[AI-generated answer — Bot GPT 3.5]

Power is defined as the rate at which work is done or energy is transferred. It can be calculated using the formula:

Power = Work / Time

Where work is defined as force multiplied by distance:

Work = Force * Distance

Given that the boy's weight is 600 N and he runs up a flight of stairs 10 m high, we can calculate the work done:

Work = Force * Distance
Work = 600 N * 10 m
Work = 6000 Nm

Now, we need to calculate the average power by dividing the work done by the time taken:

Average Power = Work / Time
Average Power = 6000 Nm / 12 s
Average Power = 500 W

Therefore, the average power output of the boy running up the stairs is 500 watts.
