n = 1.52

<u>Index of the liquid = 1.52</u>

<u>The type of the liquid is Crown glass.</u>

<u>Explanation:</u>

In finding the index of refraction, we use this formula

n = c/v

where n is the index of refraction

c is velocity of light in vacuum which is constant and is equivalent to 3 \times 10^{8} \mathrm{m} / \mathrm{s}

v is the velocity of light in a particular medium

Here we use 1.97 \times 10^{8} \mathrm{m} / \mathrm{s}

Using the formula,

n = c/v

n = 3 \times 10^{8} / 1.97 \times 10^{8}

n = 1.52284264

n = 1.52

Thus, the index of the liquid is 1.52

The refractive index of the liquid is 1.52. The substance is a crown glass.

<u>Explanation:</u>

Given:

Velocity of light through the substance, v = 1.97 X 10⁸ m/s

Refractive index of the liquid, μ = ?

We know,

μ = \frac{c}{v}

where, c = velocity of light in air

            v = velocity of light in the substance

speed of light in air is 3 X 10⁸m/s

= \frac{3 X 10^8}{1.97 X 10^8} \\\\= 1.52\\

Therefore, refractive index of the liquid is 1.52. The substance is a crown glass.

Which states of matter are significantly compressible?
andreev551 [17]
Hello.


The gaseous state is the more compressible state, because it has the volume of its container.

The liquid state is virtually incompressible, and the solid state compression is very small.

The plasma is another state that has high compression, but in this case the matter is not bound(we don't have the proton in the core of the atom)

Current is produced when charges are accelerated by an electric field to move to a position of lower
Vaselesa [24]
Current is created when charges are quickened by an electric field to move where the position of lower temperature. An electric current is a stream of electric charge. In electric circuits, this charge is regularly conveyed by moving electrons in a wire.

Which statement is true for a car that first goes around a curve of radius r at a constant speed v, and then goes around the sam
sasho [114]
Centripetal force is equal to (mv^2)/r
The way I use to answer these question is to set every variable to 1
m=1
v=1
r=1
so centripetal force =1
then change the variable we're looking at
and since we're find when it's half we could either change it to 1/2 or 2, but 2 is easier to use
m=1
v=2
r=1
((1)×(2)^2)/1=4
So the velocity in the 1st part is half the velocity in the 2nd part and the centripetal force is 4× less
The answer is the centripetal force is 1/4 as big the second time around

4 facts about relative dating?
sasho [114]
Relative dating is used to arrange geological events….

Relative dating puts geologic events in chronological order without requiring that a specific numerical age be assigned to each event….

Relative Dating uses the half life of isotopes to get the exact age of a rock or mineral.
