It is going away so you hear a longer wavelength
so LOWER frequency
An ambulance is going away from me @ 40mph with a siren @ 1000Hz.Will I heat a higher or lower frequency

Use this simplified equation, which is short and dirty method to determine the answer to your question:
f=v/c*(f')
Where
v=-40mph=-17.88m/s
c=3 x 10^8 m/s
f'=1,000Hz
Just eyeballing the numbers, you should see a lower frequency, since v is negative.
f=v/c*(f')
Where
v=-40mph=-17.88m/s
c=3 x 10^8 m/s
f'=1,000Hz
Just eyeballing the numbers, you should see a lower frequency, since v is negative.
I didn't know that you answered the question.
c=360m/s
I gave you the speed of light and not sound.
