What do you expect the voltage across the resistor to be? Is it close?What do you expect the voltage across the inductor+capacitor combination to be? Is it close?How can the voltage amplitude across the capacitor and inductor (individually) be larger than the input voltage? Wouldn't this contradict Kirchoff's laws, which says that the voltages have to add up to the input voltage? [Can this happen for a DC circuit with a single power supply? If so, how? If not, what's different?]

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
