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 storage container with a precision of +/- 2 liters measures a volume of 3 liters and a cathetometer with a precision of +/- 0.0004 meters measures a distance as 0.0087 meters. You divide the numbers with a computer and get the output. Using the right level of precision, what is the answer? A. 344 liters/meter B. 300 liters/meter C. 344.8 liters/meter Answer:

Your calculator app produces the solution when multiplying the two numbers. If we write this solution suitably with respect to the number of significant figures, what is the result? A. 116000 liter-meters B. 116400 liter-meters C. 116480.000 liter-meters Answer:

After dividing the two values your computer produces the solution. Write this solution using the right number of significant figures. A. 43.02 meters/second B. 40 meters/second C. 43.0 meters/second Answer:

After multiplying the numbers your calculator app gives the solution. If we express this solution appropriately with respect to the number of significant figures, what is the result? A. 5100 meters^2 B. 5086.80 meters^2 C. 5000 meters^2 Answer:
