To find:
Which property of mechanical waves determines the energy carried by them?
Explanation:
The mechanical waves are the waves that carry energy from one point in a medium to another. The mechanical waves require a medium to travel through.
The property that determines the energy that the wave carries is the amplitude. The amplitude of a wave is the maximum displacement of the wave from its mean position.
The energy carries is directly proportional to the amplitude of the wave.
Final answer:
Thus the correct answer is option A.
