A simple RC circuit is shown below, where .50 MΩ and C= 1.50 μF. The capacitor has a charge of 90.0 μC before the switch is closed. The switch closes at 0 s.
A) Determine the time constant of the circuit
B) Determine the charge on the capacitor 3.00 s after the switch is closed.
C) Determine the time when the current through the resistor is 6,50 μA.
A rocket has a mass of 1.2kg and is acted upon by an impulse from the engine of 130.5 N s during the 2 seconds the engine is firing. Determine the average net force acting on the rocket while the engine fired?
