A fired bullet sounds is heard after2sec .its speed in air is 340m\sec.what is the distance of sound.
340m/s * 2s = 680m
To determine the distance of the sound, we need to consider the time it takes for sound to travel in air. The speed of sound in air is approximately 343 meters per second at room temperature.
Given that the sound of the fired bullet is heard after 2 seconds, we can calculate the distance of the sound using the formula:
Distance = Speed × Time
Substituting the values:
Distance = 343 m/s × 2 s = 686 meters
Therefore, the distance of the sound of the fired bullet is 686 meters.
