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 .

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 ruler with a precision of +/- 0.4 meters takes a measurement of 377.3 meters, and a clickwheel with a precision of +/- 0.004 meters reads 0.037 meters when measuring a distance between two different points. Your calculator gives the output when multiplying the former number by the latter. When this output is expressed to the right number of significant figures, what do we get? A. 14.0 meters^2 B. 13.96 meters^2 C. 14 meters^2 Answer:

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.

You multiply the former number by the latter with a calculator and get the solution. How can we express this solution to the suitable number of significant figures? A. 211.68 liter-meters B. 211.7 liter-meters C. 210 liter-meters Answer:

After dividing the numbers your calculator gets the solution. When this solution is reported to the proper number of significant figures, what do we get? A. 1564.833 grams/second B. 2000 grams/second C. 1564.8 grams/second Answer:

You multiply the two values with a computer and get the solution. If we express this solution to the suitable level of precision, what is the answer? A. 900 gram-seconds B. 980.0 gram-seconds C. 1000 gram-seconds Answer:

After multiplying the first number by the second number your calculator app yields the solution. Using the appropriate number of significant figures, what is the answer? A. 186.4 gram-seconds B. 186.4288 gram-seconds C. 186 gram-seconds Answer:
