If a 1.5V AA battery is connected both ends together by a copper wire of 7cm long and 1mm diameter, what will be the power loss? (Resistivity of Cu = 1.72x10^-8)

There are many types of AA battery cells. There are also rechargeable ones. You forgot to say which one.
A lithium non-rechargeable AA battery cell made by Energizer has a current limiter inside to prevent a Lithium fire. The datasheet shows an excellent output of 1A and says 3A is fine and 5A can be in pulses.
A new Ni-MH cell can produce 10A when shorted and a Ni-Cad can produce more. The internal resistance shown on Energizer's datasheet for their Ni-MH cell is 30 milli-ohms.
