LIGHT SPEED NS FULL

So the integral of Dy upon squirrels of Gy From zero to L. You will improve GT Now we can integrate both sides. Now you can be arranged this and can write us G via bomb squirreled off key by music. Uh, they were on duty, Which is a camera. Can also organize the differential farmers. What do you do? What And the will spread. So the wave speed can begin a square with golf. And from this equation the web spirit at any question, why is it different the spiral out of the uh male Y. Why use the linear mass density events life or the MAs M. Why from the freedom of what and the forces acting on the amendments when it's up wait uh after violence, wife and what Except ancient. So let's consider element their traditions. Since the wire is uh not weightless and it's great is comparable with attention. Yeah, discussion covered the concept of the web speed and the speed is the function of the spiralled of the ancient and the wire upon building. That light travels in one nanosecond as 12 inches. It gives us 11.811 inches rounding up that will give us a distance. Now we want this in inches, so we know that 1 m is equal to 39.37 inches, so 0.3 m times 39.37 inches and 1 m. We know that our units canceled, leaving us with meters four 0.3 m. Yeah, where C is the speed of light trams, the time interval and one nanosecond says one times 10 to the negative nine seconds and this gives us a distance of three times 10 to the negative 1 m. So do you routine where D is the distance traveled? And that's what we want to solve for So that gives us D is equal to see Time's d so loving and what we know. So for uniform motion, we know that speed is equal to the change in distance over the change in time. We know that one nanosecond is equal to one transformed the negative nine seconds. So we're given that the speed of light, which we call C, is equal to three times 10 to the 8 m per second. So this problem were asked how far light travels in one nanosecond and to give our answer in inches.

So that would give us at full 0.0 all full time. I'm just slopping it basically saying that is in one seconds the lightweight for both, three time tending the eight meter. Instead of saying, leader for seconds, I went with the seconds right there. So three time tend to the aid right meter per second's not. What? Giving 12 kilometres so pretty much exchange phenomenally meter and they use the speed of light to get us time. Okay, so when we go back in a little bit, talk about speed of light speed of light is three kind under the eight meter per second's notice. So it's asked us to use the speed of light. The Speedo like is the same in the cables as the same in a vacuum. How long is take for signal to trouble that distance, so again, is looking for time. Bobby said fiber optic cables is a 12 kilometer e lank. So it's gonna be equal to 2.3 time tended a 20 who's now let's continue and do the next part B. So, um, safe ex wives, you can keep it to decimals. So this will get asked to 100.3 time 10 to the 20. Well, again, if you want to use a multiplication, make sure you put apprentice see around them so that you don't get yourself confused in a calculator.

Delighted by 1.3 time, 10 to the negative. So let's go ahead and calculate at three times 10 to the eighth. Or you can also call this ass huh's same thing.

Now I noticed me the Wiccans All you cannot get at one of those seconds. That's more there me we write this 1.3 times 10 to the negative 12 meter. What about Blunder in this case would get at 1.3, they said. Lambda C is three times 10 to the eighth unit. Lender knew to look for the new, which is frequency. Or you can write the other way around and say one meter is 10 to the ninth. One nano meter is 10 to the nine needed, and I meter. Uh, we're friends into frequency on frequency to weigh Flint's type. You want to have a fiber Waveland transmission of this and what is the frequency? So again we'll convert Improvement. So for this question, up this optical favor first restoration fascinators.
