Question

Suppose your hair grows at the rate of 1 32 inch per day. Find the rate at which it grows in nanometers per second. Answer in units of nm/s.

Answer 1

Answer:

9.19nm/s

Explanation:

We are given that

Hair grows per day=$\frac{1}{32}$ inch

We have to find the rate of grows in nanometers per second.

We know that

1 inch=$2.54\times 10^7$nm

1 day=$86400 s$

Using this  formula

$\frac{1}{32}inch/day=\frac{1\times 2.54\times 10^7}{32\times 86400}$

$\frac{1}{32}inch/day=9.19nm/s$

Hence, the rate at which it grows in nanometers per second=9.19nm/s
