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.
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
