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 :

$\Delta U=Q-W\\\\\Delta U=12000-8500\\\\\Delta U=3500\ J$

As the change in energy is positive, it means that there is an increase of 3500 J.
