comment What point of application of force ensures more acceleration in a rod?
@Carl: But it does. Your view is wrong. 1 N to the right applied anywhere on the rod will cause the same accelleration of the center of mass to the right.

comment What point of application of force ensures more acceleration in a rod?
@Carl: It makes no sense to say that some of the "translational" is in the form of any kind of momentum. We are talking about forces and accelleration here. Momentum was never mentioned. In any case "translation" specifically excludes rotational components.

comment Electrostatics - Inserting a brass plate between two charges
@garyp: Brass is a pretty good conductor (has low bulk resistivity). Since there is no current flowing, it is a "perfect" conductor for this purpose, meaning the potential will be equal everywhere on its surface. Yes, the field shape will also change. I'm adding to my answer accordingly.

comment Why does a string remain taut in circular motion
You are asking multiple questions on circular motion, the answers to which are largely the same. Try to understand one of them before asking others. Once you understand one, the others should make sense.

comment How much does the sound definition vary during an LP (Vinyl)?
@Carl: Not insane at all when you think back to the beginning of CDs. They were originally designed for storing audio as a replacemnt for vinyl records. The data stream would be used continuously at a fixed rate. Large buffers to hold ever more data that was read but not yet played back would have been too expensive and large. Or, a constant data rate at varying track speed would have wasted density. The motor is there with speed control anyway. Making it controllable at various speeds adds little extra cost or complexity.

comment How much does the sound definition vary during an LP (Vinyl)?
@Carl: It's not a issue of changing the clock. The issue is maximum data per DC area but still allowing real time playback of audio at the same data rate without the frequency changing.

comment Can an LC oscillator be used to generate visible light?
@daniel: I didn't say optical resonance is unfeasable. I only addressed the question, which was about a lumped L-C resonant circuit. We may yet some day be able to create resonant cavities at the few 100 nm scale, but this is not what the OP asked about.
