Answer:
A symbol and a model are both examples of a representation because they are presented in place of the real thing.
Explanation:
A symbol is a sign, a letter, mark, token, figure, or image used to stand in place of an object, function, or process. For example, co2 is used in Chemistry to represent carbon dioxide. There are many symbols representing other objects or meanings. Mathematically, we can state that "a" equals 40. "a" is a symbol representing the numerical value "40." Similarly, a model is a representation of a structure or a person on a smaller scale. For example, Architects produce models of buildings and other projects that they design.
Answer:
Explanation:
From the question we are told that
Wind speed
Turbine blade diameter 
Air density 
Mechanical energy 
Generally the power generation potential of the wind turbine X is mathematically given as
Where
Therefore
Answer:
0.54 sec.
Explanation:
The Speed: <u>2.4 m/seconds</u>
The Distance: <u>1.3 m</u>
So time = Distance/Speed
Time = <u>1.3 / 2.4</u>
THE ANSWER WILL BE 0.54 seconds.
