A bat flying at 17.1 m/s (ground speed) emits a 503 Hz sonar ping. The sound returns after 1.302 seconds at frequency 575 Hz. Assume the Speed of Sound in this type of air is 343 m/s. Determine the Velocity of the object, in m/s relative to the ground. Take "moving away" as Positive.
need help selecting correct answer 15. A submarine moving at 8 (m/s) emits sonar at a frequency of 1400 (Hz). A dolphin moves towards it at 9 (m/s). If the speed of sound in water is 1533 (m/s), what is the frequency detected by the dolphin? a. 1356 (Hz) b. 1385 (Hz) d. 1432 (Hz) c. 1416 (Hz)
A stationary source emits sound with a frequency of 1250 Hz. If the speed of the sound is 343 m/s, what frequency is heard by an observer approaching the source with a speed of 25 m/s? Please show all equations and work in detail. Write clearly please. I always rate and will rate, ty :) <3 Have a great day
9. An ambulance truck emits a sound with a frequency of 800 Hz. (the speed of sound in air at 20 Celsius is 343 m/s). (a) What is the frequency detected by a stationary observer if the ambulance truck moving 30 m/s toward the observer? (b) What frequency will b detected if the ambulance is moving 30 m/s away from the observer?
A dolphin has a sonar system that emits sounds with a frequency of 2.0×105Hz. The speed of sound in water is 1484m/s. Determine the period of the wave. T=? Determine the wavelength. λ =
1. A source moving with a speed 37 m/s, emits a sound wave with a frequency f = 377 Hz. Determine the frequency detected by a stationary observer if the speed of sound is v = 343 m/s and the source is moving towards the observer. 2.A stationary source, emits a sound wave with a frequency f = 428 Hz. Determine the frequency detected by an observer moving towards the source with a speed v = 43 m/s, if the...
Let the speed of sound be 340 m/s. A source emits a sound of 327 Hz. It is moving towards the right with a speed of 39 m/s and approaching an observer who is moving towards the left with a speed of 36 m/s. What is the frequency heard by the observer? Enter an integer.
019: A source emits sound with a frequency of 1000 Hz. An observer is moving at 160 m/s toward the source, which is stationary. The speed of sound is 340 m/s. The frequency heard by the observers is:
Question 7 3.6 pts A source emits sound with a frequency of 16,246 Hz. Both it and an observer are moving toward each other, each with a speed of 141 m/s. What frequency (in Hz) does the observer hear? Round your answer to the nearest whole number.
1. A bat emits a sound at a frequency of 12 kHz as it approaches a wall. The bat detects beats such that the frequency of the echo is 860 Hz higher than the frequency the bat is emitting. The speed of sound in air is 340 m/s. The speed of the bat is closest to 2. A supersonic plane passes overhead at a speed of 823 m/s. If you hear the sonic boom (shock wave) 4 s after the...
