If a storm is 7.5 kilometers away, how much time is expected between observations of lightning and thunder? Round your answer to

Svetlanka [38]

Answer:

22.5 s is the correct answer to the given question .

Explanation:

Given that

$d=7.5km=7.5\times 10^3 m$

For light:

We know that speed of light c

$c=3\times 10^8 m/s$

We know that

$Distance = Speed \times timed=C\time tt=\dfrac{D}{t}t=\dfrac{7.5\times 10^3}{3\times 10^8}\ st=2.5\times 10^{-5}st=0.025 ms$

For thunder :

Speed of sound ,v=332 m/s

$Time\ taken\ by\ sound \\t\’=\dfrac{7500}{332}=22.59 s$

Therefore the difference between time is given as follows

$\Delta t= t' - \ t=22.59-2.5\times 10^{-5}=22.59 s$

22.5 is the answer
