What happens to sound waves from a moving source such as a car with its 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 the direction of shadow changes on turning around?
it doesn't. Only moving the light source does that.
What happens if the source of a sound is toward you at a high rate of speed?
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.
Do bee talk to each other?
No, they can communicate where a food source is but they can't actually talk to each other. Their body movement will tell where the nearest food source is and the direction they are doing the body movement is the direction the food source is in and the speed that their wings are moving is how big of a food source it is.
How to calculate apparent frequency the source is ahead and observer is behind both moving the same direction?
The apparent frequency does not depend on who is in front.
When does the Doppler effect happen?
The doppler effect happens when the source of a sound is moving. When it is moving towards you, it sounds louder and can have a different pitch and when the source is moving away, its a quieter more "far-off" sound. This is because when the source is moving, the sound waves are getting compressed in front of it due to relative velocity. Once the sound wave is made, it's speed is independent of its source. This is also how a sonic boom happens. At super sonic speeds, the sound barrier is broken which is the build up of all the sound waves created.
What is the Doppler shift equation?
Percentage(%)=(C+Vr)\(C+Vs) C is the velocity of waves in the medium; Vr is the velocity of the receiver relative to the medium; positive if the receiver is moving towards the source (and negative in the other direction); Vs is the velocity of the source relative to the medium; positive if the source is moving away from the receiver (and negative in the other direction).
What happens to convection currents if the heat source is removed?
The convection currents will eventaully stop because there is no heat to keep them moving.
What happens if a source of sound is moving toward you at a high rate of speed?
The waves compress which causes a lower tonal quality.
When the source of a sound is moving the sound waves spread out as it travels away from the listener As this happens what does the listener observe?
a lower-pitched sound
What lets you know that the source of a sound is moving toward or away from you?
When a sound-source moves toward you, its pitch gets higher and the sound gets louder. When it moves away, the pitch lowers and it gets quieter. The frequency change is called the Doppler shift.
