    High School If an atom was scaled up to the size of a sports oval with a diameter of 150m ?

    Well, that depends on the element you're looking at. Different elements have different ratios of atomic radius to nuclear radius (as you increase Z, you get different Coulombic forces as you add electrons, not to mention you add electron shells). I don't know the mathematical formula(s) to...

    Graduate Device that blocks waves of one phase, but transmits wave of opposite phase?

    Well, I'm not sure this answers your question properly, you may want to expand on the background idea of this question a bit more, but something to look into might be lasers and coherence. I'm under the impression that you're trying to figure out something to do with interference, though I'm...

    Finding work done in spherical coordinates

    Check the force along the path you are given (because it's really a line integral through a vector field), and it should become fairly simple to see why that is. Notice that your psi component didn't really change in the integral that mattered.

    How Do You Calculate Angular Acceleration and Time for a Turntable Platter?

    The roll without slipping is all you really needed. It means the larger wheel spins as fast as the smaller wheel (as if they didn't, one would be slipping past the other). This means their ANGULAR accelerations are both the same. The angular acceleration is just the change in their angular...
