Homework Help Overview

The discussion revolves around buoyancy and fluid dynamics, specifically addressing questions about gas pressure in balloons and the nature of buoyant force on submerged objects.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants explore the relationship between internal and external pressures in a balloon, questioning whether the gas pressure is greater, equal, or less than the external air pressure. They also discuss the reasoning behind buoyant force acting upward on submerged objects, considering various answer choices and their implications.

Discussion Status

Some participants provide insights into the pressure dynamics of balloons and buoyant force, while others express confusion over the wording of the questions. There is acknowledgment of differing opinions on the correct answers, with suggestions to clarify ambiguities with the instructor.

Contextual Notes

Participants note that the questions may appear on an upcoming test, increasing the urgency for understanding the concepts. There is mention of a potentially misleading source regarding fluid pressure that some participants are trying to clarify.

I am going to go over to the general discussion area and post a poll. The poll is going to concern what Doc Al's avatar really is. And I'm also going to ask for suggestions for an avatar for Cookiemonster. He can't use NateTG's hilarious excuse of having an invisible avatar. I'll only buy that once!

Nate might be serious. You can make transparent layers in Photoshop you know :wink:.

So far no one has figured out the deep meaning of my avatar. Who will accept the challenge?

It is upside down.
It is recognizable if rotated 180 degrees. IMHO

It's pretty vauge. How about the impact of Shoemaker-levy 9 on Jupiter? Particle decay in a cloud chamber. A stylized face - eyebrows nose and cheekbone on a circular head. A palmtree blowing in the wind in front of a rising moon. The initails T.O. A rocket taking off of surface of the moon.

Well Folks, it may just remain a mystery. I tried to look at the so-called avatar upside down, as marcus suggested. Thanks for getting me to put a crick in my neck, marcus! ha ha It looks upside down from upside down...

Over in the General Discussion area, we are saddled with a bunch of slugs too lazy to get into the discussion. Hmmph. I put up two questions, one asking what Doc Al's avatar is, and one asking for an avatar for cookiemonster. I guess everyone is too busy thinking lofty physics thoughts to join in. In the meantime, people are going about sans avatar and Doc Al continues to use a poorly-drawn peach as an avatar!

So I am going to post on my website a few avatars I think would be good for cookiemonster and marcus and turin. Doc Al can get himself a nice, happy, colorful one, too. NateTG can keep his ol' invisible one. It's probably a mean-looking smiley saying a bad word, ha ha!

"Ask a Stupid Quetion Get a Stupid Answer," lofty physics indeed!
