A person hears a thunder 3 seconds after a flash of lightning is seen. At what distance has the lightning struck? (velocity of sound in air = 340 m/s). pls give answer
Answers
Answer:
Lightning and thunder are produced simultaneously, but the thunder is heard a few seconds after the lightning is seen. This is because the speed of light in air is more than the speed of sound in air. The speed of sound is 340 m/s.Thus, the entire time of 4 seconds (as mentioned in the question) between seeing the light and hearing the thunderstorm is taken by the sound to travel to the observer. Hence, the distance traveled by the thunder is given as follows.s=vt; where,s is the distance traveled, v is the velocity of sound and t is the time taken. That is, 340 * 3s = 1360 m.please mark me as brainlists
Answer:
Explanation:
time taken=3
velocity=2*distance/time [this given 3s represent the time taken by the flash to go to the destination and come back and hence twice the distance has to be considered]
340=2*distance/3=distance=510m
