Thanks. I get it now.

OHHH! I get it.

Hmm. Okay. Another question, then. Is the following statement true?: the narrower the pipe, the higher the density Nvm, reading the previous post.

"increasing velocity increases pressure" I thought the whole idea of Bernoulli's principle was that increasing velocity decreases pressure...?

I'm positive that we weren't taught the right hand rule..

I have in my notes that as speed of a fluid increases, density decreases. This doesn't make sense to me. When a fluid passes through a narrower area, doesn't that mean that its density is increasing because it is now packed more tightly together? If this is the case, shouldn't the rule be that...

Homework Statement Make the following into a web address; it wouldn't let me post one. img161.imageshack.us/img161/3728/physicspv5.pngimg161.imageshack.us/img161/3728/physicspv5.b3825b8665.jpg[/url] What is the net torque on this object? Homework Equations torque=(radius)(force)(sin(...

I don't think so. It's not for us to know.

I have written in my notes the following: "Total internal reflection will have reflecting ray only, same as incident (60 degrees)." I understand everything but the 60 degrees part. If there is total internal reflection, will the angle of reflection and the angle of incident both always be...

The problem: Two speakers emit a sound with a frequency of 550.0Hz. At what distance should they be placed to maximize destructive interference? I have the steps in solving this problem written on my worksheet, and it says that the speakers should be placed at 1/2 wavelength. The thing I...

What happens to the amplitude of an electromagnetic wave when it crosss from a less dense to a more dense medium? I couldn't find it anywhere on the net.

Homework Statement The force on a wire .80 m long that is perpendicular to the Earth's magnetic field is .12 N. What current flows throught the wire? (Earth's magnetic field is 1.0x10^-4 T at the poles and 5.0x10^-5 T at the equator) Homework Equations Fm=BIl Fm is magnetic force in N...

Lol, I guess I do now that I figured that out. Nevermind!

It's not a specific problem, but I'm wondering what "parallel force" is defined as. The equation we were given is work = parallel force x distance. I was thinking that parallel force is probably the sum of the forces acting in the direction of motion, but some problems we've done in class...
