Thickness of strand hair = 50 μm
Diameter of an atom = 
Now, with the help of conversion factors, convert thickness in micrometer into meter i.e. 1 micrometer = 
So, thickness of strand hair =50 μm= 50 \times 10^{-6} m
Therefore,
number of atoms thick is a strand of hair = 
= 
Hence, number of atoms is thick is a strand of hair.
Answer:
Protons and Neutrons are found in the nucleus
Answer:
It might be responding variable.
A chemical reaction that removes electrons from an atom is called "O<span>xidation".
The term came from late 18th century from French.
When the electrons are removed from an atom it increase its valence.</span>
<span>My hypothesis is the the cell, having a higher osmolarity than the solution of of nacl in the beaker, will have an osmosis reaction releasing into the solution of nacl. This will continue until both cell and solution reach a balance.</span>
