Answer:
2123.55 $/hr
Explanation:
Given parameters are:
KV
L = 143 km
I = 500 A
So, we will find the voltage potential provided for the city as:
kV
kV
Then, we will find dissipated power because of the resistive loss on the transmission line as:
W
Since the charge of plant is not given for electric energy, let's assume it randomly as
Then, we will find the price of energy transmitted to the city as:
$/hr
To calculate money per hour saved by increasing the electric potential of the power plant:
Finally,
$/hr
The amount of money saved per hour = $/hr
Note: For different value of the price of energy, it just can be substituted in the equations above, and proper result can be found accordingly.
There are two things that you should remember while dealing with the "Lever Mechanical Advantage" problems:
1) The Effort Arm;
2) The Resistance Arm.
Some books label the Effort Arm as in-lever arm and the Resistance Arm as out-lever arm. (Physics Jargon that you need to remember in order to solve problems)
The Effort Arm is that "part" of the lever where the force can be applied. The Resistance Arm is where some mass is placed. In the diagram, as you can see, the mass is placed on one arm of the lever. Therefore, it is the Resistance Arm.
Now the formula for the "Mechanical Advantage(MA)" is:
Where
is the length of the Effort Arm(the subscript "e" stands for Effort), and 
stands for the length of the Resistance Arm(here "r" stands for Resistance).
Plug in the values:
= 15m.
= 7m.
Therefore, / = 15/7 = 2.143 = MA
The correct answer is option C(2.14).
