if we r travelling in a car at the speed of sound what happens if we press the horn button?

Answer 1

We Don't know because nobody has ever survived the attempt.

Answer 2

If you are the driver (Or any one physically behind or in your car) the sound would be slightly lower in pitch but you should hear it just fine. If some one was in front of your car ,and you are driving towards them, they would'nt hear anything at all untill the car reaches them. This is becasue you are moving at the same speed that the sound is moving. Hence the sound reaches the person in front of you at the same time that your car reaches them.........hmm thats pretty scarry.

P.S. Its important to note that the speed of the sound does not change at any time during this event. Only the frequency and wavelength change. For instance, the speed of sound will not double (which seems to be the intuative answer) , becasue if the speed did doulbe then your car would never be able to catch up with it. Meaning that your car would always be behind the start of the sound wave, and the guy in front would hear the car first...turn to look...and then move out of the way..which will not happen as stated above.

Answer 3

Since you and the car are travelling at the same speed and the horn is in front of you, you will hear the sound as normal. But if the horn were behind you, all would be silent.

Answer 4

the two automobiles are gonna be pulverized right into a haze of atoms very almost immediately. there is not any way for the two to warn the different. Sound out of your horn can not attain the different automobile in time because of the fact your mixed last speed is lots quicker than that of sound. think of approximately lightning and thunder and why you spot the lightning formerly you pay attention the thunder. If the two automobiles have been heading in direction of one yet another quicker than easy speed neither might see the different in any respect because of the fact the actual automobiles are outrunning their easy. Now in case you prefer to get genuine technical approximately the two automobiles shifting quicker than easy the region could be that the two automobiles might have countless mass (..each and every of the mass interior the universe..) and it might have taken countless ability (..each and every of the flexibility interior the universe..) to get them as much as their velocities. yet then we are left with the question of the place are we going to return up with any ability to place into the collision because of the fact there is none left interior the completed universe. Spooky huh...?

Answer 5

it is to be noted that the speed of sound is only 330m/s but speed of light is 3X 10^8 m/s so by the time horn sound reaches ur ear u wud have already raced it and wud be travelling way ahead of this sound ............ what i mean to say is that u will not have a chance to hear this sound at all

Answer 6

May be I think that the sound will be heard by you continuosly even though you stop pressing horn. It will be heard by you until any any thing absorbs it or reflects it.
A star gift for you for asking an interesting question...

Answer 7

car will be travelling in the same speed.

Answer 8

as the horn i placed in front of the car...... so we will hear the sound quite faster but..... but we will not be able to recognize the difference.....

Answer 9

u will hear nothing as before the sound can travel to ur ears u will race away from the source of sound......... this is dopplers effect

Answer 10

If you are in an elevator going down at the speed of acceleration of gravity and drop the book from your hand then when it will touch the floor of elevator ?
