Which statement comparing the two swimmers is accurate? It may be necessary to multiply by more than one conversion ratio in more difficult problems. The Celsius and Fahrenheit temperature scales, however, do not share a common zero point, and so the relationship between these two scales is a linear one rather than a proportional one (\(y = mx + b\)). I'm confused. Several other commonly used conversion factors are given in Table \(\PageIndex{1}\). Regardless of the details, the basic approach is the sameall the factors involved in the calculation must be appropriately oriented to insure that their labels (units) will appropriately cancel and/or combine to yield the desired unit in the result. If we have the conversion factor, we can determine the mass in kilograms using an equation similar the one used for converting length from inches to centimeters. \hline \text { Date } & \begin{array}{c} Alternatively, the calculation could be set up in a way that uses all the conversion factors sequentially, as follows: \[\mathrm{\dfrac{1250\:\cancel{km}}{213\:\cancel{L}}\times\dfrac{0.62137\: mi}{1\:\cancel{km}}\times\dfrac{1\:\cancel{L}}{1.0567\:\cancel{qt}}\times\dfrac{4\:\cancel{qt}}{1\: gal}=13.8\: mpg}\nonumber \].

There are 3,600 seconds per hour, or you could even say that there are 3,600 seconds for every 1 hour. We say, well, distance There are 1,000 liters (L) in 1 kL and 1 mc032-1.jpg 106 microliters (mL) in 1 L. There are 12 inches (in.) The diameter of a red blood cell is about 3 x 10-4 inches. Note that this simple arithmetic involves dividing the numbers of each measured quantity to yield the number of the computed quantity (100/10 = 10) and likewise dividing the units of each measured quantity to yield the unit of the computed quantity (m/s = m/s). It's useful for something as simple as distance equals rate times time, but as you go into physics (non-leap year) Dimensional Analysis or the Factor Label Method Explained In the practice, many of the problems have the problems expressed in meters squared or cubed, but the video does not explain how to handle the numbers when converting from say, cm3 to m3 (sorry I don't know how to subscript!)

We're done. 1.50 x 10^-3 kg Includes short answer questions on math with significant figures and dimensional analysis. Hope this helps! viewed as rate times time. math is working out right. To yield the sought property, time, the equation must be rearranged appropriately: \[\mathrm{time=\dfrac{distance}{speed}} \nonumber \], \[\mathrm{\dfrac{25\: m}{10\: m/s}=2.5\: s} \nonumber \], Again, arithmetic on the numbers (25/10 = 2.5) was accompanied by the same arithmetic on the units (m/m/s = s) to yield the number and unit of the result, 2.5 s. Note that, just as for numbers, when a unit is divided by an identical unit (in this case, m/m), the result is 1or, as commonly phrased, the units cancel.. This is typically accomplished by measuring the time required for the athlete to run from the starting line to the finish line, and the distance between these two lines, and then computing speed from the equation that relates these three properties: \[\mathrm{speed=\dfrac{distance}{time}} \nonumber \], An Olympic-quality sprinter can run 100 m in approximately 10 s, corresponding to an average speed of, \[\mathrm{\dfrac{100\: m}{10\: s}=10\: m/s} \nonumber \].
