V. сорд 20 V₁ car VcopB ▾ Part A. Case 1: Cop car A emits the radar signal (of frequency 1,) which is heard by the driver in the red car (at a frequency 1). What is the frequency difference Aff-f, with a proper sign? Round to an integer. Critical Note: If you calculate the frequency of the radar signal detected by the driver in the red car before calculating the differoo, you must keep 10 digits in order to see the difference between the original emitted frequency and this received frequency. Case 1 Af- -1462 Hz Submit Previous Answers All attempts used; correct answer displayed Two cop cars A and B both use radar unit of a frequency of -8.8x10 Ha.
