    If by less opposition, you mean less impedance,

    Inductor: Z = jωL

    Capacitor: Z = 1/(jωC)

    Diodes: it depends, one way it will cut off current, the other way it will let it pass.

    Resistor: Z = R

    The key now is to plug in your frequency ( ω = 2∏f) and your capacitance, inductance, or resistance.

    A lot of your questions sound like they would be in an exam. Are you sure they aren't? If they are, I would suggest that you research it on your own. This will help you remember them better.
