509% Part (b) Consider a 5.0om long wire of mass 10.0 g. The wire is suspended between the poles of a magnet as shown (end view of wire). When a 0.7 A current in the wire is turned on, the wire and magnet are attracted to each other. wire What can you learn about the magnet and the direction of the current through the wire with this information?

ww An AC voltage source is connected to a resistor, a capacitor, and an inductor, as shown above. (a) If the frequency of the voltage sine wave is very, very high, which component (R, C, or L) do you think will have the greatest average magnitude of current flowing through it? Which do you think will have the least? Why? (b) Same question as (a), but with an input voltage with a very, very low frequency.

A-10.0 nC point charge and a +20.0 nC point charge are 17.5 cm apart on the x-axis. Part A What is the electric potential at the point on the x-axis where the electric field is zero?
