Question

please help me with all parts of this, make sure to double check your answer, i got it wrong, but i want to use this to study.

## Problem 16.61 **Scenario:** The predominant frequency of a certain fire truck's siren is 1350 Hz when at rest. ### Part A **Question:** What frequency do you detect if you move with a speed of 40.0 m/s toward the fire truck? - **Instructions:** Express your answer with the appropriate units. - **Input Box:** `f = 158.434403 Hz` - **Submission Status:** Incorrect; Try Again; 4 attempts remaining ### Part B **Question:** What frequency do you detect if you move with a speed of 40.0 m/s away from it? - **Instructions:** Express your answer with the appropriate units. --- **Note:** The problem involves calculating the apparent frequency of a sound when there is relative motion between the source and the observer, a classic application of the Doppler effect.
