Question

4. Which of the following statements is true? (1 point)

a. To increase power, you can decrease the amount of work you do in a given amount of time, or you can do a given amount of work in less time

b. To increase power, you can decrease the amount of work you do in a given amount of time, or you can do a given amount of work in more time

c. To increase power, you can increase the amount of work you do in a given amount of time, or you can do a given amount of work in less time.

d. To increase power, you can increase the amount of work you do in a given amount of time, or you can do a given amount of work in more time

Answer 1

c. To increase power, you can increase the amount of work you do in a given amount of time, or you can do a given amount of work in less time.

Explanation:

• Power in physics is defined as the rate of energy is being transferred over a particular time. The rate or amount of energy transfer is the work done to an object whereas  it is in a specified time.
• The formula to find the power is $Power = \frac{Work}{Time}$ , Hence, to increase the power in a given system either you have to reduce the time by increasing the work or increase the amount of work in the given time.
