Please solve all with steps :(((((

In the following network of capacitors, C1 is 4 HF and C2 is 2 HF. A 24-V battery is connected to the network as shown. The switch Sis initially open. Find the charge on the C2 capacitor that is already connected to the two C1 capacitors; When the switch S is closed, find the charge on the same C2 capacitor. In the following circuit, find the currents (direction and magnitude) through the three resistors. 30 a1 = 65V In the following circuit, find the power dissipated in the 4-9 resistor
