Question

Раскаты грома были услышаны через 8с после вспышки молнии . На какой удалённости от наблюдателя ударила молния (скорость распространения звука в воздухе равна 340м/с) .

Answer 1

S=V*t=340*8=2720 м

Answer 2

Calculation of Lightning Distance

To calculate the distance of the lightning strike from the observer, we can use the speed of sound in air, which is approximately 340 meters per second Since the sound of thunder is heard after a certain delay from the lightning flash, we can use this delay to estimate the distance.

In this case, the thunder was heard 8 seconds after the lightning flash. To determine the distance, we can multiply the speed of sound by the time delay:

Distance = Speed of Sound × Time Delay

Distance = 340 m/s × 8 s

Distance = 2720 meters

Therefore, the lightning strike occurred at a distance of approximately 2720 meters from the observer.
