From what we know, we can confirm that doing this may dirty and cause harm to your 40x lens.

<h3 /><h3>Why would this cause harm to your lens?</h3>

Oil immersion is a technique that can be quite handy when attempting to view hard-to-see specimens. However, This should be done only with lenses that are made specifically for this, so revolving the nosepiece in the wrong direction will expose the 40x lens to the oil, for which it is not designed, and may cause harm to the equipment.

Therefore, we can confirm that the 40x lens could get dirty with oil if you move the revolving nosepiece in the wrong direction after viewing it under oil immersion.

Liula [17]
The question above is incomplete, the options attached tot he question are given below:
A. A structure made of building blocks.

 The blocks of the same structure bundled in a pile.

B.  A snowman.

 The melted remains of the same snowman.

C. A lump of clay.

The same lump broken into three pieces.

D. 1 cup of water and one gram of salt, separated.

 The same cup of water with one gram of salt mixed in.

E. One apple.

 The same apple cut into slices.

ANSWER:

The correct options are these:

B. A Snowman and the melted remain of the same snowman.

C. Lump of clay and the same clay broken into three pieces.

E. One apple and the same apple cut into slices.

For all the three answers listed above, the mass of the pairs will remain the same because nothing has been taken out of them and nothing is added to them, they were just changed from one form to another. The other options are wrong because, something got added to the original material.

Good evening! Does anyone know this? Earth Science
riadik2000 [5.3K]

The fraction of Earth's radius (6371 km) relative to the thickness of the oceanic (7.5 km) and continental crust (35 km) is 0.12 and 0.55, respectively.    

What we know:

  • The average radius of Earth (E) = 6371 km
  • The average thickness of oceanic crust (O) = 7.5 km
  • The average thickness of continental crust (C) = 35 km

We need to convert all the above units from kilometers to miles:

E = \frac{0.6214 mi}{1 km}*6371 km = 3958.9 mi

O = \frac{0.6214 mi}{1 km}*7.5 km = 4.7 mi

C = \frac{0.6214 mi}{1 km}*35 km = 21.7 mi

Now, we can calculate the fraction of Earth's radius relative to each type of crust, with the given equation:

X = \frac{avg. \: thickness}{avg. \: radius} \times 100

  • <u>For the oceanic crust (O)</u>:

X = \frac{4.7 mi}{3958.9 mi}\times 100 = 0.12

  • <u>For the continental crust (C)</u>:

X = \frac{21.7 mi}{3958.9 mi}\times 100 = 0.55

Therefore, the fraction of Earth's radius relative to the oceanic and continental crust is 0.12 and 0.55, respectively.

You can see another example of calculation of fractions of Earth's radius here: brainly.com/question/4675868?referrer=searchResults

I hope it helps you!
