Hi, everyone In this problem, it is given you remember, the battery is to Elwood, and interest rates is white. Forum heat dissipated in the Rs 80. Vote power is Kurt to buy Squarer and current supplied by the battery will be. So it is to be e square are over art, plus our holy square from going into Oh, so it can be written as our square place to our in toward minus e square are or what? Big? Yes, Ari Squire is continue. Yeah. Yeah. We can write our square blessed to our into our e square. We are upon people with where we square our upon the that is 18 mhm plus point fold. Yeah, to our square minus r plus 0.1 sixties cartoon hero. So the distance he will that point to it? But that's all. Thanks for

In this problem, I'm writing the reaction. Just look at it carefully. Any energy for at be your ford four H two will react to form any and at four at people for plus four as to and and ME energy for add bill for will react to form and the beauty plus an STD plus as to So according to the option. In this problem option. See each correct. Was there not that we have any Beauty which reacts with metallic oxide to give colored or to post fails.

Hello, everyone. Today we're going toe. Consider the following problem. 25 centimeters long metal rod is placed on the ex wife plane and it makes 36.9 degrees. Well, er the x axis and 53.1 with the why excess So throw the pictures. So why X and our And this this angle EEZ 36 nine. And this angle is 50. 53 0.1. And the question is, should we should we should find l a dramatic force induced in the road. Youth, it is moving with the consul velocity along the X axe is access B equals 6.8 meters per second. Seeks coined eight in the magnetic field. In this space he's you and I'm here in any work victor form. So this is a projection on eggs. So there should be I'd should be j there should be kay. Right? Uh so let's concede there the simple case, which is also shown in the chapter. So let's be OK to do time. Eso Let's consider a road. Sorry, Brooke did let me go. Cane are always signal. He's okay. Uh so I hope you do We work this time So anyway, we have. You would? Yeah, that's better. And this thing is ruling with hello city or we'd its length is l Please. No, in the vanity feelings be, which is perpendicular. Uh oh. He's playing off motion. So let's say it's, um, come going in tow in tow. Play his magnetic field. Then there is a formal which tells that and primitive force induced a cursed uh, the road would be seem clean. Uh, B V up. This is for more from the book for the front of the reference, Um, I don't It's number. So in 29.6 yeah, and let's see how it is divided. So find them until my name is low. He's far. They slow. Which tells us how can we calculate Erica Motive forces? In any case, so far, these low else us everything right. Sorry. Um, I'll get this. Fine. Let me write absolute here, huh? And the absolute here is well minus Delta fee change in flax over time. Delta T, where does Aziz into infinity? Similarly small. But the question is, what's the flax here? Because we don't have a loop here. Right. Um, but two flags. He's considered here between knew and all the positions off the road. So let's say the road wounds after time D t it goes here. Uh, displacement. Yes, B dt. Does this place mean these the d t X lividity? Right. And we're seeing that thes tell tiffy these plaques in this rectangle. So it is simply it is like saying that, uh, how much flour How much feel lines with these roads across in the time period. So this would be Let's keep minors be B e t and l right, because me cock with flax and plaques, ese be not too played by the every area and bees uniforms, right? Do you write my DP and DT can strokes? DT is cancelled out and we're left with minus B v l and his miners just tells us, um, the direction off. These are little motive force. And let's go back to our problem, which is very similar to days way will see the differences so resentful. I just like to mention So we just need to enter this Z axis. Uh, but we have two options. As we know, we can use either left handed or right handed systems accordion systems. So I would use, um, left handed. Um, but you can don't anyways, you any way you want because it's a problem. Doesn't specify use on the space city. Oh, cease to right. Uh, so let's z axis ti thes going into in tow. Uh, plane that would be left hand. And if if I have chosen see coming out from this plane, it'll be the right hand. So doesn't have much meaning. Doesn't give us, like, defense. Real difference. So this easy. And now let's just throw this picture here again. So we have a road. It's morning with the well, our city And is we So we only need in order to calculate electro motive force, we only need to consider the projection off the field, which is, uh, perpendicular off the plane of motion. We just need to consider to be Z, and as we see here, BZ is minus on. I see your point 09 whatever. And yeah, this other projects projections doesn't contribute. And this right down this formula we have derived. So, Absalon, he's, uh let's forget about sine minus and just, uh, find out that's what Wilder So Absalom would be. You can say absolutely absolute. While you're Absalom would be easy. The let's say Ellis lengths Just 25 cents. But ah, is this right? No, because we're missing something. Right? Because we can simply compare In Syria, something's different. In this case, the difference is the direction off. Uh, well, Lucy T it makes some angle, so it is not perpendicular to the word, so we just need to consider it They make a projection on the perpendicular exists here. Um and this angle would be 50 50 sweep point. What? Any friend that miss taken. You can double check. Uh, e Yeah. These things angle is 30. Uh, certainly a 6.9 in this one would be gives his three. So he wrote there because it doesn't look like 53. Uh, looks like less on the picture, but we get the idea. Right. So there should be causing Steve. There's 3.1, and you can check also and Deasy's point seal for 09 for, like, something like this Rock. Right? So it is no answer off. Uh, the first question and second question just We just don't need toe being rounds. Where is the highest potential, which ain't his the highest higher potential. So for this reason, they just consider it. And Electra, um, inside this metal, it isn't a negative charge, as we know. And while it's moving with the road because the same Willow city And while it's in the field, uh, in the magnetic field, then do you Lawrence Force would rise right in Florence minus mmm. Because be Oh, I missed Mike's because it's an elegant to eat his, uh, negative church. And while, uh, I chose, uh, Z axis like these. So the exes is going inside the plane, then, uh, and ease you in Like these, uh, says this. It has negative projection of Z. That means that be is coming out from the plane in little. Consider what's the four. Was the direction off this force? Uh, on the election. Uh, so what would be V? Crosbie here? Me is this Victor and B is coming out off the plane, and if you use, uh, right and rule in a twist, uh, our four fingers, uh, from V to be so And look at the direction where Oh, my Sam looks so it looks down, but while there is minus. So it would sleep to force up and total direction off the force would be Oh, right. Uh, because B is looking down, right? And why there's my minus. Then it would sleep. Yeah, that that What does it mean? That means that old ***, too, charges I tend to go and together here and, uh, at the upper end. So there would be mines. And while in the beginning Ah, the charges are equal distributed and total charges zero. And then suddenly, editors would go up. That means that here there would be plus stranded music. Oh, below. Uh, hand has higher potential, then our perp. So it's a question on its answer. Quit question. Yeah. And then see, Thank you.

Here we have Omega Te's 135 dignity, which is 25 radiant over 3. 60 degree. It was It's 34 by so Oh my God, he's three pi over four divided by do May The second it was 1178 Ready in per second.
