An observer watching a fireworks display sees the light from the explosion and hears the sound 2 seconds later.How far was the explosion from the observer?
if speed o sound = V meters per second
then 2 V
be answered
To determine the distance of the explosion from the observer, we can use the fact that sound travels at a constant speed in air. The speed of sound in air is approximately 343 meters per second at room temperature.
Since the observer hears the sound 2 seconds after seeing the light, we can calculate the distance using the formula:
Distance = Speed × Time
In this case, the time is 2 seconds, and the speed is the speed of sound in air (343 meters/second).
Distance = 343 meters/second × 2 seconds
Distance = 686 meters
Therefore, the explosion was approximately 686 meters away from the observer.
