Answer:
developmental scale, also called a vertical scale, allows the comparison of student academic progress over time in a particular subject by linking assessments at adjacent grades together.
The scale development process is critical to building knowledge in human and social sciences. The present paper aimed (a) to provide a systematic review of the published literature regarding current practices of the scale development process, (b) to assess the main limitations reported by the authors in these processes, and (c) to provide a set of recommendations for best practices in future scale development research. Papers were selected in September 2015, with the search terms “scale development” and “limitations” from three databases: Scopus, PsycINFO, and Web of Science, with no time restriction. We evaluated 105 studies published between 1976 and 2015. The analysis considered the three basic steps in scale development: item generation, theoretical analysis, and psychometric analysis. The study identified ten main types of limitation in these practices reported in the literature: sample characteristic limitations, methodological limitations, psychometric limitations, qualitative research limitations, missing data, social desirability bias, item limitations, brevity of the scale, difficulty controlling all variables, and lack of manual instructions.

<h2>Right answer: It is used to measure long distances in space</h2>
A light year (
) is a distance unit that is approximately 
.
By definition it is <em>the distance that a photon would travel in vacuum during a Julian year (365.25 days) at the speed of light (299 792 458 m/s) at an infinite distance from any gravitational field or field magnetic.
</em>
<em>
</em>
In other words:
It is the distance that light can travel in a year.
This unit is used to measure large distances in space. Therefore the correct answer is D.
Answer:
all of the above are factors
Explanation:
- Factors that impact or control the movement of magma and lava from the volcanoes include a wide array of factors like the composition of magma and lava which is viscous fluid that brings up the intensity of violent eruptions of such as those that have higher silicate content.
- The explosion intensity also depends on the volume and length of the eruption and composition of volcanic products and their eruption environment.
- The rooftop of the volcanoes i.e the upper chambers or vent is also seen as a major important factor controlling the opening of basaltic matter on the surface. In a shield volcano, the eruption matter is not that dense and vicious as compared to the Italian and strombolian volcano that have a high intensity of lava flows.
Answer:
B. distance of the deposit from the source.
Explanation:
The grain size of sedimentary deposit can indicate the distance of the deposit from the source. This is because, when sediment is transported by water, the sediment becomes victim of abrasion. As abrasion occurs, the edges of the grains of deposit are reduced, eventually leading to a rounder shape. However, this process can vary based on the distance of the deposit, the method of transportation and the energy characteristics of the transportation medium.
Answer:
Weathering degrades a rock without changing its location. Erosion, on the other hand, causes rocks -- or particles of rock -- to be carried away from their original locations and deposited elsewhere
