Question

Наблюдатель,находящийся в 4 км от артиллерийского орудия,услышал звук выстрела через 12 с после вспышки.По этим данным определите скорость звука в воздухе

Answer 1

Звук "движется" равномерно

 

Из этого имеем

 

v=s/t=4/12=0.3 км/ч

Answer 2

Дано

S=4км=4000м

t=12c

V-?

V=S/t,  V=4000/12=333,3м/с- скорость звука в воздухе

Answer 3

Calculation of the Speed of Sound

To determine the speed of sound in the air, we can use the given information about the observer's distance from the artillery gun and the time difference between the flash and the sound of the gunshot.

Let's break down the problem:

- The observer is located 4 km away from the artillery gun. - The time difference between the flash and the sound of the gunshot is 12 seconds.

To calculate the speed of sound, we can use the formula:

Speed of Sound = Distance / Time

In this case, the distance is 4 km (or 4000 meters) and the time is 12 seconds.

Plugging in the values, we get:

Speed of Sound = 4000 meters / 12 seconds

Now, let's calculate the speed of sound:

Speed of Sound = 333.33 meters per second

Therefore, the speed of sound in the air, based on the given information, is approximately 333.33 meters per second.

Please note that this calculation assumes standard atmospheric conditions and may vary depending on factors such as temperature, humidity, and altitude.
