If you drop a rock off a cliff and it takes you 3.2 seconds to hear it how high was the cliff the speed of sound is 340ms?

The sound moves in a second 340 metres. That is in 3.8 seconds 1292 metres. But because there is the way down to the ocean and back to the ears of the stone dropper, the distance must be half of it. The cliff is 646 meters high.

∙ 9y agoThe height is given by s=0.5x9.8xt1. The same height travels a distance s such that s=340xts. On solving the two equations with t1=3.2, we get s=46 m.

What is the velocity of sound at 30 degrees Celsius?
Speed of sound is c ≈ 331 + 0.6 × T T = temperature in °C. Speed of sound at 30°C is c ≈ 331 + 0.6 × 30 = 349 m/s.
How far will sound travel through air in 5 seconds?
That will depend on the speed of sound - which depends mainly on what material the sound travels through. For example, the speed of sound in air is about 350 meters/second.In any case, if you divide the distance (in meters) by the speed of sound (in meters/second) you will get the time (in seconds).
How far can a sound wave travel in water in 2.5 seconds if the water temperature is 25 degrees?
Speed of Sound in Water at 25ºC = 1533 m/s(Remember It)And Time = 2.5 sNow_Speed=Distance/TimeDisance=Speed*TimeD=1533*2.5D=3832.5 Metre
How does the speed of sound in steel compare with the speed of sound in air?
The speed of sound in steel is faster than the speed of sound in air.
Sound travels 344m in 1 second at this rate how far does sound travel in 8 seconds?
I think it must be 8 times as much. That is 2752 meters in 8 seconds.
What is the speed of thhe sound?
It is different in different conditions. Generally it has 340ms-1 as the speed.
What was the speed of sound in 1947?
It was the same speed. It generally travel with 340ms-1 speed.
A rock is dropped from a sea cliff and the sound of it striking the ocean is heard 3.8s later If the speed of sound is 340 ms how high is the cliff?
The sound moves in a second 340 metres. That is in 3.8 seconds 1292 metres. But because there is the way down to the ocean and back to the ears of the stone dropper, the distance must be half of it. The cliff is 646 metres high.
What is the speed of sound in air when the air has a temperature of 20degree celies?
That will not only depend on the temperature, but also on the exact composition of the air (such as, whether it is dry or humid), and possibly on the pressure. The typical speed of sound at 20 degrees C is approximately 343 meters/second.
How many meters will sound travel in 30 seconds?
The speed of sound at sea level is 10,208.7 meters per 30 seconds.
What is the velocity of sound at 30 degrees Celsius?
Speed of sound is c ≈ 331 + 0.6 × T T = temperature in °C. Speed of sound at 30°C is c ≈ 331 + 0.6 × 30 = 349 m/s.
What is the speed of sound in air at 42.0 C?
At 14 °C the speed of sound is 339.8 m/s. Here is an easy calculator to di that: http://www.sengpielaudio.com/calculator-speedsound.htm Cheers ebs
A ball is thrown horizontally from a cliff at a speed of 15 ms and strikes the ground 45 meters from the base of the cliff How long was the ball in the air?
Answer: 3 seconds
Suppose a rock is dropped off a cliff with an initial speed of 0 What is the rock's speed after 5 seconds in if it encounters no air resistance?
49
What is the property of sound which tells about its distance?
Its speed relative to the speed of light. (Roughly sound travels at one mile per 5 seconds.)
