    1 pipe branching into 3 pipes, pressure of each branch?

    I believe the pressures would be the same if they're all laying horizontally flat. If the system is set up vertically so that one pipe is higher (relative to the lower pipe) then the pressures would not be the same according to Bernoulli's equation..

    Electric Potential Energy Problem. Intuition needed

    Apparently B would have a speed the same as the particle that accelerates to the right which is also the speed of the particle that accelerates to the left. And there's nothing more to the question that's it.

    Electric Potential Energy Problem. Intuition needed

    There's this problem that was given in my physics class.. "Three identical, negatively charged particles are situated at rest in a straight line, as shown below. All three are released simultaneously, and are free to move. Find the maximum velocities attained by particles A, B, and C. They have...

    Integration to find Electric Field at a point P -- dQ or dq?

    Hey everyone, So I've been learning about electric fields and all that good stuff. So now the question arises, what is the electric field at a point P away from an object (say a rod or a ring) at a distance D away? So we know E=Kq/r2 or E=KQ/r2 . The difference between q and Q: q the charge for...

    Am I wrong, or is my professor? Intensity Question

    still haven't heard a compelling answer to my question. Anyone?

    Am I wrong, or is my professor? Intensity Question

    Which intuitively makes sense right? The rate at which energy is transferred in a wave should be greater in water since it's denser, meaning more friction etc..

    Am I wrong, or is my professor? Intensity Question

    right, but again, Intensity isn't telling you how much energy you have it simply tells you the rate at which energy is transferred through an area. It doesn't tell me anything at all about the energy these particles have.

    Am I wrong, or is my professor? Intensity Question

    Right, exactly. The way sound waves move is do to a variation in pressure. The particles themselves oscillate but cause the one near them to begin to oscillate themselves. Hence, there is an acceleration caused by a group of particles on another group of particles and a mass of the particles, a...

    Am I wrong, or is my professor? Intensity Question

    I see. So what do you think of my explanation so far? Since its a rate you don't have to ask, where did those joules come from? It's like me saying, v1= 10m/s then saying v2=20m/s , you don't ask, where did those meters come from. It's just a rate. similarly here, I believe its just a rate at...

    Am I wrong, or is my professor? Intensity Question

    and I'm a little unclear on what a converging lens effect does/is in this case..

    Am I wrong, or is my professor? Intensity Question

    Well.. Power = Force x velocity. So you have a constant force but increase the velocity so you have higher watts.

    Am I wrong, or is my professor? Intensity Question

    Intensity = Poweravg/Area so W/m2 or J/sm2

    Curious question about light/photons

    I'm a little unclear on the question and I'm no where near qualified to add to this since I don't even have my Bachelors yet but I'll give it a whirl. I think what you're asking is; is there any way we can manipulate wavelengths of colors to perceive the world in a different color? I think the...

    Am I wrong, or is my professor? Intensity Question

    Hello everyone, please help me understand this. We were given a conceptual question that says "A sound wave goes from the air into the ocean. Which of the following applies (circle all that apply): a)its intensity increases b) its wavelength decreases c) its frequency increases d)its...

    Derivation of the speed of sound waves equation

    This may come off as completely rude but I understand the derivation now.. sorry :( yes its for Newtons formula for speed in sound..
