Answer :
Final answer:
The battery delivers 27,360 joules of energy in the 52-hour interval.
Explanation:
To calculate the energy delivered by the battery, we can use the formula:
Energy (in joules) = Power (in watts) * Time (in seconds)
Given that the battery delivers 15 mA for 52 hours, we need to convert the current to amperes and the time to seconds. So,
Current = 15 mA = 15 * 10-3 A
Time = 52 hours = 52 * 60 * 60 seconds
Now, we can calculate the energy:
Energy = 15 * 10-3 A * 52 * 60 * 60 s = 27,360 joules
Therefore, the battery delivers 27,360 joules of energy in the 52-hour interval.
