What else can I help you with?
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
What happens to the cross-sectional area of metal wire if you double the diameter?
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
How does the cross sectional area of wire affect resistance?
Other things being equal, more cross-sectional area will cause less resistance.
What wire has the greatest cross-sectional area?
The wire with the greatest cross-sectional area is typically a thick copper wire, such as that used in electrical applications, measured in American Wire Gauge (AWG). For example, a 0000 AWG (4/0) wire has a cross-sectional area of approximately 53.5 mm². In general, as the AWG number decreases, the wire diameter and cross-sectional area increase. Thus, the thickest wire in standard gauge systems will have the greatest cross-sectional area.
Which has the greatest cross sectional area?
9 AWG
Is CROSS sectional study a retrospective study?
Yes, We can design a cross sectional study which its data collected in a retrospective format, so this study is called cross sectional retrospective study.
What is the difference between cross sectional and cross sequential?
Cross-sectional design involves studying different groups of individuals at a single point in time, whereas cross-sequential design combines both cross-sectional and longitudinal elements by studying different age groups over a period of time. Cross-sectional design allows for quick and easy comparisons between different age groups, while cross-sequential design allows researchers to track the same individuals as they age.
Advantages of cross-sectional research design?
A cross sectional design is a developmental design where multiple samples of participants of different ages are tested at once. Cross sectional research design gathers data about different ages at the same time. Also participants only have to commit for a short time.
A clinical child psychologist compares the depression scale scores of urban foster children who range from 5 to 12 years of age This research design is?
Cross sectional
Which design does not control for cohort effects?
A cross-sectional design does not control for cohort effects because it involves studying different age groups at the same point in time, making it difficult to separate age effects from cohort effects.
When a sequential study design is used which disadvantages of a cross sectional design is eliminated?
The collection of data and statistical analysis are time-consuming
When a sequential study design is used which disadvantages of a cross-sectional design is eliminated?
The collection of data and statistical analysis are time-consuming
Advantage of cross sectional study?
advantage of cross sectional study?
How do you do a cross sectional area of a rectangle?
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
How does cross sectional area affect resistance?
the larger the cross sectional area, the smaller the resistance
What is the meaning of Cross sectional area in a river?
Cross Sectional Area = Width x Average Depth
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
