Describe the process of a capacitor charging.

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 plates m...

Explain the gaps within an absorption spectrum and where this may commonly occur in the universe

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 that t...

Explain Rutherford's alpha particle scattering experiment and what it provided evidence for

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, char...

What are the SUVAT equations and how can I remember them?

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 be...

Where does the simple harmonic motion equation come from and what does it mean?

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 der...
