Two submarines are underwater and approaching each other head-on. Sub A has a speed of 13.9 m/s and sub B has a speed of 10.6 m/s. Sub A sends out a 1560-Hz sonar wave that travels at a speed of 1522 m/s. (a) What is the frequency detected by sub B? (b) Part of the sonar wave is reflected from B and returns to A. What frequency does A detect for this reflected wave?
a submarine Dakota is pursuing another sub the Rushing Water, it uses a sonic pulse at 2.10 kHz to find range to Rushing Water. the sonic pulse hits the Rushing Water and the echo is measured by the Dakota 0.75 s after the initial sonic pulse. the measured frequency of the echo is 2.110 kHz. what is the distance between the two submarines and what is the speed of the Rushing Water? Dakota speed is 15.5 m/s and speed of...
Question 1 Not completo Marked out of 1.00is approaching a school of fish, as shown in the figure below Dolphins emit clicks of sound for communication and echolocation. A marine biologist is monitoring a dolphin swimming in sea water where the speed of sound is 1522 m/s. The dolphin marine biologist dolphin school of fish The marine biologist measures the number of cicks per second to be 2460 Hz. The dolphin is swimming away from the stationary mane toogst at...
QUESTION 3 A sonar echo returns to a submarine 0.9 s after being emitted. What is the distance to the object creating the echo? (Assume that the submarine is in the ocean, and the speed of sound in ocean water is 1540 m/s) Express the numeral of your answer in SI units with 3 or more significant figures. QUESTION 4 Infrasonic waves have the frequencies in this range: Below 20 Hz Above 20 kHz 20 Hz -20 kHZ QUESTION 5...
