Here ,
speeed of sound , v = 343 m/s
time taken = 4 s
distance of nearest wall = speed of sound * time/2
distance of nearest wall = 343 * 4/2
distance of nearest wall = 686 m
the distance of nearest wall is 686 m
You are lost in a canyon and yell for help. Four seconds later you hear your...
Standing in a canyon, you yell "Physics is awesome" and hear the echo 5 seconds later. How far did the wave travel?
You are hiking along a trail in a wide, dry canyon where the
outdoor temperature is T = 27° C. To determine how far you
are away from the canyon wall you yell “Hello” and hear the echo
t = 2.75 s later.
33% Part (a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0° C is 332 m/s. v = 348.2 Correct! A33% Part (b) How far are you from the...
On a hiking trip, you are walking through a canyon with vertical walls and are closer to one wall than the other. Having taken Physics, you decide to determine the width of the canyon by using your knowledge of kinematics and the speed of sound. You shout "Hey" as loud as you can, and after a short time you hear three echoes. The second echo arrives 1.5 safter the first, and the third echo arrives 0.9 s after the second....
When you drop a rock into a well, you hear the splash 2.0 seconds later. How deep is the well? If the depth of the well were doubled, would the time required to hear the splash be greater than, less than, or equal to 4.0 seconds? Please explain why
Suppose that during a thunder-storm you hear a clap of thunder 6.06 seconds after you see a lightning strike. How far away are you from the lightning strike? Assume room temperature air. Assume light travels so fast that you see the lightning nearly instantaneously.
You drop a rock into a deep well and 4.6 s later hear the splash. How far down is the water? Neglect the travel time of the sound. Express your answer using two significant figures.
Please show all work for this exercise
At 20°C, a student sets off a firecracker and hears the echo from the Physics building 1.4 seconds later. How far away is the Physics building in meters?
. At your apartment, you hear the busy road (the dB level of a freeway is 80 dB from 1.00 m away) and measure the noise at a constant level of 45 dB. a) What is the power output of traffic on the road? b) How far away is your house from the road? c) How far from the road would you need to be for the sound to measure at 20 dB? d) Town Hall is planning to add...
At your house, you hear the busy freeway (the dB level of a freeway is 80 dB from 1.00 m away) and measure the noise at a constant level of 45 dB. A. What is the power output of traffic on the freeway? B. How far away is your house from the freeway? C. How far from the freeway would you need to be for the sound to measure at 20 dB? D. Town Hall is planning to add panels...
You are watching a lightning storm through your window. You see a big flash of light and you start counting the seconds: one potato, two potatoes, three potatoes... You hear loud thunder when you are at 13 in your counting. If sound travels one kilometer in three seconds, then how far is the storm from you? You can get a pretty good approximation of the distance in miles, if you assume that sound travels one mile in five seconds. What...
