Answer:
By a factor 9
Explanation:
The intensity of a sound wave is proportional to the square of the amplitude of the wave:

where
I is the intensity
A is the amplitude of the wave
In this problem, the amplitude of the sound wave is increased by a factor 3:
A' = 3A
So the intensity would change by

So, the intensity would increase by a factor 9.
Answer:
i think its 1.5 m/s to the right?
Explanation:
Answer:
A
Explanation:
You are given Vi, Vf and t. The only thing left is a.
The particles in a solid are tightly packed and the particles do not move
The particles of liquid is less tightly packed and move with lesser kinetic energy than solids
The particles of gases are least tightly packed and the particles move around freely with the least kinetic energy than solids and liquids
