Answer:
D.) perpendicular to the current
i am 100% sure :)
Answer:
<em>The amount of charge increases.</em>
<em></em>
Explanation:
For a capacitor that has its plates still connected to a battery, the voltage on the capacitor remains constant. If the distance between the two plates of this capacitor is decreased, the capacitance will increase, and then the charge on the plate will increase in accordance with the relationship
Q =CV
From this relationship, if V is held constant, then Q has to increase for C to increase also.
Answer:

Explanation:
According to Coulomb's law, the magnitude of the force (F) between two objects with the same charge(+Q), separated a distance (d) apart, is defined as:

Here k is the Coulomb constant. The charge on each object is doubled, that is
:

Answer:
I'm not sure but I think it's 4.5 v
