The ball in someone's hand is a balanced force because the object is staying in motion and is not changing at all so its evenly balanced, if its swinging back and fourth it is in motion and it wont stop till it becomes unbalanced, if the ball is just being held above the ground yes its balanced because nothing Is happening to it, its basically like a balance scale, if both sides are even and equal, than nothing will happen because there is no side that has more or less its equal so that's why its balanced, in order for it to be unbalanced it has to be brought upon unbalanced forces.

Explanation:
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.
