The image of a dust mite from a scanning electron microscope is \(1.5 \times 10^2\) millimeters wide. The image is \(5 \times 10^2\) times life size. How many millimeters wide is the dust mite?

Answer :

Given that The image of a dust mite from a scanning electron microscope is [tex] 1.5 \times 10^2 [/tex] millimetres wide. And that image is [tex] 5 \times 10^2 [/tex] times life size. Now we have to find how many millimetres wide is the dust mite. To find that we just need to divide the the width of dust mite by the scale value of microscope. I mean divide [tex] 1.5 \times10^2 [/tex] millimetre by [tex] 5 \times 10^2 [/tex]

So the answer is given by

Width of the dust mite [tex] =\frac{1.5 \times 10^2}{5 \times 10^2} =\frac{1.5 }{5 } =0.3 [/tex]

Hence final answer is 0.3 milimetre.



600 millimeters is the accuracy
