9. The time between a lightning flash and the following thunderclap may be
used to estimate, in kilometers, how far away a storm is. How far away is
a storm if 6 second elapse between the lightning and the thunder clap?
Use the formula d = t/3 , in seconds, between the flash and the
thunderclap.
o 18 kilometers
+ 2 kilometers
o 3 kilometers
o 9 kilometers
Is it b, 2 kilometers?
Well, assume the velocity of light, about 3 * 10^8 meters/second is so high that the flash reaches you instantly.
V of sound in air is about 343 meters/second
distance = speed * time
= 343 * 6 = 2058 meters = 2.058 kilometers
or using their formula 6/3 = 2
yes
Yes, the correct answer is 2 kilometers.
To calculate how far away a storm is based on the time between a lightning flash and the following thunderclap, we can use the formula d = t/3, where d is the distance in kilometers and t is the time in seconds.
Given that 6 seconds elapse between the lightning and the thunderclap, we can substitute t = 6 into the formula:
d = 6/3
d = 2 kilometers
Therefore, the storm is approximately 2 kilometers away.
