Answer:
The time for which the flashlight last is 5.23 hours.
Explanation:
Given that,
One AA battery in a flashlight stores 9400 J, E = 9400 J
Power consumed by the LED flashlight bulbs, P = 0.5 W
We need to find the time for which the flashlight last. The power of a device is given by the energy stored per unit time as :



t = 18800 seconds
or
Since, 1 hour = 3600 seconds
t = 5.23 hours
So, the time for which the flashlight last is 5.23 hours. Hence, this is the required solution.
It can be said that the change is a chemical change. The green substance on the surface is copper oxide. It is a compound composed of the copper of the statue and the oxygen in the air.
