Question

Ramesh measured the time gap between lightning and thunder and found that it was 3 second assuming light cover the distance instantly what is the distance of the clouds from Ramesh

Answer 1

Given:
speed of sound in air=approximately 340m/s[it varies according to atmospheric density and moisture amount]
t=3 sec
speed=distance/time
distance = speed x time
=340x 3=1020m
So the distance of the clouds from ramesh is 1020m

Answer 2

Answer:

Given:

speed of sound in air=approximately 340m/s[it varies according to atmospheric density and moisture amount]

time gap= 3 seconds

speed=distance [distance/time]

time

distance=speed × time

=> distance=340×3m

=>distance of clouds from Ramesh=1020m or 1km 20m
