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 10.9 VV .

Part A

By how much has the internal resistance of the battery changed?

Express your answer using two significant digits.
