Answer:
5000 particles of size 10 nanometer should be stacked
Step-by-step explanation:
Average diameter of the of the human hair = 50 micron = 50 × 10⁻⁶ m
Now,
let the number of 10 nanometer i.e 10 × 10⁻⁹ m particle be 'n'
thus,
n × 10 × 10⁻⁹ m = 50 × 10⁻⁶ m
Therefore to find the number of 10 nanometer i.e 10 × 10⁻⁹ m particle,
n = ![\frac{50\times10^{-6}}{10\times10^{-9}}](https://tex.z-dn.net/?f=%5Cfrac%7B50%5Ctimes10%5E%7B-6%7D%7D%7B10%5Ctimes10%5E%7B-9%7D%7D)
or
n = 5000
Hence,
5000 particles of size 10 nanometer should be stacked
Since the 4 is underlined in 6.5<u>4</u> it means it is in the hundredths place so the value would be 0.04.
