Which of the following statements is false?
question 5 options:
a: destructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out.
b: when the crest of one wave overlaps the crest of another, their individual effects add together, which is constructive interference.
c: constructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out.
d: for sound waves, destructive interference results in lower volumes.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
