Answer:
Explanation:
Wind, solar and hydroelectric systems generate electricity with no associated air pollution emissions. Geothermal and biomass systems emit some air pollutants, through total air emissions are generally much lower than those of coal and natural gas fired power plants.

Pythagorean theorem should be used to determine the length of any of the three sides of a right-angled triangle.
<h3>What is Pythagorean Theorem?</h3>
Pythagorean theorem can be defined as a fundamental mathematical equation in Euclidean geometry and it can be used to determine the length of any of the three (3) sides of a right-angled triangle.
Mathematically, Pythagorean's Theorem is given by this formula:
c² = a² + b²
<u>Where:</u>
<u>For example:</u>
c² = 3² + 4²
c² = 9 + 16
c² = 25
c = √25
c = 5 units.

Your answer is B.) 11x=15
It is important to note that the direct of flow of the electricity current in the Linear Machine is anti-clockwise direction. The resultant effect of this is such that is stand at variance with the change in flux as force is going the right direction. See attached Image (Illustration I).
<h3>What is the magnitude of the current?</h3>
Recall that Force (f) = il xB
Given that Force (F) = 10N; and
Magnetic Field Density B = 0.5T
Hence,
10 = i x 0.2 x 0.5
[Note that Width is converted to Meters from millimeters that is 200 mmm = 0.2m]
10 = 0.1i
i = 10/0.1
i = 100A
<h3>
What is the Induced Voltage Across the metal bar?</h3>
Note that Vg = Vde + IR
Vg = 10 + 100 x 0.05
Vg = 10 + 5
Vg = 15v
<h3>
What is the final speed of the metal bar?</h3>
The final speed of the bar is given as V
Recall that Induced Voltage is VB x L
That is:
15 = V x 0.5 x 0.2;
15 = 0.1 V
make V the subject of the formula:
V = 15/0.1
V = 150m/s
<h3>
What is the status of the Machine? a motor or generator?</h3>
Given that the current being supplied is in DC hence the machine is a generator. [Vdc x i]
<h3>What is the electric power of the source?</h3>
The electric power of the source is:
Vdc x i
= 10 x 100
= 1,000 watts
