In a series circuit, the electrons passes through each component in order before returning to the cell. In a parallel circuit, there are different paths for the electrons to take so the current splits ...

Kinetic Energy (E_k) = 1/2(mv²).This can be rearranged such that, m = (2E_k)/v²we know from the question that E_k = 100 J and we know that v = 15 m/sso ...

Distance is a scalar, meaning it only has a magnitude. Displacement is a vector, meaning that it has both magnitude and direction. For instance, distance can state that I am "x" metres away f...

The De Broglie wavelength equation is as follows:

λ=h/p

We know the value of Planck's constant h and so to calculate the wavelength all we need is the momentum, which is equ...

The key to this question is to remember the Nyquist rate of a signal. This is the lowest sample rate which can be used for a signal without losing valid frequencies or gaining incorrect frequencies. Th...
