Question: The sketch shows two identical capacitors, connected in series with a battery. The battery has an emf of E = 10 V. When connected as shown, the combination of capacitors carries a total of q = 6.0 × 10-6 C.[A] Estimate the capacitance of the series combination of capacitors shown.Cs = _____________ units[B] Find øE – d A for the surface S1, shown in the sketch below. The surface encloses one plate of one of the capacitors. The answer can be left in terms of εor, but be sure to give the correct sign of the integral with your answer.øE – d A = ____________unit.[C] Estimate the capacitance of one of the capacitors.C = ___________units

Illustrate the force vectors with their tails at the origin of coordinate system. The orientation of your vectors will be graded. The exact lengths of your vectors will not be graded but relative length of one to the other will be graded.
A 170, 35.0 cm-diameter turntables rotate on frictionless bearings at 53.0. A 20.0 block sits at the center of turntable. A compressed spring shoots the block completely outward along a frictionless groove in the surface of the turntable.
A 260 wooden raft floats on a lake. When an 80 man stands on the raft, it sinks 5.0 deeper into the water. When he steps off, the raft vibrates for a while. What is the frequency of vibration.
An old trick to find out if a train is coming is to put your ear on the rails of the track. Why is this more effective than just listening for the sounds the train makes in air.
