Answer:
Explanation:
Given
Radius of curvature=20 m
Speed of cyclist=17.5 m/s
we know that velocity during a turn is given by
where v=speed
r=radius of curvature
=angle of banking
=coefficient of friction
g=acceleration due to gravity
here 
thus
Independent variable
To achieve internal validity, a researcher must design and conduct experiments where only the independent variable can be the cause of the results.
<h3>What are internal and external validity?</h3>
The degree to which a study shows a reliable cause-and-effect relationship between a therapy and a result is known as internal validity. Internal validity also shows that a particular investigation enables the exclusion of competing hypotheses for a finding. Internal validity is not a binary term, either yes or no. Instead, we evaluate how confident we can be in a study's conclusions depending on whether it avoids pitfalls that could cast doubt on the results.
The term external validity describes how effectively the results of a study should be extrapolated to other contexts. In other words, the generalizability of the results is the subject of this form of validity. For instance, are the results generalizable to different populations, environments, circumstances, and eras? Transferability is a different word that describes external validity and a qualitative research design. Whether results apply other circumstances with similar characteristics is referred to as transferability.

Although some cases are decided based on written briefs alone, many cases are selected for an "oral argument" before the court.
