The statement 'what stars are made of' is an example of a question that could be answered using cosmological models.

<h3>What are cosmological models?</h3>

Cosmological models are scientific models to understand the forces that shape the structure of the universe.

The cosmological model answers diverse types of inquiries such as ''what stars are made of' because this model describes the composition of celestial bodies (including stars) in the universe.

The cosmological model can examine different questions about the universe including its composition, structure, evolutionary trajectories, etc.

In conclusion, the statement 'what stars are made of' is an example of a question that could be answered using cosmological models.

Answer:

<h3><em>What is filteration</em><em>:</em></h3>

Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. ... In some processes used in the production of chemicals, both the fluid filtrate and the solid filter cake are recovered.

<h3><em>When</em><em> </em><em>do</em><em> </em><em>we</em><em> </em><em>use</em><em> </em><em>it</em><em>:</em></h3>

<em>Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.</em>

<h3><em>In</em><em> </em><em>order</em><em> </em><em>to</em><em> </em><em>separate</em><em> </em><em>a</em><em> </em><em>salt-water</em><em> </em><em>mixture</em><em>,</em></h3><h3><em>should</em><em> </em><em>a</em><em> </em><em>student</em><em> </em><em>use</em><em> </em><em>filtration</em><em>:</em></h3>

The mixture can be separated by filtration, by dissolving the mixture in water. Salt will dissolve in the water, whereas sand will not.

A summary about liquid
sdas [7]

Answer:

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

fiasKO [112]

Answer:

Charle's Law

Explanation:

<em>...cold it goes flat because the volume of air inside the  ball has been reduced. </em>

<em />

In this scenario, the lower the temperature  the lower the volume. This means that there's a direct proportional relationship between the volume and temperature.

This relationship is presented by Charles law. Charles law states that the volume occupied by a fixed mass of gas is directly proportional to its absolute temperature.

A capacitor has a peak current of 310 μa when the peak voltage at 300 khz is 3.0 v .
Ket [755]
I think the question for this problem, is to find the capacitance. The working equation would be:

C = Q/V,
where
Q = It

Since f = 1/t, t = (1/300 kHz)(1 kHz/1,000 Hz) = 3.33×10⁻⁶ s
So,
Q = (310×10⁻⁶ A)(3.33×10⁻⁶ s)
Q = 1.033×10⁻⁹ C

Thus,
C = (1.033×10⁻⁹ C)/(3 V)
<em>C = 3.44×10⁻¹⁰ F</em>
