Answer:
1) Sound waves are stores as electrical signal in the digital recording.
2) the electrical signal of the digital recording is transcribed and sent to the voice coils.
3) the voice coil changes this electrical signal into varying magnetic fields.
4) The magnetic field pushes and pulls the diaphragm of the speakers.
5) the pushing and pulling of the diaphragm generates sound waves in the speaker.
Answer:
The pH of the solution increases.
Explanation:
Acetic acid is a weak acid, this means it does not dissociate completely in aqueous solution.
Sodium acetate on the other hand is a salt which dissociates to give acetate ions ad sodium ion.
Also, sodium acetate is the conjugate base of acetic acid. A mixture of a weak acid and its conjugate base is a buffer solution.
The mixture leads to a greater concentration of acetate ion, CH3COO-. shere is an increase in the pH of the solution.
So, when you are adding sodium acetate to a solution of acetic acid, concentration of acetate anions increases. Thus, there will be a decrease of hydronium ions resulting in pH increase.

Explanation:
Answer:
In an air compressor, a rotor spins, causing a piston to move up and down. When the piston goes down, freestanding air is pulled into a chamber. Then, the air is compressed and forced back outward as the piston rises back up.
Explanation:
Answer: C) size decreases
Explanation: Atomic radius values change as you move horizontally and vertically across the periodic table. In general, atomic radius or atom size decreases as you move from left to right.
