OpenStudy (anonymous):

no.. i didn't ask u to answer but help me in answering this and the above q' states wht eqiupments r available thats all

OpenStudy (anonymous):

what class is this for?

OpenStudy (anonymous):

and what kind of dirt is it?

OpenStudy (anonymous):

wht do u mean?? its the dirt that is found in muddy water

OpenStudy (anonymous):

when is the exam?

OpenStudy (anonymous):

thurs

OpenStudy (nottim):

Oh. What class?

OpenStudy (anonymous):

if you leave the water sitting in the plastic bottle or the cup the dirt might settle to the bottom

OpenStudy (anonymous):

thats wht my answer is bt my teacher said no.. still some dirt would be left in water

OpenStudy (nottim):

Or maybe apply a continuous centripetal force, like a centrifuge. Would force the heavier objects (e.g. dirt) to one side

OpenStudy (anonymous):

pour the mud congaing water in the bottle and wait for some time until the mud settles down, and with the cup collect the upper water and drink

OpenStudy (anonymous):

@sraone88 read the replies above

OpenStudy (anonymous):

i replied to the same answer bt from someone else

OpenStudy (nottim):

what type of cup is it?

OpenStudy (anonymous):

it does not state the type of cup u have in the q'

OpenStudy (nottim):

cause if tis a paper cup, then this simplifies the situation.

OpenStudy (nottim):

just user it as a filter.

OpenStudy (anonymous):

i dont know the type

OpenStudy (nottim):

Did I already talk about centripetal forces? Or did I just answer the wrong person

OpenStudy (anonymous):

a paper cup would be hard to use as a filter

OpenStudy (nottim):

Use a centripetal force, or maybe that centrifuge, and spin the bottle extremely fast, forcing the heavier objects (dirt) to the 'outside'

OpenStudy (anonymous):

@NotTim wht?????

OpenStudy (anonymous):

@sraone88 has the best answer here, I think

OpenStudy (anonymous):

ya sure with that situation keep in mind.....

OpenStudy (anonymous):

thats wht my answer waz... i wrote the exactly same thing bt its apparently wrong
