A situation which best describes a student that is engaged in active learning is: C. a student records questions to ask the teacher about a concept.
<h3>What is a question?</h3>
A question can be defined as a group of words or sentence that are developed, so as to elicit an information in the form of answer from an individual such as a student or teacher.
This ultimately implies that, questions are primarily formulated by professionals to test the understanding of an individual. Also, questions should be formulated by a good reader or student so as to enable him or her connect to a story and understand a concept better.
In this context, we can reasonably infer and logically deduce that a situation which best describes a student that is engaged in active learning is when a student records questions to ask the teacher about a concept.

Answer:
0.31 μm
Explanation:
this question wants us to Determine the depletion region width, xn, in the n-side in unit of μm. using the information below.
density in the p-side = 5.68x10^16
density in the n-side = 1.42x10^16
= √(1.42x10⁵)(1.76056335x10⁻¹⁷ + 7.042253521x10⁻¹⁷)(1.2)
= √150.74x10⁻¹¹
= 3.882x10⁻⁵
approximately 0.39μm
xn = 0.39 x 0.8
= 0.31μm
0.31 um is the depletion region width. thank you!
Answer:
The volume percentage of graphite is 10.197 per cent.
Explanation:
The volume percent of graphite is the ratio of the volume occupied by the graphite phase to the volume occupied by the graphite and ferrite phases. The weight percent in the cast iron is 3.2 wt% (graphite) and 96.8 wt% (ferrite). The volume percentage of graphite is:
Where:
- Volume occupied by the graphite phase, measured in cubic centimeters.
- Volume occupied by the graphite phase, measured in cubic centimeters.
The expression is expanded by using the definition of density and subsequently simplified:
Where:
, 
- Masses of the ferrite and graphite phases, measured in grams.
- Densities of the ferrite and graphite phases, measured in grams per cubic centimeter.
If 
, 
, 
and 
, the volume percentage of graphite is:
The volume percentage of graphite is 10.197 per cent.
