Question

Реактивный самолёт за 2 сек пролетел 8 км а звук за 4 сек распространился на 1320 метров сравните скорость самолёта и звука срочно дам 50 баллов

Answer 1

Скорость самолета V1=S1/t1=8000/2=4000 м/с
Скорость звука V2=S2/t2=1320/4=330 м/с
V1/V2=4000/330=12,1
V1>V2 в 12,1 раза.

Answer 2

Calculation of Speed

To compare the speed of the airplane and the speed of sound, we can use the formula:

Speed = Distance / Time

Given that the airplane traveled 8 km in 2 seconds, we can calculate its speed as follows:

Airplane Speed = 8 km / 2 s = 4 km/s Similarly, we can calculate the speed of sound by dividing the distance it traveled (1320 meters) by the time it took (4 seconds):

Speed of Sound = 1320 m / 4 s = 330 m/s

Comparison of Speeds

Now that we have calculated the speeds, we can compare them:

- The speed of the airplane is 4 km/s. - The speed of sound is 330 m/s.

As we can see, the speed of the airplane is significantly higher than the speed of sound. The airplane is traveling at a much faster rate compared to the propagation of sound waves.

Please note that the speed of sound can vary depending on various factors such as temperature, humidity, and altitude. The value of 330 m/s is an average value at sea level and room temperature.
