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

Serjik [45]

Answer:

The Tuskegee Syphilis Experiment

Explanation:

The Tuskegee Syphilis Experiment was a social research that sought to find out the natural history of syphilis, with the purpose of justifying treatment programs for blacks.

Termed as “Tuskegee Study of Untreated Syphilis in the Negro Male.” It started in 1932, and lasted till 1972, when it was discovered that the reasearch was conducted without the benefit of patients’ informed consent.

Following a governmental review of the study, it was concluded that, the subjects involved in the research had been misled and had not been given all the facts required to provide informed consent, hence, the study was considered to be "ETHICALLY UNJUSTIFIED" that is, the knowledge acquired was minute when compared with the risks the study posed for its subjects.

Therefore, The Tuskegee Syphilis Experiment was an example of a major ethical mistake in the history of social research.
