Document Summary
1. 3 the micrometer is often called the micron. (a) how man microns make up 1 km? (b) what fraction of a centimeter equals 1 m ? (c) how many microns are in 1. 0 yard. We begin by calculating 1 km in microns d = 1. 0km 1000m. Now calculate a distance of 1 micron in cm. d = 1micron 1 10 6 m. Finally we compute a distance of 1 yard in microns. d = 1yd 3 ft. To do all three sections of this problem, we can first convert the radius to kilometers. r = 6. 37 10 6 m 1km. = 6. 37 103 km (a) the formula for circumference can be found in most calculus books (and in appendix e of your physics text). (6. 37 103 km)3 = 1. 083 101 2km3. 1. 7 antarctica is roughly semicircular, with a radius of 2000 km. The average thickness of its ice cover is 3000m.
