<span>Wind farms are composed of tens of wind mills that us electric generator to harness the power of the wind. The power that comes out of the electric generators should be proportional with the force or the wind which is also proportional to the speed of the wind. Considering that a 10 m/s generates 500 kW, than a 12 m/s wind should generate somewhere around 600 kW.</span>
Ans : 2(-2)-3(3)-(-2) = -11
Answer: r≈7m
Step-by-step explanation:
Good morning,
Answer:
<h2>the number of true false questions : 6</h2><h2>the number of selected response : 4</h2>
Step-by-step explanation:
Let x represent the number of true false questions
and y represent the number of selected response
we have to solve this system to work out the number of each type of question
x+y=10 (1)
2x+3y=24 (2)
(2) - 2×(1) ⇒ y=4
now ,we replace y by 4 in equation (1)
x = 10 - 4 = 6.
