Can you please help me with these questions? Thank you!!

33 A capacitor of capacitance 250 uF is charged by a battery of emf 12 V. The battery is removed and the capacitor is connected to a resistor of resistance 75 k$2 through which it discharges. Determine a the charge and b the current when the voltage across the capacitor is 6.0V. 34 A capacitor of capacitance 2.00 HF is charged by connecting it to a battery of emf 9.00 V. The capacitor then discharges through a resistor of resistance 5.00 MS. Determine at a time of t = 1.00 s: a the rate at which charge is leaving the capacitor plate b the rate at which energy is being dissipated in the resistor c the rate at which energy is being lost by the capacitor. 2.00 UF 5.00 MQ 35 Refer to Figure 11.47 on page 470. The input voltage is sinusoidal. a sketch a graph to show how voltage varies with time across i diode A ii diode B b suggest how the output can be made even smoother
