    pikpobedy liked post by mayflow On thread : capacitors in series and parallel
    Capacitors in some ways in series and parallel circuits act very differently than resistors do. Capacitors absorb and slowy release electric charges, where resistors simply reduce current flow. (In...

    Yup; it's precisely the point made in the other thread about potentials and voltage dividers. Kirchhoff's "laws" (note the double-h in Kirchhoff; it's one of the most misspelled names in all of...

    That makes no sense at all. Either something is true or it's false. It can't be both. I most certainly can dismiss it. Especially since I'm right and he's wrong. This most certainly not a...

    Write down the equations for conservation of energy and conservation of momentum. (The problem is one dimensional). The two unknowns are the before and after velocities of the 2 kg. block. The...

    pikpobedy liked post by Jilan On thread : Why is a electric field induced by a varying magnetic field, non-conservative?
    With static charges the electric field can be described as the gradient of a scalar. It is therefore irrotational. The work done in moving a charge through the field is independent of the path taken...

    Atmospheric pressure is what keep the water liquid at atmospheric temperature. It is required for the water to stay in that glass anyway. The atmosphere pressure is part of the experiment, but the...

    In a no air environment, I get 24mm for the Equator scenario under "real" conditions. Here's the basic steps: Upon release, the object follows an elliptical trajectory with the Earth's center at...

    pikpobedy liked post by tk421 On thread : Dirac and Anderson
    It's not a daft question at all. The short answer is that we don't know if some antimatter galaxies exist. However, we can say that if there are indeed antimatter galaxies, they must be very far...

    No, inside the enclosed compartment, the observer is not moving relative to the air, which is moving with the train. The motion of train relative to the tracks is irrelevant, only the motion of the...

    You may want to consider introducing another variable, T, the tension in the string.

    We may model this as a long elastic cylinder containing a massive fluid. At the top and bottom are equal diameter pistons. There is a sustaining force on each piston to keep it from moving. ...
