The currents (Amperes)
in the two cases are calculated as power/voltage: <span>
510000W / 12000V = 42.5 A
510000W / 47000V = 10.85 A
<span>And that the power wasted in the two cases is calculated as current^2
x resistance:
(42.5 A)^2 (2.5 Ohms) = 4,515.625 W
(10.85 A)^2 (2.5 Ohms) = 294.30625 W
<span>So the amount of power saved is the difference:
<span>4,515.625 - 294.30625 = 4221.32 Watts</span></span></span></span>
<span>This is the main reason
why distribution grids aim to operate at the highest voltages possible.</span>
To solve this there is this website that I found that helps
I am in middle school so I have no idea how to solve this
but
this website may help considering u are in high school and u
(hopefully mind u)
know how to solve this
so to get there u google
"whats impact speed"
and click on the first thing there the website is ehow
Answer:
The first one
Explanation:
The waves on the first image are the highest in frequency meaning they have the highest pitch.
I think you forgot to give the options along with your question. I am answering the question based on my knowledge and research. <span>A business that sells products to teens would most likely create a website with a title ending in .com. I hope that this is the answer that has actually come to your great help.</span>
Something that goes round in circles could have a high speed but zero average velocity.
