"Amplitude" is the one property of the sound wave among the following choices given in the question that undergoes a change with an increase in its energy. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope the answer helps you.

Answer from: juiceyj9811

Amplitude

Explanation:

Sound is the form of energy which gives us the sensation of hearing.

Sound wave are mechanical waves and they propagates as longitudinal wave motion.

The speed of sound is maximum in solids and minimum in gases.

The energy of sound waves is directly proportional to the square of amplitude of the sound wave.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

Answer from: Quest

Velocity is the speed of an object in a certain direction so you'd need to know speed and direction
