Remark

There fewer people who see it the better if you are still a little uncertain about what to say or how to say it.

Given the remark, I think this is the place to start. Mothers are especially tolerant about listening to a first time speech. The criticism is very light. You will benefit most by hearing what it sounds like. I would pick A as the answer.

You have an awful lot of nerve if you are going to talk in front of an audience that large with an unprepared speech. Good luck.

At a science fair is not a bad choice. The groups are small, and you will get to explain your project many times before you see a judge. That will give you the necessary experience to polish what you have to say.

How do you feel about talking in front of classmates with a teacher giving you a mark? Not the best place to start.

Conclusion. Please Read

Where you start depends on what you are talking about. The science fair option is a good one if that is your intended audience. For all other assignments, I'd pick A. If this is a question that actually came from a physics class then pick C.

A paperweight consists of a 8.55-cm-thick plastic cube. Within the plastic a thin sheet of paper is embedded, parallel to opposi

ella [17]

Answer:

$\mu=1.5322$

Explanation:

Given:

Thickness of the paperweight cube, $x=8.55\ cm$

apparent depth from one side of the inbuilt paper in the plastic cube, $i=4.02\ cm$

apparent depth from the other side of the inbuilt paper in the plastic cube, $i'=1.56\ cm$

Now as we know that refractive index is given as:

$\rm \mu=\frac{real\ depth}{apparent\ depth}$

Let the real depth form first side of the slab be, $d$

Then the depth from the second side of the slab will be, $d'=x-d=8.55-d$

Since refractive index for an amorphous solid is an isotropic quantity so it remains same in all the direction for this plastic.

$\mu=\mu'$

$\frac{d}{i} =\frac{d'}{i'}$

$\frac{d}{4.02}=\frac{8.55-d}{1.56}$

$d=6.1597\ cm$

Now the refractive index:

$\mu=\frac{d}{i}$

$\mu=\frac{6.1596}{4.02}$

$\mu=1.5322$

The elements that do not ordinarily form compounds are

ololo11 [35]

The noble gasses, they are the elements on group 18 of the periodic table and do not usually form compounds. The noble gases are as follows: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Hope this helped :)
