<u>Answer:</u> The correct answer is Option 3.
<u>Explanation:</u>
Amplitude of as sound wave is defined as the extent to which the air particles are getting displaced.
Speed of the sound wave is defined as the distance traveled by the sound wave per unit time and is not related to the amplitude of a sound wave.
Wavelength of the sound wave is defined as the difference between two crests or troughs.
Loudness of a sound wave is defined as the size of the vibration which are produced by it. This is closely related to the amplitude of the sound wave.
Pitch is defined as the sensation of the frequency. Higher the frequency, the pitch is also high and vice-versa.
From the above information, the amplitude of a sound wave is most closely related to the sound’s loudness.
Hence, the correct answer is Option 3.
As the chemical bonds are broken, the positions of electrons change, resulting in a product with properties that are different from the properties of the reactants. Various temperatures and catalysts are needed for different chemical reactions to occur. <span>During a chemical reaction, new substances are produced as existing bonds are broken, atoms are rearranged, and new bonds are formed.</span>
<span>We use m/s for the velocity, and m2/(V·s) for the </span><span>mobility.</span>
I think it was either Robert Hook or Anton Van Leevwen Hoek
