Question

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

Answer 1

Given:

The diameter of cloud-water droplet is

`10^(-5)`

The diameter of pinhead is 0.001.

Step-by-step 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=(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.
