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

9.19nm/s

Step-by-step explanation:

We are given that

Hair grows per day=
`(1)/(32)` inch

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

We know that

1 inch=
`2.54* 10^7`nm

1 day=
`86400 s`

Using this formula

`(1)/(32)inch/day=(1* 2.54* 10^7)/(32* 86400)`

`(1)/(32)inch/day=9.19nm/s`

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