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 =
or
n = 5000
Hence,
5000 particles of size 10 nanometer should be stacked
Given:
The postal service charges $10.30 per pound on the package shipped to England.
To find:
The rate in dollars per ounce.
Solution:
We know that,
1 pound = 16 ounce
