Question

J. Find the distance of cloud from you when you hear a thunder 3 sec after the
lightning is seen. (given the speed of light=3*10% m/s, speed of sound=
330m/s)? Why is lightning seen a few seconds before the thunder is heard
during a thunderstorm?

Answer 1

Answer:

$speed = \frac{distance}{time}$

hence

$330 = \frac{x}{3}$

hence x is 330*3=990

the distance is 990 m

you see lightning before hearing it because speed of light is greater than that of sound
