    Understanding De Broeglie Wavelength & Electron Orbits

    Cool thanks! That really blows my year 12 understanding out of the water.

    Understanding De Broeglie Wavelength & Electron Orbits

    Electrons orbits are only allowed when a stable standing wave is formed around the nucleus, i.e. when the orbit circumference is an integer multiple of the electron's de broeglie wavelength. But is it possibly for it to temporarily exist in an orbit that is NOT an integer multiple of its...

    What is the relationship between relativistic currents and Ohm's Law?

    Ok, well regardless of this small technicality, as the resistance APPROACHES zero the current, from Ohm's Law, will APPROACH infinity. And therefore my reasoning is not incorrect in that sense.

    What is the relationship between relativistic currents and Ohm's Law?

    You have interpreted my question totally wrong. I know that superconductors have nothing to do with special (or general) relativity. However, I thought that as the resistance of materials approach zero, from Ohm's Law, the currents will approach infinity (I = V/R = V/0, as stated before)...

    What is the relationship between relativistic currents and Ohm's Law?

    I didn't know where to post this, but I figured since it has the word "relativity" in my question I would stick it here. V = IR. In a super conductor R = 0 and I = V/R = V/0 which is infinity. This implies an infinite number of charges per second flowing, and hence that the charges are...

    Matter to Energy: Kinetic + Rest Mass?

    Thanks for your response, that clears it up. You're right, this is a relativity forum and hence people may need to use a little more common sense, rather than others needing to be clearer.

    Matter to Energy: Kinetic + Rest Mass?

    If a particle is moving at some particular speed and then suddenly decays, is the energy released equal to the rest mass of the particle plus the kinetic energy it had before decay, or simply its rest mass?? Thanks.

    Special Relativity: just wanted a second opinion

    I gave B for Q2 and D for Q3. I said B because of Galileo who said that all velocities are relative, and D because (although I don't know much about it at all) the speed of light isn't necessarily "c" in a non-intertial frame of reference. They answers given were A for Q2 and C for Q3. What do...

    Special Relativity: just wanted a second opinion

    I didn't mean I wanted your opinion on my answers. I just meant I wanted a second opinion on what the answers should be for the questions.

    Special Relativity: just wanted a second opinion

    What would you suggest as the answers to the 2 attached multiple choice questions? My answers clashed with the answers provided and I stand by what I chose, and just wanted a second opinion. Thanks.

    Can a moving car's weight be accurately measured on a scale?

    Just a little thing, and something you may look into in the future: When you consider special relativity, speed DOES change mass! Very interesting stuff.

    What Determines Relativistic Momentum: Mass or Velocity?

    In a practice exam I just did for my upcoming high school mid-year, there was a multiple choice question and the two answers that seemed plausable were "relativistic momentum depends on the mass and velocity of the object" or "relativistic momentum depends only on the mass of the object". I...
