If it attractive it has opposite pole and if it repulsive it has same pole
Answer:
A
Explanation:
I only think its A because of the gravity part...sorry im not good at explaining
Near the surface of reflection, reflected wave may interfere with incident wave leading to production of constructive and as well as destructive interference. This in turn, can result to resonance as well as enhancement of the sound intensity as the waves of reflection adds to incident wave. Therefore, the girl would higher intensity of reflected waves as compared to incident waves.
Therefore, statement A is correct.
