Homework Statement In the figure, a region with constant (externally produced) magnetic field is shown. A wire loop moves into the magnetic field. [Image Included] Question 1While the loop is moving into the region with the constant external magnetic field, the magnetic field inside the loop...

Using that equation I got Vd = 16e-6 * 0.0025 / 2.00 = 2.00e-8 m/s This answer was incorrect though.

Homework Statement A thin metal film of length 1.00 cm, width of 0.250 cm, and thickness of 29.0 micrometers is used to measure the Hall effect. A current of 2.60 A is maintained along the length of the sample. The Hall voltage of 16.0 microVolts is detected across its width, when a magnetic...

EDIT: I figured it out, thanks so much for the help!

Ok, so the charge on capacitor C1 would be... Q1 = 5.95μF/ 277 V = 2.14*10-8C and likewise the charge on C2 would be 6.859*10-9C I really don't have a clue what happens when they are reconnected though. My guess is that by using Q=CV I can take the sum of the charges, and then using...

Thanks for the reply, I am still a bit confused though. I thought the original charge on each capacitor would be half of the total charge of the equivalent capacitor. Therefore Qt = (C1 + C2)/V And the charge of each capacitor would be 1/2 Qt Am I on the right track so far?

Homework Statement Capacitors C1 = 5.95 μF and C2 = 1.90 μF are charged as a parallel combination across a 277 V battery. The capacitors are disconnected from the battery and from each other. They are then connected positive plate to negative plate and negative plate to positive plate...

Thanks GO1! Thats exactly what i was looking for. I've got the answers now :)
