We open on the upstairs of a two-story house, where we see a young girl
talking into a radio transmitter.

Small moves Ellie, small moves.
= 109 μm.
The given measurement is 1.0 km (two significant figures), which implies our result
should be written as 1.0 × 109 μm.
(b) We calculate the number of microns in 1 centimeter. Since 1 cm = 10−2 m,
1cm = 10−2 m = (10−2m)(106 μ m m) = 104 μm.
We conclude that the fraction of one centimeter equal to 1.0 μm is 1.0 × 10−4.
(c) Since 1 yd = (3 ft)(0.3048 m/ft) = 0.9144 m,
