Problem-2: m Submarine A is chasing submarine B at a depth of 250 m. Submarine A is travelling at a speed of 10" while submarine B is т travelling faster at a speed of 12- 1200". Submarine B sends out a sonar ping at 1 kHz. Assume that the speed of sound at this depth is т a) What frequency of sound hits submarine A? (Answer:982 Hz) b) What would the frequency be if submarine B was moving at double its speed? (Answer:972 Hz)
An ambulance with a siren emitting a whine at 1770 Hz overtakes and passes a cyclist pedaling a bike at 2.61 m/s. After being passed, the cyclist hears a frequency of 1758 Hz. How fast is the ambulance moving? (Take the speed of sound in air to be 343 m/s.) Number i Units
Sound travels at an estimated speed of 344 * m/s c a sound wave has a frequency of 2500 HzWhat is the distance between the crests of each wave?
Because of the Doppler effect, the sound heard by an observer listening to a moving ambulance siren, compared to what the observer would have heard if the observer and siren were both at rest... will have a lower pitch if the ambulance siren is moving towards the observer. will have a longer wavelength if the ambulance siren is moving towards the observer. will have a lower frequency if the ambulance siren is moving towards the observer will have a higher frequency if the ambulance siren is moving away from the observer. will have a higher frequency if the ambulance siren is moving towards the observer.
Using the illustration above, determine the frequency and wavelength gathered from sound propagation occurring in stainless steel, you can consider the speed of sound in steel to be 5790 m/s.

A train whistle 2000 Hz sounds higher or lower in frequency depending on whether it approaches or recedes the observer. The difference between the two will be heard at the moment the train passes the observer. Calculate this difference for a train moving at a speed of 180 km/h. Take the speed of sound in air to be 330 m/s. State answer in hertz to the newest tenth of a hertz
