The internal resistance of a battery is relatively small when the battery is new but increases as the battery ages. When a new 12.0-VV battery is attached to a 100 ΩΩ load, the potential difference across the load is 11.9 VV. After the circuit has operated for a while, the potential difference across the load is 11.2 VV .By how much has the internal resistance of the battery changed?

i think the answer would 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.
