Answer:
If 100 million atoms are stretched placing each atom side by side, it will make a length of 1cm long. Thus a 100 million atom stretch would be 1cm wide.
Step-by-step explanation:
The size of atom is very small. Although stretching atoms side by side and stretching it consisting of 100 million atoms is physically impossible, it has been scientifically proven that the 100 million atoms would make 1 cm long width.
The calculation is based upon the average diameter of the atom. If we multiply the average diameter of atom 100 million times then the result will be 1cm.
