Answer:
The wave produced is a standing wave.
y' = [2ymax - kx] cos wt.
y max is maximum displacement, k is angular wave number, x is equal to the length L, w is angular frequency, t is time.
The time taken for the wave to travel to the ceiling and get reflected is given as:
t = 1/f = (2L)/nv. Where n =, 1,2,3, .... and v is wave speed, f is wave frequency.

Answer:
D. Sounds would be harder to hear.
Explanation:
if the ear canal is blocked then the sound waves cannot reach the ear drum thus we cannot hear clearly.
hope this helps please mark as brainliest:)
A structure has to be stable to be strong.
