Cross-sectional research offers several advantages, including the ability to collect data from a large population quickly and efficiently, which allows for the examination of multiple variables at a single point in time. This type of study is cost-effective and relatively easy to conduct, making it suitable for exploratory research. Additionally, it provides a snapshot of the relationships between variables, enabling researchers to identify potential associations and trends without the need for long-term follow-up. However, it is important to note that cross-sectional research cannot establish causality.
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
Other things being equal, more cross-sectional area will cause less resistance.

Cross sectional
Cross sequential studies combine both longitudinal and cross sectional methods in an attempt to both shorten the length of the research and minimize developmental assumptions
cross-sectional
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.
advantage of cross sectional study?
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
Cross-sectional research studies a group of individuals at one specific point in time to understand relationships or differences between variables. Longitudinal research, on the other hand, involves studying the same group of individuals over an extended period to track changes and development in variables of interest.
The quickest way to study changes over the life span is through cross-sectional research. Cross-sectional studies (also known as Cross-sectional analysis) form a class of research methods that involve observation of some subset of a population of items all at the same time, in which, groups can be compared at different ages with respect of independent variables, such as IQ and memory ...

the larger the cross sectional area, the smaller the resistance
