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 speaker and microphone are attached to a cart moving toward a wall at speed LaTeX: v v m/s. The speaker sends out a constant tone, 236 Hz. The sound reflects off the wall and the reflected wave is detected by the microphone to have frequency 277 Hz. Taking the speed of sound in air to be 343.9 m/s, with what speed does the cart approach the wall? Give your answer to the nearest 0.1 m/s.

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...
