Answer 1

Верный ответ     40 Вт       )))))

Answer 2

Calculating Heart Power

To calculate the power of the heart, we can use the formula:

Power = Work / Time

Given that the heart does 20 J of work with each contraction and makes 120 contractions per minute, we can calculate the power of the heart.

Calculation

Using the given values: - Work (W) = 20 J - Time (T) = 1 minute = 60 seconds - Contractions per minute = 120

We can calculate the power using the formula: Power = Work / Time

Substituting the values: Power = (20 J * 120) / 60 s

Power = 40 J/s

So, the power of the heart during the competition is 40 watts.
