An uncharged capacitor and a resistor are connected in series to the battery as shown in the figure below, where V0 = 12 V, C = 5 µF and R = 800kΩ. Find the time constant of this circuit, the maximum charge on the capacitor, the maximum current in the circuit and the maximum energy stored in the capacitor.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
