afrequency of the same as siren frequency as ambulance is the source and the observer this is not Doppler effect problem
Bcoz the name written in opposite direction looks on the correct direction when viewed through the mirror so that is the reason…..if a vehicle going in front of the ambulance can read it correctly and give a way to go a head
This is the doppler effect. If an ambulance is driving towards Jon, the sound waves are tightly stacked in front of the ambulance and are heard by Jon at a high frequency (high pitch). But behind the ambulance the sound waves are lagging because the ambulance is driving away from they sound waves (they are moving in the opposite direction) thus if Jon was standing behind the ambulance the frequency heard would be low (low pitch). The actual sound an ambulance makes is actually obnoxious, and if 100 of them drive by someone's apartment each day, it will make their head hurt and they will often think about why ambulances are so annoying.
Actually, you AND the coin are travelling at the same velocity as the plane. Therefore, when you flip it up it will come straight back to you and not into the guy behind you...as long as your throw is straight up in the air, of course. This is called relative velocity: the coin is traveling at a horizontal velocity of zero RELATIVE TO THE PLANE, but it is travelling at 400km/h (or whatever the plane is travelling at) RELATIVE TO THE GROUND.
The word "Ambulance" is printed backwards on the front of the ambulance so you can read it in the mirror the right way around
Technically a driver is not allowed to break any traffic laws to get out of the way of an ambulance, as such she should not have run the red light. If the ambulance had its lights and sirens on, then you are both at fault since you both should have pulled over.
150 meters
If you are traveling east there is no way Texas can be in front of you and NY behind you.
If you are facing north, the direction behind you would be south.
I don't know the details but most likely the vehicle that struck you is at fault if he/she was traveling in the same direction and lane behind you.
Since momentum (force in motion) is a measurement of mass times velocity, a heavier object traveling at the same speed as a lighter object will have more force behind it.
Well first of all, you don't. No object that has any mass when it's sitting still will ever travel at light speed. To answer your question in general: If you're sitting inside a spaceship, sipping a cup of coffee and surfing the web, and you decide to take a break from your back-breaking labor and step outside for a few minutes, then the moment you're outside, you continue traveling at the same speed and in the same direction that the ship was when you let go of it. If the ship is traveling with constant velocity ... constant speed in a straight line ... then you seem to float motionless next to it, because your speed and direction are exactly the same as the spaceship's. If the ship is accelerating, then you keep the speed and direction that you and it had when you let go, and the ship goes on its own merry way, leaving you behind, beside, or ahead.
If the ambulance isn't using its lights and sirens, just follow normal traffic laws. If it is, you'll need to pull over to the side of the road and wait for it to pass.
