first, fill in the blank below with the correct unit. then use scientific notation to represent the quantity in meters. the thickness of a coin is about 2.15 (choose one) writing in scientific notation, this is meters.

Answer

Explanation:

Step1: Determine the unit

The thickness of a coin is usually measured in millimeters. So the unit is millimeters (mm).

Step2: Convert to meters

Since 1 mm = 0.001 m = $1\times10^{- 3}$ m, then 2.15 mm = 2.15×0.001 m = 2.15×$10^{-3}$ m.

Answer:

The unit is millimeters (mm); in scientific - notation, it is $2.15\times10^{-3}$ m.
