**Unformatted text preview: **1. The metric prefixes (micro, pico, nano, . . .) are given for ready reference on the inside front cover of the textbook (see also Table 1-2). (a) Since 1 km = 1 103 m and 1 m = 1 106 m, 1 km = 103 m = (103 m)(106 m/m) = 109 m . The given measurement is 1.0 km (two significant figures), which implies our result should be written as 1.0 109 m. (b) We calculate the number of microns in 1 centimeter. Since 1 cm = 10-2 m, 1 cm = 10-2 m = (10-2 m)(106 m/m) = 104 m . We conclude that the fraction of one centimeter equal to 1.0 m is 1.0 10-4 . (c) Since 1 yd = (3 ft)(0.3048 m/ft) = 0.9144 m, 1.0 yd = (0.91 m)(106 m/m) = 9.1 105 m . ...
