Question
If you were 10 km away from a lightning strike, when would you hear the thunder?Question response areaSelect one option3.0 seconds later3.5 seconds later3.8 seconds later4.0 seconds later
Solution
The speed of sound in dry air at 20 degrees Celsius is approximately 343 meters per second. To find out when you would hear the thunder, you need to divide the distance by the speed of sound.
Step 1: Convert the distance from kilometers to meters. 10 kilometers is equal to 10,000 meters.
Step 2: Divide the distance by the speed of sound. 10,000 meters divided by 343 meters per second equals approximately 29.15 seconds.
Therefore, you would hear the thunder approximately 29.15 seconds after seeing the lightning strike. However, this is not one of the options given in your question. Please check the question again.
