a) 3 Watts
b) 10 Watts
c) 300 Watts
d) 3,000 Watts

Answer 1

The average power output is 3 Watts.

Step-by-step explanation:

The average power output can be calculated using the formula:

Power = Work / Time

In this case, Sarah has done 30 J of work in 10 seconds. So, the average power output is:

Power = 30 J / 10 s = 3 Watts

Therefore, the correct answer is Option a) 3 Watts.
