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.
It would move slower/ faster by changing the mass, which would effect the weight and speed.

<u>According </u><u>to </u><u>Newton,</u><u> </u><u>the </u><u>bodies </u><u>in </u><u>the </u><u>universe </u><u>attract </u><u>each </u><u>other.</u><u> </u><u>This </u><u>force </u><u>if </u><u>attraction</u><u> </u><u>is </u><u>called </u><u>force </u><u>of </u><u>gravitation</u><u>.</u><u> </u> For example, the earth attracts the moon and the moon attracts the earth too. Similarly, the earth attracts the Jupiter and the Jupiter attracts the Earth.
The effect of force of attraction of a big body on a small body can be observed but that of a small body on a big one cannot be observed. The sun is so large that even the sum of the masses of all its planets and the satellites is only about 0.0015th part of mass of the sun. Due to the gravitational force between the sun and the earth, the earth keeps on moving around the sun. Similarly, the gravitational force between the satellites and planets makes the satellites to revolve around the planets. So, The gravitational force is responsible for the existence of solar system. The effect of gravitation can be experienced more on liquid than solid. Hence, we see tides in the sea and ocean due to the force of gravitation of the moon and the sun on the earth when they lie on the same straight line.

Answer:
a) D_ total = 18.54 m, b) v = 6.55 m / s
Explanation:
In this exercise we must find the displacement of the player.
a) Let's start with the initial displacement, d = 8 m at a 45º angle, use trigonometry to find the components
sin 45 = y₁ / d
cos 45 = x₁ / d
y₁ = d sin 45
x₁ = d sin 45
y₁ = 8 sin 45 = 5,657 m
x₁ = 8 cos 45 = 5,657 m
The second offset is d₂ = 12m at 90 of the 50 yard
y₂ = 12 m
x₂ = 0
total displacement
y_total = y₁ + y₂
y_total = 5,657 + 12
y_total = 17,657 m
x_total = x₁ + x₂
x_total = 5,657 + 0
x_total = 5,657 m
D_total = 17.657 i^+ 5.657 j^ m
D_total = Ra (17.657 2 + 5.657 2)
D_ total = 18.54 m
b) the average speed is requested, which is the offset carried out in the time used
v = Δx /Δt
the distance traveled using the pythagorean theorem is
r = √ (d1² + d2²)
r = √ (8² + 12²)
r = 14.42 m
The time used for this shredding is
t = t1 + t2
t = 1 + 1.2
t = 2.2 s
let's calculate the average speed
v = 14.42 / 2.2
v = 6.55 m / s
Answer:21.97 m/s
