Answer:
The transverse displacement is
Explanation:
From the question we are told that
The generally equation for the mechanical wave is

The speed of the transverse wave is 
The amplitude of the transverse wave is 
The wavelength of the transverse wave is 
At t= 0.150s , x = 1.51 m
The angular frequency of the wave is mathematically represented as

Substituting values


The propagation constant k is mathematically represented as

Substituting values


Substituting values into the equation for mechanical waves

Answer:
65 years
Explanation:
The arc that ends at 4000 Hz intersects the 20 db hearing intensity at 65 years.
Hello!
<span>The type of interference that increases the energy of the resulting wave is called constructive interference. The type of interference that results in a loss of energy is called destructive interference.
When two or more waves are in the same medium, they can cross at a given point, where interference happens. When the two waves are in phase, the resulting amplitude in the point of interference is maxed. This is called constructive interference.
When the two waves are in opposing phases, the resulting amplitude in the point of interference is minimized. This is called destructive interference.
Have a nice day!</span>
B. The reference point is the 0 of a straight line description. Left of it would be negative and right of it would be positive.
