Answer:
C. Car A
Explanation:
if the answer is: which roller coaster car has the greatest potential energy due to gravity brainly
I am not sure if this is the answer you are looking for but a earthquake occurs when the plates shift.
Hope this helped.
The potential difference across 3 Ohm resistor is 20V.
The resistors are connected in parallel which means all the three resistances have a fully potential difference of 20V.
