Question
CBSEENSC9006580

During a thunder storm, sound is heard 10 s after the lightning is seen. What is the distance of the cloud from the observer ? Take velocity of sound as 330 m/s.

Solution

Given,

time lapse between thinder and lightning, t = 10 s

Velocity of sound, v = 330 m/s

So, distance travelled, s = vt 

                                    = 330 x 10

                                    =  3300 m
