a stone is dropped into a well 44 meter deep and the sound of speash is heared after 3.12 second find the speed of sound air
Not given answer Pagal
To find the speed of sound in air, we can use the formula:
Speed = Distance / Time
In this case, the distance the sound wave travels is the depth of the well, which is 44 meters. The time it takes for the sound of the splash to be heard is given as 3.12 seconds.
Therefore, we can calculate the speed of sound in air as:
Speed = 44 meters / 3.12 seconds
Speed ≈ 14.1 meters per second
Hence, the speed of sound in air is approximately 14.1 meters per second.
Time to reach bottom = t s
distance
44 m= (1/2)gt^2
where
g=acceleration due to gravity = 9.8 m/s²
=>
t=sqrt(2*44/g)=2.997 s
Subtract this time from 3.12 seconds will be the time needed for sound to travel 44 m.
Use
Distance=speed × time
to find speed of sound.
