You are on a boat in a fog and know there are cliffs ahead of you somewhere, but you cannot see them. You use your fog horn to send out a blast of sound (assume the temperature of the air is 20 oC) and the time it takes for the sound to return to you is 20.0 s. How far away are the cliffs (in metric units)? Hint: Be careful and think about the physics of the problem. You may want to make a sketch of the situation to help you determine the answer.

In Bosnia, the ultimate test of a young nuns courage used to be to jump off a 400-year-old bridge (destroyed in 1993; rebuilt in 2004) into the River Neretva, 23 m below the bridge. (a) How long did the jump last? (b) How fan was the jumper traveling upon impact with the river? (c) If the speed of sound in air is 340 m/s, how long after the jumper took off did a spectator on the bridge hear the splash?
You place your ear onto a steel railroad track and hear the sound of a distant train through the rails Δt = 3.3 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. 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. 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. Use the difference in these two times to write an equation for the distance to the train. For the given information find the distance to the train in meters
Question 25 In an experiment, two students measured the speed of sound in sea water at room temperature (20°C). Both of the students recorded their results in their notebooks as follows: A) (1515 + 7)m/s B) (1522 + 4) m/s The students then looked up the value for the speed of sound in sea water and found it to be 1531 m/s. Which of the following statements best describes the comparison between the students' results and the accepted value for the speed? The values that the two students found did not agree with each other, but one of the student's answer did agree with the accepted value. The values that the two students found agree with each other but not with the accepted value. The values that the two students found did not agree with each other, nor with the accepted value. The values that the two students found agree with each other and with the accepted value. The values that the two students found were wrong and should have agreed with the accepted value.
On December 26, 2004, a great earthquake occurred off the coast of Sumatra and trig- gered immense waves (tsunami) that killed some 200, 000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1.0 hour. What was the speed of these waves in m/s and km/h? Does your answer help you understand why the waves caused such devastation?
Question 2 If the speed of sound in air at 0 °C is 331 m/s. What will be the speed of sound in air at 50 °C? 299 m/s 142 m/s 331 m/s 360 m/s None of these. A Moving to another question will ave this response. ch 45

There is a rule of thumb for estimating how far away a thunderstorm is. After you see a flash of lighting, count off the seconds until the thunder is heard. Divide the number of seconds by five. The result gives the approximate distance (in miles) to the thunderstorm. Why does this rule work? Vlight ✓sound 1.0 mile (1.6 x 10³ m)
Hullo! Physics student here! I'm struggling to figure out how to go about answering this question ): In one study of an adult bat, with a mass of 3.3 g and a wingspan of 111 mm, scientists found that this bat emitted a high-pitched sound that travelled 25.5 m in 78.7 ms. Calculate the speed of sound (in m/s) in this situation. Hint: Enter only the numerical part of your answer rounded to the nearest integer.
Radio waves are electromagnetic waves that travel at a speed of 3.00 x 10^8 m/s, the speed of light. An AM radio station has an assigned frequency of 601 kHz, which means that the radio waves broadcast by the station are at this frequency. Find the wavelength of these radio waves. PLEASE ANSWER WITH CORRECT NUMBER OF SIGNIFICANT FIGURES. The answer is not 5x10^2
The air temperature was 77.0°F during a thunderstorm, and thunder was timed 5.20 s after lightning was seen. How many feet away was the lightning strike?

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.
