The EMF does not depend on which of the following? A. The magnetic field strength
B. The number of electrons in the magnetic field
C. The velocity of the wire in the field
D. The length of the wire in the magnetic field

Select the three ways that the parallel-plate capacitor differs from a car battery.

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
