An ambulance traveling eastbound at 124.0 km/h with sirens blaring at frequency of 6.00 x 102 Hz passes cars traveling in both the eastbound and wesbound directions at 53.0 km/h. (Assume the speed of sound is 345 m/s.)  (a) What is the frequency observed by the eastbound drivers as the ambulance approaches from behind? (b) What is the frequency observed by the eastbound drivers after the ambulance passes them? (c) What is the frequency observed by the westbound drivers as the ambulance approaches them?  (d) What is the frequency observed by the westbound drivers after the ambulance passes them?

A bat traveling at a speed of 18.1 m/s sends out sound at a frequency of 48.2 kHz, can 'see' objects due to echolocation. What frequency would the bat hear returning from a stationary wall in front of it? (assume the speed of sound in air is 343 m/s)

Please explain how you got the answer for this, thank you so much!

While sitting next to a road on a calm, warm 27.9ºC evening, you see an ambulance's lights flashing in the distance coming towards you. You hear a frequency of 140 Hz. However, you know that ambulances have sirens that emit sound at 130 Hz. How fast is the ambulance approaching you, in m/s?

Sound waves are emitted isotropically (that is, with equal intensity in all directions) from a source. The intensity of the waves 3.00 m from the sourceis 2.60x10 -4 W/m 2. Assuming the energy of the waves is conserved, what is the power of the source?

Ocean waves with a wavelength of 40.0 m travel at 5.00 m/s towards a boat at sea. Determine the number of times the boat bobs up and down per minute as a result of encountering the waves.

A fire engine siren emits sound at 1260 Hz. The fire engine is driving down the street toward you at 29 m/s. (The speed of sound in air is 343 m/s.) What frequency sound do you hear? What frequency sound do you hear after the fire engine passes you?

While sitting next to a road on a calm, warm 27.9ºC evening, you see an ambulance's lights flashing in the distance coming towards you. You hear a frequency of 150 Hz (you have a very keen ear!). However, you know that ambulances have sirens that emit sound at 140 Hz. How fast is the ambulance approaching you, in m/s

If the wind were blowing at 25.0m/s in the same direction you are driving, what frequency would you hear?
