A human hair is approximately 22.637 micrometers in diameter. Express this diameter in meters. Note, your answer may be decimal (e.g. 0.03 m) or in scientific notation (e.g. 3.0E-2; note that "E-2" means ten raised to the -2 power).
Use dimensional analysis. The micrometers cancel out leaving you with meters. \((2.2637*10^4\mu m)*\frac{1m}{10^6\mu m}\\ 2.2637*10^{-2}m\)
The correct answer is: 22.637 / 1,000,000 =2.2637E-5 meters.
