Why would the use of a ruler not be effective to measure the thickness of your foil?

1 answer:

3 0

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 $10^{-4}$ cm in centimeters. Since an atom is roughly $10^{10}$ m in size, there will be 1 x $10^{4$ atoms in a unit of 1 x $10^{-4}$ cm.

So parties use different methods some are subterfuge, that is why option B is my answer. because from the question, both parties are not agreeing on terms and they want to gain information to be used against each other, what can be seen right in the passage of the question has "Subterfuge".
