Where are the alkali metals and the halogens located on the periodic table? (a) 1000 meters = 1 kilometer, A:The following conversation factors are For example, 432,500 is 433,000 to 3 significant digits (using half up (regular) rounding). Placing a prefix in front of a metric unit can increase or decrease that unit by a factor of ten, - abbreviation = L The rule about uncertain digits is that there can be one and only one estimated or uncertain digit in a measurement. Leading zeros before a number are not significant. The trailing zerois significant because the number contains a decimal place (see rule #4 above). "729" must be estimates, since they are produced by multiplying by an But we must also estimate one, and only one, additional digit. rounded to the tenths place. Use the dating theory calculator to enhance your chances of picking the best lifetime partner. 25.45 cm is the best estimate (so far) for the They are written for relationships between units of the metric system, U.S. units, or between metric and U.S. units. point are significant because they lie between significant Silver, Conversions Factors & Problem Solving LAB 2, The Criminal Offender Midterm 1-7 (1-4 comple, Bruce Edward Bursten, Catherine J.
