How are a symbol and a model both examples of a representation?
viva [34]

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.

At a certain location, wind is blowing steadily at 10 m/s. Determine the mechanical energy of air per unit mass and the power ge
Effectus [21]

Answer:

X=3976.078202kW \approx 3976kW

Explanation:

From the question we are told that

Wind speedV_w=10m/s

Turbine blade diameter D=90m

Air density  \tau=1.25kg/m^3

Mechanical energy K.E =0.05kJ/kg

Generally the power generation potential of the wind turbine X is mathematically given as

  X=m'*K.E

Where

m'=\tau *\pi*D^2/4*V

m'=1.25 *\pi*90^2/4*10

m'=79521.56404kg/s \approx 79521.5kg/s

Therefore

X=m'*K.E

X=79521.56404*0.05

X=3976.078202kW \approx 3976kW

X=4.0MW
