Wind turbines generate electricity by following a simple principle. Moving wind transfers energy to the blades of the windmill, which results in spinning of the blades. These blades are connected to an internal shaft which also starts spinning. This spinning of the shaft generates electricity, which is further distributed to electrical substations to provide electricity to homes and businesses.
What is a wind turbine?Wind turbines work by creating kinetic energy when the power of the wind makes their blades spin. This kinetic energy is converted into electrical energy.
Thus, the steps describing how a wind turbine functions are,
Step 1: Wind moves the blades of the turbine.
Step 2: Internal shaft spins
Step 3: Generator produces electricity
Step 4: Distribution lines carry electricity to substation

Convert the following complex number into its polar representation -4i
The expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)
What is complex number?A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of number is written together. For example,
a+bi
Here, (a) is the real part while (b) is the imaginary part.
The complex number which need to convert into its polar representation is,
n=-4i
It can be rewritten as,
n=0-4i
The radius r of the polar form is,
r²=0²+(-4)²
r²=0+16
r=4
The value of cos theta is,
tan θ=0/-4
θ=tan⁻¹(0)
θ=π
Thus, the polar form is,
z=rcos θ+(r sin θ)i
z=-4(cos π+ isin π)
Thus, the expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)

Which expression represents the volume of the prism? 10x3 cubic units 15x2 cubic units 20x3 cubic units 30x2 cubic units
The expression that represents the volume of the prism is 30x² cubic units.
Option D) is the correct answer.
What is a prism?A prism is simply a solid geometric with two polygonal faces laying in parallel planes and with the other faces parallelograms.
Volume of a prism is expressed as;
Volume = base area × height
Also, the base area is expressed using the area of a trapezoid.
Hence,
Base area = (1/2) × h( a + b )
Now, let;
h = xa = xb = 2xBase area will be;
Base area = (1/2) × h( a + b )
Base area = (1/2) × x( x + 2x )
Base area = (1/2) × 3x²
Base area = 3x²/2
Now volume will be;
Volume = base area × height
Volume = 3x²/2 × h
So, let h be 20 units
Volume = 3x²/2 × 20uniit
Volume = 60x²/2
Volume = 30x² cubic units
Therefore, the expression that represents the volume of the prism is 30x² cubic units.
Option D) is the correct answer.

Which system of equations models the paths of the two skaters? y = 0.08x2-1.6x+13 and y = 0.08(x-10)2+5 y = 0.08x2-1.6x+13 and y = 1.6(x-10)2+5 y = 0.08x2-1.6x+13 and y = 0.8(x-10)2+5 y = 0.08x2-1.6x+13 and y = 5(x-10)2+5
The system of equations models the paths of the two skate is y = 0.08x²-1.6x+13 and y = 5(x-10)²+5. The correct option is b.
What is quadratic equation?The equation with second degree of an unknown variable x, y, m, n, or p is called the quadratic equation.
David starts at (20, 13) and skates along a path that can be modeled by a quadratic equation with a vertex at (10, 5).
Vertex form of quadratic equation is
y =a (x -h)² +k where (h,k) is the vertex.
We plug in (10,5) for h and k
y= a (x -10)² +5
Now plug in (20,13) in the above equation and find out 'a'
13 = a (x -10)² +5
13 = a(10)² +5
13 = 100a + 5
Solving for a, we get
a = 0.08
Substitute 0.08 for 'a' then the equation becomes
y= 0.08 (x -10)² +5
Thus, the correct option is b.

Explanation:
How many grams of calcium oxide will be produced in a closed vessel containing 20.0 kg of calcium and 20.0 kg of oxygen gas if the reaction goes to completion? (atomic mass of calcium = 40.1 amu)
Answer:
Explanation:
The mass of Calcium oxide that will be produced in a closed vessel is 27984.1311 g. The Number of moles is defined as given mass over molar mass.
Calculation of Number of moles:
Number of moles = Given mass / Molar mass
For Calcium :-
Mass of calcium = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of calcium = 40.078 g/mol
Thus,
Number of moles = 20000 g / 40.078 g/mol
Number of moles = 499.02 moles
For oxygen gas :-
Mass of oxygen gas = 20.0 kg = 20000 g ( 1 kg = 1000 g )
Molar mass of oxygen gas = 31.999 g/mol
Thus,
Number of moles = 20000 g / 31.999
Number of moles = 625.19 moles
According to the given reaction:
2 moles of calcium reacts with 1 mole of oxygen gas
Also,
1 mole of calcium reacts with 1/2 mole of oxygen gas
So,
499.0269 mole of calcium react with mole of oxygen gas
Moles of oxygen gas = 249.5135 moles
Available moles of oxygen gas = 625.0195 moles
Limiting reagent is the one which is present in small amounts. Thus, calcium is limiting reagent.
The formation of the product is governed by the limiting reagent. So,
2 moles of calcium produces 2 moles of calcium oxide
So,
1 mole of calcium produces 1 mole of calcium oxide
Also,
499.0269 moles of calcium produces 499.0269 moles of calcium oxide
Moles of calcium oxide = 499.0269 moles
Molar mass of calcium oxide = 56.0774 g/mol
Mass of calcium oxide = Moles × Molar mass = 499.0269 * 56.0774 g = 27984.1311 g
27984.1311 g of calcium oxide will be produced.

A human rights violation is the disallowance of the freedom of thought and movement to which all humans legally have a right. While individuals can violate these rights, the leadership or government of civilization most often belittles marginalized persons. Abductions, arbitrary arrests, detentions without trial, political executions, assassinations, and torture often follow. In cases where extreme violations of human rights have occurred, reconciliation and peacebuilding become much more difficult.

A random drawing will determine which 3 people in a group of 9 will win concert tickets. what is the probability that you and your 2 friends will win the tickets? express your answer as a fraction in simplified form.
The probability that you and your 2 friends win the tickets is P = 1/84.
How to determine the probability?
There are 9 possible outcomes, 3 of which are you and your friends.
All of these outcomes have the same probability of being randomly selected, then the probability of winning is given by the quotient between the number of "outcomes" that you have and the total number of outcomes.
Let's say that the outcomes are pieces of paper with the names of the participants.
First draw:
In this one, there are 3 possible options that work, one is your paper, and the other two are for your friends.
So the probability is 3/9 = 1/3.
Second draw.
One of your group already won, so now there are 2 of you, and a total of 8 pieces of paper, so this time the probability is 2/8 = 1/4
Final draw:
Only one of you remains, and there is a total of 7 pieces of paper, this time the probability is 1/7.
The joint probability (of these 3 events happening in succession) is given by the product of the individual probabilities:
P = (1/3)*(1/4)*(1/7) = 1/84
