@mbm13,
I suspect a terrible fraud is in our midst. Or your thread is poorly title....

Are you implying that you are presently pursuing a doctoral degree and that you have the audacity to get homework help? Hopefully you're not getting any degree in science and hopefully your academic pursuit is in philosophy or literature.... You should already know about fluids and density before you graduate and receive your bachelor's degree in science.

@tsarstepan,
Yeah, I gave him/her the benefit of the doubt. I just finished reading about adult science (il)literacy in the US, so I was primed to answer.

@tsarstepan,
Hmm...
I can conceive of a PhD thesis on "the nature of scientific explanation", but obviously not on elementary physics. On the other hand, anybody who uses lower case "phd" is unlikely to be operating at post graduate level.

And I suspect they wouldn't use the phrase Describe why an object will sink. Shouldn't it be Describe how an object will sink, or Explain why an object will sink?

Who knows? Those for $25 might have a question to answer (if you pay more, you get your "phd" without any homework).
