Part 1
C. 10 Coulombs
Part 2
A. The strength of the magnet increased as the amount of current increased.
Explanation:
1. When a voltage is applied to these plates an electrical current flows charging up one plate with a positive charge with respect to the supply voltage and the other plate with an equal and opposite negative charge.
If the capacitors are connected by a conductor they must have equal potentials. If their charges are not +/- Q there will be a potential difference and charges will flow until they are +/- .
2. Based upon the results of the experiment which is graphed, an increase in current increases the number of paperclips picked up. The increase in current produced a stronger magnetic field from the electromagnet created. The ability to pick up paperclips testifies to the strength of the magnet and this strength is because of the current emitted to the coils which in turn magnetizes the nail
