We know that V=E/Q Where V is the PD, E is the energy, and Q is the charge.
Substituting in the values gives V=48/4=12
Therefore the PD across the circuit is 12V
It would have to be a solid so the answer would be A.
Answer:
The direction of the induced magnetic field should be pointing towards the screen.
Explanation:
Because the magnetic field is decreasing, and if we use Len's law, the induced current will increase the external magnetic field. For this increase to occur, said magnetic field produced by the induced current must be pointing towards the screen.
