16 is definitely wrong. I have since worked it. I = A n = m^-3 A = m^2 e = C = A*s V = m*s^-1 which gives you A = m^2 * A * s * m * s^-1 * m^-3 Can anyone help with 17? I don't even know where to start...

I have attempted two questions, see below. 1. The relationship between energy, E, and momentum, p, is E = P^2C^2 + M^2C^4 for a relativistic particle, Show that the equation is homogeneous 2. The current, I, in a wire is given by I = nAev where n is the number of electrons per unit volume, A...
