Answer:
The detect frequency is 1622.72 Hz.
Explanation:
Given that,
Frequency = 1500 Hz
Suppose you move with a speed of 27.0 m/s toward the fire engine. what frequency do you detect ?
We need to calculate the frequency
Using formula of frequency
[tex]f=(\dfrac{v+v_{0}}{v})f_{0}[/tex]
Where, v = speed of sound
v₀ = speed of source
f₀ = frequency of siren
Put the value into the formula
[tex]f=\dfrac{330+27.0}{330}\times1500[/tex]
[tex]f=1622.72\ Hz[/tex]
Hence, The detect frequency is 1622.72 Hz.
