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
Answer:
From the later months of age 2 and into the middle of their third year, the number of ways children combine words and phrases to form sentences grows each month.
Explanation:
As far as vocabulary is concerned, child develops an understanding to cover 100 words at just 18 months of age. Then comes the stage where the child begins to compose expressions and come to a basic understanding of syntax, the phase of telegraphic speech, and by the age of three, child has tripled vocabulary and doses of up to 1000 words (Sternberg 2005). Furthermore, from the second to the third year, the child understands the differences in the meaning of the word, names the word for all things and concepts, often looks for objects to name them, and speech is understandable to most listeners. In the 2nd year, the speech consists of nouns and verbs that child has created only (bi-bi, am-am, wow-wow) and those adopted from adults (dad, mom, car, juice). In the second half of the second year of life, the child begins to associate words and create the first sentences.

Explanation:
The belief that there is an empirical reality, but that our understanding of it is limited by its complexity and by the biases and limitations of researchers is called Postpositivism. Basic science is the effort to figure out what the world is like and why it works as it does.

Line, Region, Magnet, and Filter</span><span>.<span> . . Belonging truly to neither nation, it serves as a kind of cultural buffer zone for both, cultivating its own culture and traditions. Like other borders, it both attracts and repels. Like them, it is both barrier and filter. It is above all a stimulating cultural environment. . . .</span>--James S. Griffith
The Arizona Sonora border was established as a result of the Gadsden Purchase of 1853. It runs through desert and mountain country, from the western Chihuahuan Desert by New Mexico through a zone of grassland and oak-covered hills to the classic Sonoran Desert west of Nogales. The land gets more and more arid as one travels west, and the western third of the border is essentially devoid of human habitation. It is this stretch of the border, once a major road to the Colorado River, that has earned and kept the title El Camino del Diablo, "The Devil's Highway."</span>
