Question

5- During the Canada Day fireworks demonstration, an observer measures the time difference between the

flash of light emitted, and the sound heard from the explosion to be 2.50 s. If the air temperature is 16°C.
how far away is the fireworks' explosion from the observer? (Velocity of sound is 345 m/s at 0 °C)

Answer 1

Below

Step-by-step explanation:

Speed of sound at 16 degrees C = 340.866 m/s

(Speed of sound at 0 degrees C is 331.3 m/s ....I do not know where they got the incorrect value of 345 m/s at 0 °C)

2.5 s * 340.866 m/s = 852 m away from fireworks
