Question

A sound is heard 5s later than the lightning in seen in the sky on a rainy day . find the distance of location of lightning? Given the speed of sound .346ms-1

Answer 1

This is not echo.

This is direct sound

The distance of thunder storm = Speed of sound X time

                                                   = 0.346 X 5

                                                   = 1.73 Km

Answer 2

Answer:

1730 meters

Explanation:

Let someone is Nita:

Suppose Nita is stood in open ground and she heard the lightning sound after 2 seconds of seeing it.

Given that,

Velocity of sound in air = 346 m/s

Time required = 5 seconds

To find: Distance between Nita and that Lightning

So,

Velocity = Distance / Time

346 m/s = Distance / 5 seconds

Distance = Velocity * Time

Distance = 346 * 5

Distance = 1730 meters

Therefore, the distance of Lightning from Nita is 1730 meters.
