It might be challenging to estimate the thickness of a thin layer of a substance. If a micrometer is available and the material is not too thin, it can be used to measure thickness directly. In the absence of a micrometer, thickness measurement must be done indirectly.
<h3>How is the thickness of aluminum foil determined?</h3>
All that is required of us is to cut a piece of the problematic aluminum foil, measure its height and length (so that we can determine its area), crumple the foil into a small ball, and weigh it using a milligram balance. The information needed to indirectly calculate the aluminum foil's thickness will then be available to us.
<h3>What measurement unit is best for representing the thickness of the foil?</h3>
The foil will likely be roughly a micrometer thick, which translates to a thickness of 1 x 
cm in centimeters. Since an atom is roughly 
m in size, there will be 1 x 
atoms in a unit of 1 x cm.

Answer: c) Repeated measures
Explanation:
Repeated measure designing is the design in which same variable's multiple measures are taken under different condition but on the similar subject.It can also be taken over different time period for researching.
According to the question.,Eric is using repeated measures design by researching on people's enjoyment wen drinking coffee, teas and milk at certain time.Thus study is on the similar subject with same participant with repeating act.
Other options are incorrect because research design is not based on posttest ,pretest or concurrent measures .Thus, the correct option is option(c).
