Which characteristic of a sound wave is directly related to the loudness of the sound?

a(amplitude

b(pressure

c(wavelength

d(frequency

The correct answer is -

a) amplitude.

Amplitude of a sound wave corresponds to the loudness or intensity or volume of sound.

This means that large amplitude means the energy carried by sound waves is higher, producing higher vibration and thus large intensity of sound is produced.

Thus, amplitude is the right answer.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
