How many times as great is the diameter of a pinhead as the diameter of a cloud-water droplet

Ulleksa [173]

Given:

The diameter of cloud-water droplet is

$10^{-5}$

The diameter of pinhead is 0.001.

Explanation:

Divide the dimater of cloud-water droplet by dimater of pinhead to determine the times as great is the diameter of a pinhead as the diameter of a cloud-water droplet .

$\begin{gathered} a=\frac{0.001}{10^{-5}} \\ =0.001\cdot10^5 \\ =100 \end{gathered}$

So diameter of a pin-head is 100 times the diameter of water-droplet.
