Hel 1. What could you predict about the number of magnetic domains
and the strength of a magnet?
A. More aligned domains produce a stronger magnet.
B. The number of domains doesn't affect the strength of
the magnet.
C. Fewer aligned domains produce a stronger magnet.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
