A capacitor circuit: C1 and C2 are in series, C3 and C4 are in series, and these two collections 1-2 & 3-4 are in parallel with each other. C1 =1.00pF , C2 = 0.600pF, C3 = 3.20pF and C4 = 2.40pF. What is the total charge stored in the system if it is connected to a 5.07V power supply?

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
