i think the question asks when the switch was closed, i just dfon't know why P would be the higher potential when a back emf is induced by the inductor

Homework Statement While the voltage induced between the points P and Q is changing, which is the high potential end of the inductor? Explain your answer. P.S. sorry for the fail Paint job lol Homework Equations The Attempt at a Solution I know that in a DC circuit current flows from the...

Q: "If a curve with a radius of 85m is properly banked for a car traveling 65km/h, what must be the coefficient of static friction for a car not to skid when traveling at 95km/h?" [PLAIN]http://a4.sphotos.ak.fbcdn.net/hphotos-ak-ash4/215513_1974874979462_1470693940_32310002_1293630_n.jpg...

aaaahhhh thanks to both of you I understand now Thanks again

Hello I do not understand the answer given, i may be thinking too hard? Q: "What is the maximum acceleration a car can undergo if the coefficient of static friction between the tires and the road is 0.90?" A:"The static frictional force is the accelerating force, and so F(friction) =...
