Question

-. During a thunderstorm,
Yogesh sees a blinding flash
of lightning and hears the
crack of thunder after 3 s. If
sound travels at 1206 km/h,
how far from Yogesh did the
lightning occur?​

Answer 1

Answer:

gThunder is a result of the rapid expansion of super heated air caused by the extremely high temperature of lightning. As the lightning bolt passes through the air, the air expands faster than the speed of sound generating a "sonic boom". Since the sonic boom is created along the path of the lightning bolt, in effect, millions of sonic booms are created, which we hear as a rumble.  

Thunder from a nearby lightning strike will have a very sharp crack or loud bang, whereas thunder from a distant strike will have a continuous rumble. The primary reason for this is that the sound shock wave modifies as it passes through the atmosphere.  

Sound travels roughly 750 mph (1200 kph), or approximately one mile every 5 seconds (one kilometer every 3 seconds). The speed actually varies greatly with the temperature, but the thumb rule of 5 seconds per mile is a good approximation.

Answer 2

Answer:

201m

Step-by-step explanation:

First convert 1206km/hr in m/s by multiplying by 5/18.

you will get 67m/s.

then apply this formula -

distance = speed x time

distance = 67 x 3

distance = 201

Final Answer: 201 m
