Tara predicts the number of paper clips attracted by the magnet

muminat

The responding variable refers to the variable that changes as the independent variable is being manipulated. In this case, the responding variable is the number of paper clips attracted by the magnet.

An experiment must include a dependent (responding) variable and an independent variable. As the independent variable is manipulated during the experiment, the dependent (responding) variable changes accordingly.

In this case; the independent variable is temperature while the dependent (responding) variable is the number of paper clips attracted by the magnet.

There are<br><br> molecules of carbon dioxide (CO2) in 102.5 grams.

Gekata [30.6K]

Answer:

1.403x10²⁴ molecules

Explanation:

In order to calculate how many molecules of CO₂ are there in 102.5 g of the compound, we first<u> convert grams to moles</u> using its <em>molar mass</em>:

102.5 g ÷ 44 g/mol = 2.330 mol CO₂

Now we <u>convert moles into molecules </u>using <em>Avogadro's number</em>:

2.330 mol * 6.023x10²³ molecules/mol = 1.403x10²⁴ molecules

Which quantity is equivalent to the product of the absolute index of refraction of water and the speed of light in water?

givi [52]

The quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.

<h3>What is the speed of light?</h3>

Speed of light is the rate of speed though the light travels. To find the speed of light in any medium, the following formula is used.

$v=\dfrac{c}{n}$

Here, (n) is the index of reaction and (c) is the speed of light in the vacuum. The speed of light in the vacuum is almost equal to the 3.0×10⁸ m/s.

Now the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water has to be find out.

The above formula can be written as,

$v=\dfrac{c}{n}\\vn=c\\c=vn$

Here, the product of index of refraction and speed of light is equal to the speed of light in vacuum. This will be true for water as well.

Thus, the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.
