b. a decrease in the frequency of the sound wave.
c. an increase in the frequency of the sound wave.
d. an increase in the amplitude of the sound wave.
b. a pitch lower than the original pitch.
c. an amplitude lower than the original amplitude.
d. a frequency higher than the original frequenc
Correct answer choice is:
D. A frequency higher than the original frequency.
Explanation:
This is a true case of Doppler's effect. The Doppler effect can be defined as the effect originated by a traveling source of waves in which there is a visible higher variation in pulse for observers towards what the source is progressing and a visible descending shift in rate for observers from what the source is dropping.

Answer:
23.5 N
Explanation:
Just wanted to clarify something about the verified answer: Our only given measurement—the mass of the object—has 3 significant digits, so we can only include 3 significant digits in our answer.
23.52 N is NOT the correct answer. Your answer should only have 3 significant digits.
I just did the quiz where this problem came from, so I know that 23.5 N is the correct answer.
Answer:
Valence electrons
Explanation:
The valence electrons are found in the outermost shell of an atom. They are the most loosely held electrons found within an atom. These valence electrons are involved and are used to form bonds when atoms combines together.
The energy required to remove these loosely held electrons is relatively low compared to electrons located in the inner orbitals. This is why when atoms combines, they use the outermost electrons to form bonds and mimic stable atoms like those of the noble gases.
B. original horizontality
C. uniformitarianism
D. faunal succession
