Significant Features in a given measurement mean like specific digits from a number. The rules are: 1) Nonzero digits are always significant 2) All final zeroes after a decimal point are significant 3) Zeroes between two other significant digits are always significant 4) Zeroes used soley as placeholders are NOT significant 5) Zeroes between a decimal point and a nonzero digit are significant. 34900 would have 3 significant features. 0.0034900 would have 5. I hope that helps. I got the information from this website: http://www.hazelwood.k12.mo.us/~grichert/sciweb/phys8.htm There are tons more practice problems and info.

What is the greatest possible error for the measurement 4.7 cm?
If the number of significant digits is correct, this measurement should be between 4.6 and 4.8 and thus have a possible maximum error of 0.1.
What is the total angle measurement of a hexagon?
The total angle measurement is 720 degrees.
What the rules in expressing a number in scientific notation?
1. All non-zero digits are always significant. 2. Zeroes between other significant figures are significant. 3. Trailing zeroes without a decimal point are not significant. 4. Trailing zeroes after a decimal point are significant. 5. Leading zeroes that come before a non-zero number are not significant. 1. 2598 has four significant figures. 2. 25005 has five significant figures. 3. 160 has two significant figures. 4. 45.800 has five significant figures. 5. 00.00589 has three significant figures.
Suppose a paper clip is measured at 3 cm What is the percent error in this measurement?
This is a two step problem: First you must find the Greatest Possible Error (GPE)? To find the greates possible error, you must acknowledge the significant place value. In this case because it is measured to 3cm the answer is 1cm. The GPE is half of 1cm which is 0.5cm. Second the percent of error is a ratio of the GPE/Original measurement. In this case it is 0.5/3 is 0.16666666667 therefore the answer is: approximately 16.67% or 16.7% or 17%
