Q: The graph of a capacitor in a circuit discharging is most similar to which of the following graphs?
A		A graph of velocity vs time of a racecar decellerating at a constant rate
B		A graph of displacement vs time of a runner who makes one revolution around a circular track
C		A graph of power vs current in a circuit with constant voltage
D		Potential energy vs time of a spring which is released from a stretched position and returns to a state of zero displacement
