A submarine’s sonar emits a sound with a frequency of 875 Hz. The speed of sound in seawater is about 1500 m/s. If you measure the frequency of the sound to be 870 Hz, what is the velocity of the submarine?
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 dolphin (Dolphin A) is swimming under the ocean at a speed of 4.87 m/s, emitting sonar sound wave at a frequency of 1222 Hz. The speed of sound waves under the ocean is 5518.8 km/h. Another dolphin (Dolphin B), located away is such that the two dolphins move towards each other. If Dolphin B is moving at 7.31 m/s, calculate the frequency that would be detected by a receiver attached to Dolphin B as the two fish swim towards...
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.
A dolphin in seawater at a temperature of 25°C emits a sound wave directed toward the ocean floor 314 m below. How much time passes before it hears an echo? (The speed of sound in ocean water is 1533 m/s.) s
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...
Question: A diver underwater sees a dolphin swimming towards him with a speed of 7.257 m/s. The diver gets excited and swims towards the dolphin with a speed of 11.994 m/s. The dolphin sees the diver and emits a call with a frequency of 22.73 kHz. Assume that the speed of sound through the water is 1521 m/s. Part 1) What frequency does the diver detect coming from the dolphin? f= kHz Part 2) The sound is reflected off the...
A sound source emits sounds of frequency 210 Hz that travel through still air at 340 m/s. The listener moves at 70 m/s relative to still air toward the stationary source. What is the wavelength of the sound between the source and the listener? (not 1.286 or 264.39)
Horseshoe bats (genus Rhinolophus) emit sounds from their nostrils, then listen to the frequency of the sound reflected from their prey to determine the prey's speed. (The "horseshoe" that gives the bat its name is a depression around the nostrils that acts like a focusing mirror, so that the bat emits sound in a narrow beam like a flashlight.) A Rhinolophus flying at speed vbat emits sound of frequency fbat; the sound it hears reflected from an insect flying toward...
As a bat flies toward a wall at a speed of 6.0 m/s, the bat emits an ultrasonic sound wave with frequency 30.0 kHz. What frequency does the bat hear in the reflected wave? Ship A is traveling 20 m/s due east. Ship B is traveling 15 m/s due west away from Ship A. Ship A sounds a horn with a frequency of 1500 Hz. What frequency does an observer on Ship A hear in the reflected wave from Ship...
