If a thunder clap is heard 5.5 s later than the lighting flash observed from the earth, then the distance of the flash will be
(Velocity of sound in air 330 m/s)

A

780 m

B

3560 m

C

1815 m

D

300 m

Text Solution

Verified by Experts

The correct Answer is:
C
`v = (d)/(t) " " : d = vt = 330 xx 5.5`
`= 330 (5 + (1)/(2)) = 330 xx 5 + (330)/(2)`
`= 1650 + 165`
`d = 1815
