Final answer:The diameter of a United States penny is closest to 10-2 m, which represents 2 centimeters. This scientific notation corresponds to the actual approximate measurement of a penny's width.Explanation:The diameter of a United States penny is closest to 2 centimeters (cm). In scientific notation, 2 cm is expressed as 0.02 meters (m), which can also be written as 10-2 m. Therefore, the correct answer to the question is b. 10-2 m.When looking at the available choices, it is evident that a 100-meter diameter is far too large for a penny, micro units are too small, and a millimeter is also smaller than the actual size of a penny. The provided equivalence table helps confirm that 1 cm equals 0.01 m or 10-2 m, which aligns with our estimation of a penny's diameter being close to 2 centimeters wide....
