Out in the sea, ship A and ship B can hear the loud noise the horn's make in the distant lighthouse. It takes 30 seconds for ship A to hear to horn and 40 seconds for ship B to hear the same horn. Given that the two ships make an angle of 43∘ with the lighthouse, what is the straight line distance between the two ships and that the speed of sound in air is 330 m\s? Construct a triangle first in your answer to easily view the problem.

The highest frequency that we can hear is about 20 kHz (2x 10^4Hz). a) Calculate the wavelength (m) associated with this frequency for sound that travels at 345 m/s. b) How long is this in feet? (Roundanswers to the nearest tenth.
You place your ear onto a steel railroad track and hear the sound of a distant train through the rails Δt = 2.7 seconds before you do through the air. The speed of sound in steel is vs = 6100 m/s, and and the air temperature is 36° C. Find the distance, D, to the train in meters.
What is wrong with the following expressions? How can you correct them?
You place your ear onto a steel railroad track and hear the sound of a distant train through the rails Δt = 3.6 seconds faster than you do through the air. The speed of sound in steel is vs = 6100 m/s while in air the speed of sound is va = 343 m/s. (a) Write an equation for the time it takes the sound to reach you through the air if the distance to the train is represented by D. (b) Write an equation for the time it takes the sound to reach you through the steel if the distance to the train is represented by D. (c) Use the difference in these two times to write an equation for the distance to the train. (d) For the given information find the distance to the train in meters.
A ship sends a signal out to determine the depth of the ocean. The signal returns 2.5seconds later. If sound travels at 1450 m.s−1 in sea water, how deep is the ocean at that point? Convert your answer into kilometers.
A screwdriver is dropped from the top of an elevator shaft. Exactly 5.0 seconds later, the sound of the screwdriver hitting bottom is heard. How deep is the shaft? The shaft is approximately (Round to the nearest tenth.) feet deep. Hint: The distance that a dropped object falls in t seconds is represented by the formula s = 16t². The speed of sound is 1100 ft/sec.
On December 26, 2004, a great earthquake occurredoff the coast of Sumatra and triggered immense waves (tsunami) thatkilled more than 200,000 people.

Consider an omnidirectional mobile robot with a ring of twelve ultrasonic sensors (each with an opening angle of 30o) that are fired sequentially. Calculate the slowest scan rate in Hz (i.e. number of full 360o scans per second) if the furthest object of interest is 4m away at any given time. Give your answer to 2 decimal places. Assume the speed of sound in air is 343 m/s.
