<span>In a correctly balanced chemical equation, there are exactly the same number of atoms for each element found on both side of the equation (that is, in the reactants and the products).
No new atoms were made. None were destroyed. Matter was conserved.</span>
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.

The speed stops as it hits the girls hand but speed reduces as it reaches her hand and increases at the beginning of the movement
Answer:
20 m
Explanation:
Given:
v = 0 m/s
a = -10 m/s²
t = 4 s / 2 = 2 s
Find: Δy
Δy = vt − ½ at²
Δy = (0 m/s) (2 s) − ½ (-10 m/s²) (2 s)²
Δy = 20 m
