calculate current:

calculate equivalent resistance of circuit if powered by a 120V plug:​

real, smaller and upside-down.   so the answer should be b.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
