Step 1 of 3

August 29, 2016 Scientific Notation 578.762 0.00000772 move decimal move decimal 5.68762 x 10 2 7.72 x 10 -6 N x 10 n N is a number between n is a positive or negative 1 and 10 integer Significant Figures in Calculations 1. For addition and subtraction, the result has the same number of decimal places as the measurement with the fewest decimal places. 2. For multiplication and division, the result contains the same number of significant figures as the measurement with the fewest significant figures. The rest of class we worked on the Sig Figs and Scientific Notation worksheet. August 30. 2016  The number of significant figures is not changed by changing units  The number of significant figures is not changed by scientific notation Dimensional Analysis  We use to convert one quantity to another  Utilizes conversion factors o Ex: 1in = 2.54 cm Prefixes to know M Mega 10 6 K kilo 103 c centi 10 -2 1/100 -3 m milli 10 1/1000 -6 µ micro 10 n nano 10 -9 p pico 10-12 Conversions in Metric System 6 1 km = 1000 m 1 g = 1000 mg 1 g = 10 µg
