Question

L.A student was told that a drawing of a bacterial cell had been magnified 30 000 times. The length of the drawing was 45 mm. What was the actual length of the bacterium?

Answer 1

1.5 microns

Step-by-step explanation:

It is given that the drawing of the bacterial cell is magnified by 30,000 times.

The size of the drawing of the bacterial cell is 45 mm

=
`$45 * 10^(-3) \ m$`

Now size of the drawing = actual length of the drawing x magnification

Actual length of the bacterium is given by

=
`$\frac{45 * 10^(-3)} {30000}$`

`$= \frac{45 * 10^(-3)} {3 * 10^4}$`

`$= 1.5 * 10^(-6) \ m$`

or 1.5 microns
