The correct answer is B. Aggregate
Explanation:
The meeting and interaction of two or more people are frequently called a social group. However, there are different types of groups depending on the way the people that are part of the group interact and are organized. In the case of aggregate individuals or collection, there is no cohesion, interaction or sense of unity between the individuals that are gathered. This means an aggregate is just different individuals that gather at the same and place but who do not interact or think about the others as a group, for example, the people waiting for a bus in a bus stop are considered as aggregate. This type of group is different from primary or secondary social groups as there is not any type of relationship, common goal or shared features between different people. Thus, if people gather in the same place at the same time but lack organization or lasting patterns of interaction they form an aggregate.
Answer:
Doppler Effect
Explanation:
Doppler Effect is a term in Physics that describes the phenomenon experienced when there is change in wave frequency during the relative motion between a wave source and its observer.
In other words, it is referred to as increase or decrease in the level of sound, or other waves as the distance between source and observer is closer or farther from each other, such that it causes change in pitch, which is noticeable by the observer.
For example, when a sound object moves towards an individual or observer, the frequency of the sound waves increases, leading to a higher pitch, and at the same time, when the sound object moves away from an individual or observer, the frequency of the sound waves decreases, leading to a lower pitch. E.g passing siren from ambulance.
Hence, in this case, the right answer is DOPPLER EFFECT
