Answer:
An increase of 3,500 J
Explanation:
Given that,
Energy added by swimmer = 12000 J
Heat removed by the surrounding = 8500 J
We need to find the total change in energy. It can be calculated using the law of conservation of energy such as :
As the change in energy is positive, it means that there is an increase of 3500 J.
