When magnified 1,000 times by an electron microscope, the image of a certain circular piece of tissue has a diameter of 1 centimeter. The actual diameter of the tissue, in centimeters, is	Answers:	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=1 then x=1/1000=0.001.   The answer is 0.001
