Question

On a rainly day thunder of sound is heard 2 second after seeing the lightning what is the nearest position of lightning? Take speed sound in air =346ms-1

Answer 1

The Lightning was 692 metres away this is because sound from the lightning took 2 minutes to come to the receiver. As distance = speed × time so the distance from lightning = 2 X 346 which equal 692 metres

Answer 2

Answer:

692 m

Explanation:

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 = 2 seconds

To find: Distance between Nita and that Lightning

So,

Velocity = Distance / Time

340 m/s = Distance / 2 seconds

Distance = Velocity * Time

Distance = 346 * 2

Distance = 692 meters

Therefore, the distance of Lightning from Nita is 692 meters.
