0.2 macro meters magnified 1500 times is,?

Question

i need this i cant do these wasnt exaplained well at school

Answer 1

I assume you meant micro-meter. It would still be 0.2 micro-meters, because magnifying any thing only changes the path of the light reflected from the object to your eye. It doesn't change the physical size of the object, it just makes it look larger. If you ask 'what would the size of a 0.2 micro-meter object appear to be when magnified 1500 times'? The answer is 0.2 micro-meters x 1500 = 300 micro-meters.
P.S. a micro-meter is 1,000,000th of a meter, not 1000th assomeone answered. Also a micrometer is also a measurement device, as is a micrometer, buut for different measurements see these links http://en.wikipedia.org/wiki/Macrometer and http://en.wikipedia.org/wiki/Micrometer

Answer 2

I will assume you meant micro-metres (Macrometer is an instrument for measuring the size and distance of distant objects [wikipedia]), which is 1/1000 of a milimetre, or 1/1000000 of a metre.
0.2 micrometre * 1500 = 300 micrometre = 0.3 milimetre = 0.03 centimetres = 0.0003 metres.

I hope I'm clear. Good luck!

Answer 3

I think you meant micro which is 1 divided 1000 times. Use this link. http://www.mathmojo.com/interestinglessons/names%20of%20large%20numbers/names_of_large_numbers.html
