4) Coyote once again is fooled by Roadrunner and has inadvertently run off a tall cliff. Realizing his predicament, he lets out a scream as he falls all the way to the bottom. From the vantage point of Roadrunner still at the top of the cliff leaning over the edge, the pitch of Coyote's scream as he falls is: A) higher than the original pitch and constant. B) higher than the original pitch and increasing as he falls. C) lower than the original pitch and constant. D) lower than the original pitch and decreasing as he falls. E) It is impossible to predict.

#### Problem Statement:
Coyote once again is fooled by Roadrunner and has inadvertently run off a tall cliff. Realizing his predicament, he lets out a scream as he falls all the way to the bottom. From the vantage point of Roadrunner still at the top of the cliff leaning over the edge, the pitch of Coyote’s scream as he falls is:
A) higher than the original pitch and constant.
B) higher than the original pitch and increasing as he falls.
C) lower than the original pitch and constant.
D) lower than the original pitch and decreasing as he falls.
E) It is impossible to predict.
#### Explanation:
The scenario presented is a classic example of the **Doppler Effect**, which describes the change in frequency (or pitch) of a sound wave in relation to an observer who is moving relative to the source of the sound. In this case, Coyote is the source of the sound (his scream), and Roadrunner is the observer.
As Coyote falls away from Roadrunner, the distance between the source of the sound (Coyote) and the observer (Roadrunner) increases. This increase in distance causes the sound waves to stretch out, resulting in a lower frequency or pitch heard by Roadrunner.
#### Analysis:
- If the pitch were higher and constant, it would imply that Coyote is moving toward Roadrunner at a constant rate, which contradicts the scenario.
- If the pitch were higher and increasing, it would suggest an increasing rate of movement towards Roadrunner, also not applicable here.
- If the pitch were lower and constant, it might imply uniformity, but a constant fall would still make the pitch progressively lower due to increasing distance.
- The most accurate description given the Doppler Effect and the increasing distance is:
- **D) Lower than the original pitch and decreasing as he falls.**
Hence, the correct understanding of the Doppler Effect applied to this situation results in the conclusion that the pitch of Coyote’s scream, as heard by Roadrunner, is lower than the original pitch and continues to decrease as Coyote falls further away.
