Power is defined as the rate of transfer of energy and it is solved as b equals e over t where p is the power e is the energy transferred so it can be the form of work and p is the time in seconds in this problem a jogger generates heat energy at the rate of 800 watts if all this energy is removed by sweating that means this energy is going to be absorbed by the water in the body and then this water would evaporate in the form of and this water in the form of sweat would evaporate with we want to find the amount of sweat that evaporates after 1r.
00:34
So first is that let us find the amount of heat energy that is formed if the jogger exercises for this amount of time, which is 1r.
00:45
So from the equation of power, we can solve our energy as e equals p times t, where t is the amount of time in seconds.
00:55
So 1r is equivalent to 3 ,600 seconds.
01:05
So e is equal to the power, which is 800, multiplied by the time in seconds, which is 6, which is 3 ,600.

This gives us the heat energy generated in joules as 2880 ,000...
