The amplitude of a sound<span> wave </span>determines<span> its </span>loudness<span> or volume. A larger amplitude means a louder </span>sound<span>, and a smaller amplitude means a softer </span><span>sound</span>
object's weight is the independent of mass and gravity .
Weight = mass × gravity
The pressure of the air inside the balloon is higher than outside, and when you pop the balloon, the high pressure air expands quickly and makes a popping sound.
The minimum frequency is

while the maximum frequency is

Using the relationship between frequency f of a wave, wavelength

and the speed of the wave v, we can find what wavelength these frequencies correspond to:


So, the wavelengths of the radio waves of the problem are within the range 188-545 m.
