The speed of sound in air at sea level is 340m/s while that of light is 300,000km/s. how far ( to the nearest metre) from the centre of the thunderstorm is an observer who hears a thunder 2s after the lightning?
d = V * t = 340 * 2 = 680 m.
Yes

To determine the distance from the observer to the center of the thunderstorm, we need to calculate the time it took for the sound to reach the observer.
Given:
Speed of sound in air: 340 m/s
Time between lightning and thunder: 2 seconds
We know that the speed of sound is the distance traveled per unit time. So, we can calculate the distance traveled by sound using the formula:
Distance = Speed × Time
Distance = 340 m/s × 2 s
Distance = 680 m
Therefore, the observer is approximately 680 meters away from the center of the thunderstorm.
