Question

Convert to meters (m).

73 pm

• A. $73\times {10}^{-12}m$
• B. $73\times {10}^{-2}m$
• C. $73\times {10}^{-15}m$
• D. $73\times {10}^{-9}m$

Answer 1

The correct option is A $73\times {10}^{-12}m$

We know that $1pm={10}^{-12}m$

$\therefore$ $73pm=73pm\times \frac{{10}^{-12}m}{1pm}=73\times {10}^{-12}m$
