Answer:

The sound of the horn will sound louder as the car approaches.

Explanation:

The name “Doppler Effect” is a reference to Austrian physicist Christian Johann Doppler, who studied and described it. This scientist wrote an article in which he states that the frequency of sound perceived by an observer depends on the relative movement between the emitting source of sound and the observer.

A typical example of the Doppler effect is a car horn when approaching or moving away from an observer. As she approaches the observer, the sound is louder; and when the car pulls away, the sound is louder. This is a characteristic phenomenon of any wave propagation, and it is much more present in everyday life than we think.

A phylogenetic tree based on morphology can be constructed using the presence or lack of characteristics. In this illustration, all aliens except the outgroup possess a spring tail, all aliens possess a fourth eye, two aliens possess two tails, and one alien has a grasping hand. The evolutionary relationships between these organisms can be hypothesized using these traits.

Aliens:

  • We can determine whether the following traits are present in the remaining aliens by using the group of aliens with the tail stalk as our test group.
  • Out group: a group that is maintained apart from the clade but is yet connected to it.
  • If we provide these aliens alphabets for ease of understanding, then aliens will be like in order.
  • We can use the group of aliens with the tail stalk as our test group to see if the following characteristics are present in the remaining aliens.
  • A group that is kept separate from the clade while yet being affiliated with it is known as an out group.
  • The aliens will appear to be in order if we give them alphabets for simplicity.
