a tour boat in a norwegian fjord approaches a shoreline, which is an essentially a vertical cliff. the boats whistle is sounded with frequency of f=100 hz and the passengers on the boat hear the echo frequency of 116 hz. the student from phys260 lays a wager that she can find the speed of the boat from this information. can you do it?? if so, not only you will win your wager, but also get a good grade on this test. ( take the speed of sound to be 330 m/s)
A Hunter is standing on flat ground between two vertical cliffs that are directly opposite one cliff than to the other. He fires a gun and, after a while, hears three echoes. The second echo arrives 1.8 s after the first, and the third echo arrives 1 s after the second. Assuming that the speed of sound is 343 m/s and that there are no reflections of sound from the ground, find the distance between the cliffs.
At 0C, the speed of sound is 330m/s. Knowing this, how far away are you if you hear a train whistle 10 minutes after it is blown?
