How is sound recorded

Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.

In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.

hope this helps

have a good day :)

Explanation:

sound is made up of waves in the form of vibrations in the air, and can be detected by the human ear. Using magnets analoque technology takes sound waves and turns them into electrical pulses. When a metal conductor is moved inside the magnetic field an electric current is produced in that wire.

Explanation:

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

ya the other dude is right
