lina2011 [118]

Answer:

2 Hz.

Explanation:

Frequency is simply defined as the number of appearances of a periodic event occurring per time. It is usually measured in cycles/second.

vodomira [7]
Hey there,

Your question states: <span>A sailboat moves north for a distance of 10.00 km when blown by a wind from the exact southeast with a force of 2.00 × 10^4 N. The sailboat travels the distance in 1.0 h. How much work was done by the wind? What was the wind’s power? Your response should include all of your work and a free-body diagram

So by doing this, we do the force x</span>'s the work. 

P = e4*10

We would divide this by . . .

3600s

P = e4*10 ÷ 3600s

Your correct answer would be . . .

55.56w

Hope this helps.
