Consider a two-state system (i. e. the hilbert space is two-dimensional) whose hamiltonian h has uormalized eigenstates lr) and l'2) with nondegenerate energy cigeivalues e, and ea, respec- tively. the same system has an observable q whose eigenstates are |φ+ (w) +№))and lp-) = ( v1)- ψ with nondegenerate eigenvalues λ+ and λ-, respectively. a) do h and q commute? b) express the eigenstates of h in terms of the cigenstates of q c) write h and q as explicit matrices in the [ivr)./2)) basis d) write h and q as explicit inatrices in the {lo+), io) basis. e) suppose the system is initially in the state |φ+). find the expectation values of h functions of time.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
