Answer:

200 W

Explanation:

The power is given by the ratio between the amount of work done and the time taken to perform the work:

$P=\frac{W}{t}$

where in this problem we have

W = 2600 J is the work done

t = 13 s is the time taken to do the work

Substituting the numbers into the equation, we find

$P=\frac{2600 J}{13 s}=200 W$

Answer:

200 W

Explanation:

To figure out the power, you need to use the formula: P = work/time<em>. You need to remember that they may ask you for the significant figures, so that is how many digits you have to round by. This question does not specify significant figures.</em>

<em>2600/ 13 = 200 </em>

Your answer is 200 watts
