Answer:
In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.

Explanation:
The speed of sound in air to be 343 m/s.
Given:
distance 'd' = 5 m
L = 12 m
It can be concluded that path difference must be equal to half of the wavelength when person is observing destructive interference'y' at 1 m distance from the equidistant position
Since
λ/2 = yd/L
λ/2 = (1 x 5)/12
λ = 0.833m
Frequency of the sound is given by,
f = v / λ => 343 / 0.833
f=411.6 Hz
I would think something like fire or a torch because that seems like it means heat or maybe a campfire picture

Explanation:
Solving Equations by Isolation
We have this equation:
Let's solve it for w step by step. First, we flip both sides
Subtracting 2Lh in both sides
Simplifying
Factoring w
Dividing by (4l+6H)
Simplifying by 2:
