I fear you're confused - BUT : The Doppler effect is similar for both sound waves and electromagnetic radiation (light, radar).

What happens to the sound waves from a car with the horn honking when the sound waves are moving in the same direction as the car?
this is called Doppler effect and the velocities add, creating a higher sounding frequency.
Is Doppler effect in sound symetric or asymetric?
Doppler effect in sound is asymmetric. This means the change in frequency depends on whether the source is in motion or observer is in motion even though relative velocities are same in both cases. Doppler effect in sound is asymmetric because sound is mechanical wave requiring material medium and v, v0, vs are taken with respect to the medium. .Doppler effect in light is symmetric because light waves are electromagnetic (do not require medium)
Who discovered the red shift in stars the same effect that causes sound waves to change pitch as an object moves towards or away from an observer?
Doppler.
What happens to the sound waves from a moving source such as a car with a horn honking when the sound waves are moving in the same direction as the car?
The wavelength is compressed by the additional velocity of the car, so the frequency heard is higher than that generated in the horn. It's known as the Doppler Effect.

Why a siren changes pitch as it approaches and passes us?
This is called the Doppler Effect, a physics phenomenon that makes the sound of an approaching siren in an ambulance appear to be higher pitched as well as louder, but starts to immediately drop in intensity and pitch as it moves away from you. This is due to the apparent "compression" of the waves as they approach the observer (increases frequency), followed by "stretching" of the waves (decreases frequency) as they move away.
When a sound source moves towards you what happens to the wave speed?
It is called the Doppler Effect. When the source of waves approaches you (can be any type of waves - mechanical, electromagnetic like light etc.), the wavelength gets smaller and frequency higher. So when a car approaches you, you hear higher tone than when it departs.
Is the Doppler effect the same as a reflected wave?
No. The Doppler effect is an apparent change in frequency, due to movement, away from towards the observer.
A Doppler effect occurs when a source of sound moves?
The "change in sound" refers to a change in frequency. If (for example) you move compared to the sound source, then more, or less, wave crests may pass you every second, depending in which direction you move. It's best to check an article on the Doppler effect (for example, in the Wikipedia); with an illustration or animation, it is actually quite intuitive why this happens.
Is collecting sound the same as captureing sound waves?
Sound waves are what make up sound (sound waves=sound) so I would suppose so.
Why is a bow wave produced when a wave source moves?
Like the Doppler effect, the source of the waves is moving, this time in the same direction as the wave front and therefore catching up to the waves that were produced earlier, resulting in a bunching up effect of waves in front of the source and a spreading out of wave fronts behind the source. Does this look like a bow to you>
