NOTE: To propagate uncertainty when multiplying or dividing two measurements, count the number of significant figures in each. Your result should be reported to the number of significant figures in the measurement having the lesser number of significant figures.

NOTE: To propagate uncertainty when multiplying or dividing two measurements, count the number of significant figures in each. Your result should be reported to the number of significant figures in the measurement having the lesser number of significant figures. Note that 'significant figures' are different than 'decimal places'; see rules at https://en.wikipedia.org/w/index.php?title=Significant_figures&oldid=1114415444#Identifying_significant_figures . Rounding a number to N significant figures is similar to rounding to N digits after the decimal point, except that we start counting from the beginning of the number. For example, 71.25150 rounded to three significant figures is 71.3, to four is 71.25, and to one is 70. (If the N + 1 digit is 5 followed by nothing or by zeros only, use the 'round half to even' tiebreaking rule). --- A measuring flask with a precision of +/- 0.002 liters measures a volume of 0.212 liters and a measuring stick with a precision of +/- 0.01 meters measures a distance as 3.09 meters. Using a calculator app, you divide the first value by the second value and get the solution. Using the suitable level of precision, what is the answer? A. 0.07 liters/meter B. 0.0686 liters/meter C. 0.069 liters/meter Answer:

Using a computer, you multiply the two values and get the solution. If we round this solution properly with respect to the level of precision, what is the result? A. 14376.00 meters^2 B. 14370 meters^2 C. 14000 meters^2 Answer:

After dividing the former value by the latter your calculator app yields the output. If we write this output suitably with respect to the number of significant figures, what is the answer? A. 1367 meters/liter B. 1360 meters/liter C. 1367.3390 meters/liter Answer:

After dividing the two numbers your computer yields the output. If we report this output appropriately with respect to the number of significant figures, what is the result? A. 0.06 meters/liter B. 0.060 meters/liter C. 0.1 meters/liter Answer:
