Answer:
early adopter
Explanation:
early adopter means a person who used company or organization new and innovative product, goods and technology before the usage of other customer. so in this case Fred is early adopter who evaluate each products before adopting and common use.
The kinetic energy of the air travelling at 20m/s, which passes through
the circular area in 1 second is 5.4 x 10⁵ J.
What is kinetic energy?
The kinetic energy of an object is associated with its motion. It can be related to the mass and velocity as
K.E = 1/2 mv²
Given the wind is blowing directly towards the wind turbine at a speed of 20 m/s. At this wind speed, 7500 kg of air passes every second through the circular area swept out by the blades.
Substitute the values, we have
K.E = 1/2 x 7500 x (20)²
K.E = 15 x 10⁵ J
Hence, the kinetic energy of the air travelling at 20m/s, which passes through the circular area is 15 x 10⁵ J.

<u><em>[NOTE: THIS IS AN INCOMPLETE QUESTION. THE CMPLETE QUESTION IS: the wind is blowing directly towards the wind turbine at a speed of 12 m/s. at this wind speed, 7500 kg of air passes every second through the circular area swept out by the blades. Calculate the kinetic energy of the air travelling at 12m/s, which passes through the circular area in 1 second.]</em></u>
I would be inclined to think that it's his average speed, because he's traveling a distance over a certain time interval.
hope this helps, Loading000! :-)
That doesn’t make sense can you uhh explain it again
