A machinist has a sophisticated micrometer that can measure the diameter of a drill bit to 1/10,000 of an inch. What is the maximum number of significant figures that should be reported if the approximate diameter of the drill bit is:

(a) 0.0001 inches,

(b) 0.1 inches,

(c) 1 inch?

Assume that on the surface of the Earth, g = 9.81 m/s² = 32.2 ft/s² (i.e., each to three significant figures). Make sure you are reporting the solution to the proper number of significant figures.
