversely proportional to each other. Hence when the time to complete a given amount of work increases then the power generated decreases.
