Answer :
Final answer:
A Vernier caliper is used to set a divider to an exact dimension due to its ability to measure small increments to high precision, often to the nearest 0.01 millimeter.
Explanation:
The tool generally used to set a divider to an exact dimension is a Vernier caliper. Vernier calipers are precision instruments that can measure small increments of length very accurately, often to the nearest 0.01 millimeter. When discussing the precision of measuring tools and significant figures, it's important to recognize that Vernier calipers are significantly more precise than a standard ruler, which typically measures length to the nearest millimeter. In practice, to set a divider accurately, one would first use the Vernier caliper to measure the length, width, or diameter of an object, and then adjust the divider accordingly to replicate that measurement accurately.
