Question
Th e weather forecaster says the high temperature todayis going to be 18 °C. What will the speed of sound bewhen the temperature reaches the day’s high?
Solution
The speed of sound in air can be calculated using the formula:
v = 331.4 + 0.6T
where: v is the speed of sound in meters per second T is the temperature in degrees Celsius
Step 1: Substitute the given temperature into the formula. In this case, T = 18 °C.
v = 331.4 + 0.6 * 18
Step 2: Perform the multiplication.
v = 331.4 + 10.8
Step 3: Perform the addition.
v = 342.2 m/s
So, when the temperature reaches the day's high of 18 °C, the speed of sound will be 342.2 meters per second.
