Any help on this?

Soap Bubbles in terms of optics etc. Help needed :) Homework Statement The opening of a metal cylinder is dipped in soapy water so that a soap film forms. The cylinder is then turned so it is horizontal (and the soap film is vertical). What happens to the thickness of the soap film...

Homework Statement For this project, we had to build a vehicle that would hold an egg, and drop it a distance of about 40 feet, and making sure the egg wouldn't break. There are various parts to the report part of this project, and I had a question about the first part. Basically, one part...

Homework Statement Okay so I want to be able to do this in Microsoft Word 2003: http://upload.wikimedia.org/math/e/7/b/e7b1daa5e6f9f335dabcc1ca136c93a8.png Homework Equations None. The Attempt at a Solution However, the problem is, when I try to do subscripts and superscripts...

I'd also appreciate it if anyone could confirm another thing: Looking at pendulum mass vs. period, what does the trend seem like? I think when the mass increases, the period increases as well.

Thanks for all the help. Yes, the formula for the period doesn't have anything to do with the amplitude right (Since T = 2(pi) square root of L/g)? I am still a bit confused though.. I understand why the amplitude would decrease, but wouldn't a lower amplitude mean it takes less time to go back...

Homework Statement So basically, we had a mass attached to a string (like a pendulum), and we pulled it back .1 m and then let go and watched it go back and forth. We have a huge lab to do for stuff like this, and there were three questions that I want to be sure I get right since they lead...

I'm not sure, that was just one of the conceptual problems on the worksheet we got for reviewing the last few chapters (since finals are coming up) =/

Help?

No problem.

Fine, wrong.

Homework Statement How does the Earth's rotation affect an apple that is dropped from a tree? Homework Equations None The Attempt at a Solution Er... I'm not 100% sure on this one =/. Does it pull on it as it falls down or something? Help would be MUCH, much appreciated, thank you!

The weight w/o the egg is 45-55 grams (has to be). Thanks for your suggestion, cushioning is when you put tissues/cotton balls, etc. to break the fall.

Homework Statement Hey, I was wondering what the proper section to post this in, and if it is okay to post it: I have to do a project that goes something of this sort: Basically build a vehicle no more than an empty mass of of 50 +/- 5 grams, and drop it from a point of approximately...
