Answer:
The correct answer is:
a. is a process consisting of multiple events, with a blurry line between life and death.
Explanation:
Biological death is declare in the medical field when the main activities of the body stop working, such as heart-beating, breathing, eyelid response to light, natural body warm decrease. It is possible to say that, there is normally a blurry line between life and death since other functions can last for a while more, after the biological death is declared.
I would say C bc of the key word “producing”
The sound wave produces a vibrating object. In this case, the vibrating string strings put the surrounding air molecules into vibrational motion. The frequency at which vibrates air molecules is equal to the frequency of the guitar strings. Vibrations of air molecules are temporary, and after a while, they return to their original position. Vibrations of air molecules create a wave of pressure that travels outside its source. This pressure creates compressions and rarefactions. Due to this pressure, the air molecules compress in a small space. Replacing compression and rarefactons is actually a sound wave. In this sense, the sound wave transfers energy from one place to another without the transport of matter. By increasing the frequency of the strings, the frequency of the vibrating air molecules increases and a louder sound is obtained.
The guitar string does not produce a high frequency by itself, and therefore the surrounding air molecules very little vibrate and produce a sound that is not loud. When the strings are attached to the acoustic guitar box, which is made of wood, then the guitar wood begins vibrating with the same frequency as the strings. Due to the large surface of the wooden guitar box, which vibrates with the same frequency as the strings, the box starts to mobilize a much larger number of air molecules to vibrate, thereby gaining a louder sound.
<u>Social </u>gerontology is the study of the nonphysical aspects of aging, including such topics as the societal consequences of an aging population and the personal experience of aging.
Gerontology is the study of ageing and how it affects people at all stages of life. The analysis of societal changes brought on by our ageing population; the study of physical, mental, and social changes in ageing individuals; and the application of this information to policies and programmes are all included.
Gerontology's subdiscipline of social gerontology is thought to be science-based but application-focused. The protection of their unique requirements and the preservation of their social interactions in old age are its main points of emphasis. Autonomy and self-determination are significant value orientations.
As the population ages, the older people's demands change, and as society adapts to meet these requirements, social gerontology will play a significant role in society. Gerontology's main objectives—to increase our understanding of ageing and use research to better the lives of older people—are supported by age-related research.
