I am currently taking Biology 2 and learning about Micro organisms like bacteria and fungi. However, I find both listening to my professor lecturing and reading the material draining and only slightly interesting. Its like learning another language where nothing seems to hold much significance...

No one able to explain #9? I was dissecting the angular momentum formula a bit more finding L = m * (w*r) * r. so I guess the angular speed (w) is inversely proportional to r^2. Does that allow me to arrive at 4 times the speed? It doesn't look like w depends on the radius though, so...

I should aslo mention I found this statement for question #9 on yahoo answers. (a different classmate must asked I guess) - Dr. Zoro not entirely sure I understand though

Thanks for the long write up eczeno I wish I could post the video I have of my professor talking about this portion of the project but it is too big of a file. You would like him, really cool guy :biggrin:. anyhow, he used the angular momentum formula: L = mvr where the conservation...

Does this look right for number 8? v = (1/r)*Pressure I'm guessing I'm way off.

Thanks What equation would I use to verify this though? I mean, how does this principle relate back to the ideas learned in fluid mechanics? or even all the way back Newton's laws of motion?

Similar to the first one with the trash can in this video: we made two separate cannons, one with a 5 inch hole and one with a 10 inch hole at the end. We made sure to pull back the bungie cord at the opposite end the same distance (8 inches) each time to approximate the same force for...

Hi all, I'm trying to answer the following questions related to a project on smoke rings. We are in an introductory class, so this project is more for fun and just applying the little we have learned about point, rigid body, and fluid motion to something less understood like vortex rings...

Thanks. Anyone have some ideas?

Hi guys, I realize this can be a rather uncanny occurance when a new member's first post is to ask for physics help on his homework but I've been lurking around the forum here for a while and am now in a really tight spot and thus had to get over myself and finally make an account...
