If you know the speed of sound in air at 20°C is 343 m/s, calculate the expected speed at 0°C using the formula v = 331 + 0.6 × T.
💡 Hint: What is the formula we discussed?
A stationary observer notes the frequency of a siren from an approaching ambulance to be 600 Hz. If the ambulance moves towards the observer at a speed of 30 m/s, what is the perceived frequency?
💡 Hint: Think of the speed of sound and how motion alters frequency perception.
