Which wave property decreases as you get farther away from the source of a sound?
Intensity
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Amplitude is intensity. It refers to the strength of a sound wave, which the human ear interprets as volume or loudness and if you decrease the amplitude you also decrease its intensity.
What happens to the volume of a sound wave as its amplitude decrease?
You mean by the word 'volume' the intensity of sound wave. Intensity is directly proportional to the square of the amplitude.
When the volume is loud does it vibrate more or less?
The higher the volume of sound, the bigger the vibrations. This is because more and bigger sound waves are being produced by the source of sound.
How is the intensity of a sound related to the distance between the source and the receiver?
The intensity of a sound will decrease according to an inverse square law.

Intensity
How does turning up a stereo increase the volume of the sound that is heard?
speakers vibrate farther

What is an apparent in frequency of a sound source that moves relative to an observer?
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.

Why does the loudness of a sound wave decrease as the wave travels away from it source?
The energy in the sound's vibration dies down, until it is no longer audible.

What is a diminuego in music?
Did you mean a diminuendo perhaps? A diminuendo is a decrease in volume or sound usually indicated by an elongated > symbol.
What the function of speaker?
A speaker is an audio output device that is used to relay sound from a source. The speaker's volume can be controlled from the source.
What do you call the occurrence of a sound getting louder as it approaches and quieter as it travels away?
It is called sound spreading. The sound wave is strongest at the source and the wave spreads out as it is farther away
