1 Chapter 1 Systems of Measurement Conceptual Problems *1 •Determine the Concept The fundamental physical quantities in the SI system include mass, length, and time. Force, being the product of mass and acceleration, is not a fundamental quantity. correct.is)(c2•Picture the Problem We can express and simplify the ratio of m/s to m/s2to determine the final units. Express and simplify the ratio of m/s to m/s2: ssmsmsmsm22=⋅⋅=and correct.is)(d3 •Determine the Concept Consulting Table 1-1 we note that the prefix giga means 109. correct.is)(c4 •Determine the Concept Consulting Table 1-1 we note that the prefix mega means 106. correct.is)(d*5 •Determine the Concept Consulting Table 1-1 we note that the prefix pico means 10−12. correct.is)(a6 •Determine the Concept Counting from left to right and ignoring zeros to the left of the first nonzero digit, the last significant figure is the first digit that is in doubt. Applyincriterion, the three zeros after the decimal point are not significant figures, but the last zero is significant. Hence, there are four significant figures in this number.correct.is)(c
