Answer :
Final answer:
The speed of sound in air at 66 degrees Celsius is approximately 371.8 meters per second using the formula v = 331.4 + 0.6T.
Explanation:
The speed of sound in air is given by the equation v = 331.4 + 0.6T where v is the speed of sound and T is the temperature in degrees Celsius. So if we substitute 66 for T in the equation, we get:
v = 331.4 + 0.6 * 66 = 371.8 m/s.
This calculation shows that the speed of sound in air at 66 degrees Celsius is approximately 371.8 meters per second.
