9. The sirens of two ships "A" and "B" have a frequency of 200 Hz and sound simultaneously. The propagation speed of sound in air is 10°C. It is assumed that ship "A" is stationary and "B" is moving along the line joining them. The captain of ship "A" perceives a sound of 210 Hz frequency coming from ship "B", determine: a) If boat "B" approaches or moves away from boat "A". b) The speed of "B" with respect to ship "A".

1. Like most dolphins, "Sparky the Wonder Dolphin" uses echolocation (or sonar) by emitting high frequency "clicks" to locate objects in the water around her. Typical frequency of a dolphin's sonar click is 100 kHz, while the typical intensity of a sonar click at a distance of 1 m from a dolphin's head is 200 dB. The speed of sound in sea water is about 1520 m/s. If Sparky emits a sonar click that bounces off a school of tuna 20 km distant, a) how long must she wait to hear the reflected pulse, and b) what is the intensity in dB of the reflected pulse that she hears?
An ocean wave has a length of12 m. A wave passes a fixedposition every 3 seconds. What isthe speed of the wave?
A) A 6000.0 HZ sound wave is emitted by a stationary source. This sound wave reflects from an object moving 3.5 m/s toward the source. Calculate the frequency of the wave reflected by the moving object as detected by a detector at rest near the source.(Given speed of sound in air = 343.0 m/s)

4.(a) A French submarine and an American submarine move towards each other during maneuvers in motionless water in the Northern Atlantic. The French sub moves at speed of 55 km/h and the US sub at 75 km/h. The French sub sends out a sonar signal(sound wave in water) at 1,56 x 103 Hz. Sonar waves travel at 5470 km/h. i) What is the signal’s frequency as detected by the US sub? ii) What frequency is detected by the French sub in the signal reflected back to it by the US sub? (b) Compare red shift with blue shift.
21- a) An ambulance moving with a speed of V, m/s, produces a siren of frequency 416HZ, approaches an observer B, who is moving in the opposite direction with a speed of 26 m/s. If the frequency heard by the observer B is 656 Hz, and the speed of the sound is 342 m/s, calculate the A. Speed of the ambulance V, in m/s b) If now, the observer A is receding from the ambulance with the same speed as the observer B, calculate the Frequency of the sound heard by the observer A, in hertz:
