she hears a strum breaking.
When you twang a ruler on the edge of a table, you create vibrations in the ruler. These vibrations disturb the surrounding air molecules, generating sound waves that travel through the air. The frequency of these vibrations determines the pitch of the sound you hear. Essentially, the ruler's motion converts mechanical energy into sound energy.
This may sound like a tautological answer. But ∞+1 comes after ∞. And ∞+2 comes after that. As long as what you define is mathematically consistent and makes logical sense, you are allowed to make up whatever number system and rules you want. Georg Cantor defined the ordinal numbers and transfinite arithmetic by making the + operator non-commutative. So 99+∞=∞ but ∞<∞+1.

Outerspace has no sound. This is because outerspace is essentially devoid of matter, and matter is required for sound. Sound is a physical phenomenon of a travelling pressure wave, and in space there is essentially no gas or media to transmit a wave.

Essentially it is the density and temperature of the air which determines the speed of sound therein.
Essentially, yes.
The volume of sound is determined by the amplitude of the sound waves. Higher amplitude corresponds to a louder sound, while lower amplitude corresponds to a quieter sound. Essentially, the energy in the sound wave affects the perceived volume of the sound.
A sound wave is essentially fast changing sound pressure. Longitudinal sound waves need a medium to travel through in order to exist.
If the wavelength of a sound wave increases, the frequency of the wave decreases. This means that the pitch of the sound would decrease. Essentially, the sound wave becomes stretched out, resulting in a lower pitched sound.
ocean waves have to do with water and sound waves have to do with sound
The Sustain pedal on a piano essentially prolongs the sound that has been played.
A null set is an empty set, or a set with no elements in it. Although that may sound pointless, its uses are similar to those of 0 in arithmetic.
Sound cannot travel through a vacuum as it needs a medium, such as air, water, or solid material, to propagate. In a vacuum, there are no particles for sound waves to travel through, so the speed of sound is essentially zero.
