Question

1 nanometer is ____ centimeter.

• A. ${10}^{-8}$
• B. ${10}^{-7}$
• C. ${10}^{-9}$
• D. ${10}^{-6}$

Answer 1

The correct option is B ${10}^{-7}$

$1$ nanometer $={10}^{-9}$ meter and $1$ centimeter $={10}^{-2}$ meter

So, $1$ nanometer $={10}^{-9}\times \frac{{10}^{-2}}{{10}^{-2}}$ meter $=\frac{{10}^{-9}}{{10}^{-2}}\times 1$ centimeter $={10}^{-7}$ centimeter
