At first, there is a potential difference between the two plates of the capacitor equal to the potential difference between the two battery terminals. This causes electrons to build up on one of the plate...

The gaps within an absorption spectrum occur when the light that is measured has passed through a medium that has absorbed some photons. The photons that the medium absorbs are specific to the element tha...

The experiment involved firing alpha particles at thin gold foil, where the number of alpha particles scattered at various angles were counted using a detector. This provided evidence for the existence, c...

The SUVAT equations for motion are as follows:v = u + at s = ((u + v)/2)t s = ut + (1/2)(a)(t^2) s = vt - (1/2)(a)(t^2) v^2 = u^2 + 2asThe last 3 equations can be derived from the first two, but will also...

We know that the displacement, x, is described by the equation x = Acos(ωt + Φ), where A is the amplitude of oscillation, ω is the angular frequency and Φ is the phase shift. The velocity, v, is the time ...
