In your BIO 111 course, you learn that human hair can vary in diameter, but one estimate of the average diameter is 50 microns o
r 50 x 10-6 meter. How many 10-nanometer (is 10 x 10-9) particles could be stacked across the diameter of a human hair?
1 answer:
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
