Answer: Constructive interference
Explanation: Just took the test
The diagram shows destructive interference between two waves, resulting in a smaller amplitude wave.
The type of wave interaction shown in the diagram is destructive interference.
In destructive interference, two waves combine and create a new wave with a smaller amplitude. This occurs when the crests of one wave align with the troughs of another wave, causing cancellation.
In the diagram, wave A and wave B are out of phase, meaning their crests and troughs do not align. When they combine, the resulting wave has a smaller amplitude than either individual wave, indicating destructive interference.

Answer: 90 degrees
Explanation:
The projectile will have the greatest air time and height when the launch is the most vertical. At 90 degrees, the launch is all vertical.
Answer:
Explanation:
Case I:
initial velocity, u = 0 m/s
Final velocity, v' = v Sinθ /g
Height = h
acceleration = g
Use third equation of motion, we get
. ... (1)
Case II:
initial velocity, u = v1
Final velocity, v = v2
height = h
acceleration due to gravity = g
Use third equation of motion, we get
Substitute the value of h from equation (1) ,we get
