Let's make a homework help thread!

Thanks, blackcat. I kind of have an idea of what I want to write, I'm just clueless as to how to organize the paragraphs. I'll deal.

I'm an engineering student, I'm decent with math and physics as long as we don't go too in depth. I'm having issues with heat transfer right now, any takers?

I am really good at math, so I can likely help for everything up to second-year University calculus. I tend to know a fair bit about science, but I'm better at calculations than theory.

My homework is a bit different.

• Low-voltage cable typically contains solid wire sizes ranging from _____ AWG.
  • a. No. 28 to No. 14
  • b. No. 26 to No. 12
  • c. No. 22 to No. 10
  • d. No. 20 to No. 8

Hmm. How did I miss this thread?

T'will be useful when I need to write my essay...

Hey, anyone can give me some pointers on Benito Cereno? I need to write a three page analysis of it, and don't really have time to read it through.

For extra credit in Physics class, I need to come up with a 3 page essay on either of the following:

"1. Write about the physics underlying the operation or function of an instrument. For example: How does a stethoscope work? How do X-ray machines work? How does a LASER work? How does a car engine work? How does an ipod work? What is the role of physics in playing the violin? etc…"

or

"2. Write about the contributions to physics by a famous physicist. Include a short paragraph about when and where the scientist was born (and died if necessary). I want you to focus on the contribution to physics by this person." (Exceptions include Sir Issac Newton and Albert Einstein, because they're too popular/ essays would be too numerous for the teacher to consider them to be worth reading)

Any suggestions? any way TV Tropes can help (yeah right)?

Essay on instrument. Guitar. Sounds easiest.

I know a few metal heads and musicians, so this should be easy.

Thanks, Mellon.

No prob

@Jethro

Oppenheimer helped prevent future world wars with his research. And helped produce one of the most effective sources of energy there is.

Go with Mellon's suggestion. Political themes on academic essays should be avoided unless relevant.

8/(3 + sqrt2). Does anyone know how to simplify this by rationalising the denominator? Thanks in advance.

Multiply both the numerator and the denominator by 3 - sqrt(2). Most situations like this tend to be resolved with the differences of squares formula, so make sure to be comfortable with that.

^ Thank you.

In an odd way, this thread is a Crowning Moment Of Heartwarming, seeing us tropers help each other out.

Alright, so I have one more lame question to ask before I actually start contributing to my own thread. Please forgive me! The question hardly makes any sense in any context relevant to what I've studied thus far, so I'll just post it in it's entirety and see if anyone here knows what to do.

• Provide an example of a sex-linked trait and explain why these traits usually only show up in males.

Colorblindness is a recessive trait on the X chromosome. It shows up more on males because males only have one X chromosome but females have two.

You have done a great thing, William Wide Web! I can't offer you anything tangible in exchange for your help, but here is an infinite supply of e-cookies!

Please help with my precal homework.◊ I'd greatly appreciate it.

Oh... sorry. Damn photobucket's blocked.

Oh, that sucks Kinkajou. Well, surely someone else can help. Like, I know Ironeye's lookin' at it right now.

What part of it are you having issues on? Do you just need a refresher on the Law of Sines and Law of Cosines or is it a matter of knowing how to use them?

It's more that it doesn't look like I have enough info to do it.
