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>
The answer to your question is Sheeps.
This is because the plural of sheep, is still sheep.
Ex. There are 5 sheep on my farm.

The answer is c. process.
Explanation:
Psychologists Richard Atkinson and Richard Shiffrin described memory as a process, meaning it goes through a series of steps. They described three systems:
- Sensory memory, which is only stored for a fraction of a second, and relies on sensorial input;
- Short-term memory, which stores <u>processed</u> information, but might disappear after a few seconds; and
- Long-term memory, which may retain information for a lifetime.
A variation of long-term memory is called working memory, holding information that can be manipulated.
