We're going to get distance is The only container readily available is a 150-mL Erlenmeyer flask. Dimensional analysis is a method of problem solving that allows us to use relationships between quantities as "stepping stones" to solving complicated problems. Answer: 0.5 gallons/ 1 day times 16 cups/ 1 gallon times 7 days/ 1 week, Jackrabbits are capable of reaching speeds up to 40 miles per hour. One way we measure a change in temperature is to use the fact that most substances expand when their temperature increases and contract when their temperature decreases. What's that going to give us? There are 60 questions in all, so you can pick and choose which questions you want your students to use. 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). Jackrabbits are capable of reaching speeds up to 40 miles per hour. 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.. There are prescribed instructions that one should follow when undertaking this analysis. Answer key and mathematics reference sheet included.
