The depth of a well can be determined by measuring the time of fall of a stone. How deep is the well if we hear the sound of the fall after 2.40 s? Note that the speed of sound in air is 340 m/s. How big is the relative error if ignore the travel time of sound?

A man drops a rock into a well. (a) The man hears the sound of the splash 2.40 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? (b) What If? If the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated?
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?
Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 3.74 seconds later. (A) If the speed of sound in air is 343 m/s at the rock climbers location, what is the depth of the chasm? (B) What is the percentage of error that would result from assuming the speed of sound is infinite?
Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 3.74 s later. (A) If the speed of sound in the air is 343 m/s at the rock climbers location, what is the depth of the chasm? (B) What is the percentage of error that would result from assuming the speed of sound is infinite ?
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?
A lightning bolt is observed and the resultant thunderclap is heard 5 seconds afterwards. Assuming the speed of sound in air is 340 m/s, how far away was the lightning bolt? Your answer should be in units of m but you should only submit the number for your answer.
A boy on a hill A fires a gun. The other boy on hill B hears the sound after 4 s. If the speed of sound is 330 m s-1, find the distance between the two hills.
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
Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 3.24s later. (a) If the speed of sound in air is 343 m/s at the rock climber's location, what is the depth of the chasm? 51.35 x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate res accuracy to minimize roundoff error, m (b) What is the percentage of error that would result from assuming the speed of sound is infinite? 0.175 from the henint arh sten carefully
A stone is dropped down a well with a velocity of 3.28 ft/s and 16.30 seconds later the sound of the splash is heard. If the velocity of sound is 1130 feet per seconds. What is the depth of the well?
Picnickers see a lightning flash and hear the resulting thunder 5 seconds later. The storm is traveling at a rate of 21 km/hr.Use 344 m/s for the speed of sound.(a) Roughly how far away is the storm in miles?Don't use this number for parts (b) thru (e)(b) How far away is the storm (hint: use 344 m/s...)?(c) How fast is the storm in m/s?(d) How long do the picnickers have before the storm arrives (sec)?(e) How long do the picnickers have before the storm arrives (min)?
Sound produced by a thunderstorm is heard 10 s after the lightning is seen. Calculate the approximate distance of the thunder cloud. (Given speed of sound = 340 m/s)
