Could someone please help me with these physics questions? A quick explanation is only needed with the answer as I do not want you to spend to much time

(1) (20 pts.) Consider the circuit shown in the figure. The battery has emf of 72.0 V and negligible internal resistance. R2 = 2.00 0, C1 = 3.00 MF, and C2 = 6.00 F. After the capacitors have attained their final charges, the charge on C1 is Q1 = 18.0 MC. R1 W 3 R2 C1 C2 (a) What is the final charge on C2? (b) What is the resisitance R1?(2) (50 pts.) In the circuit shown in the figure, three identical light bulbs are connected to a flashlight battery. (a) How do the brightnesses of the bulbs compare? (b) Which light bulb has the greatest current passing through it? (c) Which light bulb has the greatest potential difference between its termi- nals? (d) What happens if bulb A is unscrewed (clearly bulb A goes out, but what happens to the brightness of bulbs B and C)? (e) What happens if bulb C is unscrewed (clearly bulb C goes out, but what happens to the brightness of bulbs A and B)? + B
