Acapacitor is charged to 8.0×10−4 c , then discharged by connecting a wire between the two plates. 35us after the discharge begins, the capacitor still holds 14 % of its original charge.
what was the average current during the first 35us of the discharge?

Which type of current is produced by a wire breaking magnetic field lines and changing the polarity? a. alternating b. direct c. straight d. alternating and direct

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?
