<u>Alpha radiation</u> is a type of airborne particle that rapidly loses energy as it moves through the atmosphere, has weak penetrating strength, and can be prevented by clothing or a piece of paper.
<h3><u>Why does alpha radiation exist?</u></h3>
Two protons and two neutrons are bonded together to form an object resembling a helium-4 nucleus, which is what is known as an alpha particle, also known as an alpha ray, or alpha radiation. Although there are additional possibilities, they are often created during the alpha decay process.
The Greek letter, which begins the alphabet, is where the name "alpha particle" originates. Alpha is represented by the sign 2+. Net spin is zero for alpha particles. Alpha particles typically have a kinetic energy of around 5 MeV and a velocity in the area of 4% of the speed of light because of the mechanism of their generation in ordinary alpha radioactive decay.

Pythagoras could be argued as one of the most influential scientists of his time. Pythagoras worked to discover many mathematical and scientific discoveries, including the Pythagorean theorem, Pythagorean tuning, the five regular solids, the Theory of Proportions, the sphericity of the Earth, and the identity of the morning and evening stars as the planet Venus.
C. Israel
Religion in Israel is a central feature of the country and plays a major role in shaping Israeli culture and lifestyle, and religion has played a central role in Israel's history. Israel is also the only country in the world where a majority of citizens are Jewish.
In the early 1960s, sociologist Herbert Gans moved into a newly developed suburb in new jersey where he lived for two years, observing and interviewing his neighbors. in research terms, Gans conducted a participant observation study. Participant observation is method used for data collection, in which the <span>the </span>observer is a "player" in the action (he/she <span>participates in ongoing activities and records </span>observations). The technique is used in many studies in Anthropology and Sociology.
Answer:
Correct option is (D)
Explanation:
Qualitative research is carried out by the researcher to understand a phenomena without using quantitative techniques. The variables are not quantified.Though, it can act as a boundary study from quantitative research.
A qualitative research requires the research instruments to be objective and objectivity of researcher. It measures social and emotional responses in the form of people's experiences, opinions and beliefs. It however, does not require use of mathematical or statistical techniques to make inferences or conclusions.
