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.

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 spring scale with a precision of +/- 30 grams measures a mass of 800 grams and a clickwheel with a precision of +/- 0.003 meters measures a distance as 0.005 meters. Your calculator gets the output when dividing the values. How can we round this output to the suitable number of significant figures? A. 200000 grams/meter B. 160000.0 grams/meter C. 160000 grams/meter 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 divide the values with a calculator and get the solution. When this solution is expressed to the correct level of precision, what do we get? A. 85.71 grams/meter B. 90 grams/meter C. 85.7 grams/meter Answer:

After multiplying the former value by the latter your calculator gives the solution. Round this solution using the appropriate level of precision. A. 394026.600 gram-meters B. 394000 gram-meters C. 394026 gram-meters Answer:
