Omega Definition and 68 Threads

For a capacitor in an AC circuit, does \omega = \frac{1}{RC} always? I have voltages such as Vg = 2cos(105t) V. When finding the capacitance using the formula C = \frac{1}{jwc} would I use \omega = 105 or would I use \omega = \frac{1}{RC}?

I thought that in the formula v=wr, r refers to the distance from the center, i.e., the radius. However, if the wheel is rotating on the ground, the books says that the linear speed at the top of the tire is 2rw, as opposed to rw. Why is this?

Can someone please explain the difference in Angular Velocity for a Horizontal and a Vertical circle? :confused:

I'm trying to apply the Omega Equation to a set of surface data. Can anyone further break down the omega equation into its individual parts and give formula's to solve them. In particular parts like the geostrophic vorticity I've so far managed to find the geostrophic wind and static...

Homework Statement An Omega- particle has rest energy 1672 MeV and mean lifetime 8.2X10-11 s. It is created and decays in a particle track detector and leaves a track 24mm long. What is the total energy of the Omega- particle? Homework Equations E=E0/Sqrt(1-v^2/c^2) E0=1672 MeV...

I know modern society is lacking an adequate omega 3 intake. They claim that we get a 10:1 to 20:1 ratio of omega 6:omega 3. But if it was reversed and we got 10 to 20 times the amount of omega 3 to 6, what would the side effects be? I am trying to find any article or study done showing this...

This question concerns Omega(matter+dark+lambda). We take into account protons(baryons), electrons(leptons), neutrinos, pions, etc etc when trying to determine Omega from the CMB. but what about photons? I mean there are A LOT more photons than baryons. All those photons carry energy...

Hi folks, Firstly I would like to introduce myself. My name is Owen and I am a science teacher from Australia. I am a bit of a ponderer and after watching a doco on string theory I started thinking about our existence, as I often do, you know, the basic things such as... "Why is there...

Hi, I was wondering, do mathematicians (like computer scientists) use things like Big O, Big Omega, Little O, etc. a lot? If so, in what context?

If Omega was exactly 1... We know if the value of omega (the average mass of all matter int he universe was) was more than 1, the ultimate fate of our universe is the big crunch; also if omga was less than one, there wouldn't be enough gravitational pull to bring all matter back, however will...

phrase velocity and "omega" what's the difference between phrase velocity and "omega"?

Can someone explain the Omega pointe to me? In regards to the theory of the universe collapsing?

I am having trouble with the following problem: Find the value(s) of [tex] \omega [\tex] for which [tex] y = \cos(\omega * t) [\tex] satisfies [tex]\frac{d^2*y}{d*t^2} + 9y = 0[\tex] I am trying to use latex but it doesn't seem to be working when I do "preview post" so I will rewrite...

I need to prove the Theorem: If omega is equal to infinity then D =[0,infinity) and if omega<infinity, then D =[o,infinity]. Where omega=the least upper bound of D and D=the set of all distances that occur between points of the plane. I'm really just not sure where to start, but I'm pretty...

we are just about to take a test in physis.. I am quite scared. i have revised on all the topics required but i don't get the use of omega in angular velocity equations. what is the equation and when do i need to use it? sarah

What is the currently accepted value for Omega of radiation energy density (photons and neutrinos)? References would be helpful. Thanks.

I first read this story in New Scientist when I was collecting it. Here are some highlights: The article has been reposted here: http://www.you.com.au/news/362.htm and in many other places. Any comments?
