Answer:
9.19nm/s
Explanation:
We are given that
Hair grows per day=[tex]\frac{1}{32}[/tex] inch
We have to find the rate of grows in nanometers per second.
We know that
1 inch=[tex]2.54\times 10^7[/tex]nm
1 day=[tex]86400 s[/tex]
Using this formula
[tex]\frac{1}{32}inch/day=\frac{1\times 2.54\times 10^7}{32\times 86400}[/tex]
[tex]\frac{1}{32}inch/day=9.19nm/s[/tex]
Hence, the rate at which it grows in nanometers per second=9.19nm/s
