In this problem, just look at it carefully. BB I too, will react in pageants of BSE here, too. ECU was to give compound Are we change which aid 80 cl here, which it A d c L. Here? So this is white PPT. They said white PPT. Therefore, according to the option option, age, correct and said for this problem, A d c l a will be the white PPT in this problem.

58 9 seconds equals 58 times gentle negative. Nine. Second It was 5.8 times two ended up native eight second, 0.0 for six. Giga second equals zero point 046 times, 10 to the nine second. It was 4.6 times 10 to the seven second 97 to 0. May the second comes out to be 97 to 0. There's gentle, dark negative. Three second equals 9.72 second 12.3 que those second it was to a 0.3 10 to the three second. It was 1.23 times into the four second.

So never work on Problem fifty eight from Chapter one. This problem here assessed. Convert. Ah, several units carry out some really conversions. So has going to start with parquet where were asked, convert a value and inches two millimeters, so the value that were given has zero point one zero five inches. So right away we can convert from inches to centimeters by multiplying by two point five four and then we can convert from centimeters two millimeters by multiplying by ten, because senti is ten to the minus two and Milly is ten to the minus three, so there's only a factor of one between them. So the value that we get here when we do our multiplication, you can see first, the inches will cancel and centimetres will cancel in the value that we get is two point six seven millimetres. The second conversion were asked to do is from miles two meters in the value that were given a zero point zero five five zero miles. And so first we can convert defeat by multiplying by fifty to eighty than two inches by multiplying by twelve, then two centimeters by multiplying by two point five four and then finally two meters by dividing by one hundred. So Miles cancels feet, cancel inches, cancel centimeters cancel and the value that we get an idiot point five meters. What in part C, whereas convert micro meters per second, two kilometers per hour, so value that were given his eight point seven five Micra meters per second. So first let's comfort micro meters, two kilometers and first we can convert from micro meters two meters by dividing by ten to the sixth and then two kilometers bye dividing by ten to the three or one thousand. We could combine these first two steps here by simply putting dividing by ten to the nine. Then we converse seconds to hours, sixty seconds for every one minute and then sixty minutes for every one hour. We can go ahead and cancel micro meters, micro meters, meters, meters, kilometers. Sorry we don't cancel Kilometers Colome Er's is our final distance unit. We can come to Seoul seconds and it's that and the value that we get is three point one five times ten to the negative five kilometers. Hurry now. So for part D, whereas to convert from meters cube two yards Cube. So here do our similar conversion. We just remembered a cube, all of our multipliers. So one point nine nine five five we can convert this two centimeters by multiplying by hundred huge. That's equal to one meter. Cute and two inches where dividing by two point five four again end cute then too feet by, dividing by one twelve inches cute and then finally two yards by dividing by three feet cubed since there are three feet and one yard. And when we do this here we get seven point six seven one yards, cute for Part IV, whereas to convert dollars per pound, two dollars per kilogram. So here we have three point nine nine dollars per pound. So we simply need to convert between pounds and kilograms here so we can put one pound. It's equal to zero point four five three six Mr number here to your point four five three six kilograms. And when we do this multiplication, we get eight point eight zero dollars for a kilogram and then four part F. We're asked to convert from pounds cubic feet, two pounds, two grams per Miller leader. So they were given his eight point seven five pounds. Perfect you. So first we can convert from pounds to kilograms with same unit. We just used zero point four five three six kilograms is the same as one pound and now we can convert acute milliliters first. Excuse me. We're not converting two kilograms. We're converting two grams so a thousand grams is equal to one kilogram. Then we can convert feet cubed two middle leaders by first Khoumba converting to toe inches So one feet cubed is twelve inches cute and then we convert to centimeters. One inch cubed is equal to two point five four centimeters cubed. Then we recognise that one centimeter cute is the same as one ml. So we can cancel pounds pounds, kilograms, kilograms Be cute and she's cute Centimetres Cube And we're left with units of Gramps, Perma leader. And we do be calculation to get zero What? One four zero grams her and no

All right. Question 11 asks to convert the following record speeds so that they're in miles per hour, kilometers per hour and meters per second. So if the party ritual the Australian dragon fly, I can fly surprising at 36 miles per hour. So start with this one. It's a freezing here and we want every one of these speeds again. Miles per hour climbers, power and meters per second. So for party, Amy want first good informers per hour. So we start with 36 miles per hour. Our time unit miles. We don't want to change, but we need to change. Um, our distance measurement miles, We know that that means we need one mile in our numerator started denominator many kilometers on top. But we know that since miles are bigger than commoners, there are 1.609 kilometers per mile to double check our miles units cancel out and we're left with kilometers per hour. I finally answered It's 57.9 kilometers per hour. Great. Um, do you know though, however we do start with 36 that's two significant digits or finance or should be to Israel. That's 58 kilometers per hour. All right. And finally you need this and meters per second miles. So miles per hour. Sorry, I'm jumping the gun here. We wanted to heavy in meters per second, something we found in the first line. We saw that there's 1.69 kilometers per mile. Sophie multiplied by 1000. Know that there's one that 1609 meters per mile for one mile. It's a real love with meters per hour. So then you cancel our hours about seconds of the denominator. So one our top and 3600 seconds on the denominator so that just to check our units, um, are miles Cancel out our hours cancels out and we are left with meters per second. Which two significant digits would result in the distant, uh, velocity of 16 meters per second? That's part a part B. A similar idea, starting from starting with plumbers per hour. Excuse me. We bring in miles per hour and, um, meters per second. First we know that, Mommy. Okay, so live miles per hour first. So what? Miles on our new minor one mile again is 1.69609 Come on, Butters! Commers did it cancels out. We're left with miles per hour. Perfect! Let me get this time 23 significant digits because we're starting with three, we get a velocity of Syrian yet 217 miles per hour. This confused because it was very fast. But again, we're dealing with records here and I should know that this is the diving peregrine falcon. Speed is 304 young kilometers. Incredible! So that's the 1st 1 I'll do the 2nd 1 decided this time just so I have the room. So now we're going to meters per second, starting with 3 49 kilometers per hour to go from kilometers, two meters. You know that they're 1000 meters within one kilometre, canceling out a kilometer unit and read seconds. So you know that in one hour there are 3600 seconds again double checking your MRI. It's kilometres cancels own hours, cancels out and we do have meters per second as our unit and we find that this philosophy again 23 significant digits is 96.9 meters per second. Awesome! In part three, sir Curtsy! The Lockheed s R 71 jet aircraft travel about three times the speed of sound in 980 meters per second. Crazy so we can convert meters per 2nd 1st thing we'll do is to go to accomplish parameter. So like we said before any one kilometer, there are 1000 meters in well, hours of the denominators who know that in one hour there are 3600 seconds checking your Edith's, uh, hours fine, but HR. But still our seconds cancels meters cancels and we are left with kilometers per hour. We find this time to two significant figures because 9 80 has two significant digits here. 98 not the zero. Our final answer should represent that as well. We have 3.5 times 10 to the two kilometers per hour and if you calculate that, hopefully will be 35 28. But again, just so we're using the rates significant digits and finally I heard a meters per second is tangled miles per hour. So miles on her numerator one mile hasn't mentioned it party. Here's 1609 meters and in bum again, denominated needs one hour, our new better. There's 3600 seconds again. Just double checking your Eunice seconds. Cancels meters, cancels and you're in love with miles per hammer to two significant digits is 2.2 times 10 to the two two news? Yeah, exactly conducive to yeah, into the three. Excuse me, that's right into the three miles per hour that is the same. This also here should be tended. The three in the first part of the question. Excuse me. It was 3.5% 3 kilometers per hour because there's 3528 and similarly for parts seats 2.2 times 7 to 3 miles per hour.
