When magnified 1,000 times by an electron microscope, the image of a certain circular piece of tissue has a diameter of 2 centimeter. The actual diameter of the tissue, in centimeters, is Choose the correct answer:
A) 0.005
B) 0.002
C) 0.001
D) 0.0005
E) 0.0002
It is very easy if x is the diameter, then the magnified length is 1000x.   ince 1000x=2 then x=2/1000=0.002.   The answer is 0.002
