The gem amethyst gets its purplish color from trace amounts of iron and aluminum within its crystal lattice structure. Amethyst is a variety of quartz, which is a silicon dioxide mineral. The coloration occurs due to the presence of impurities or color centers that interact with light, absorbing certain wavelengths and transmitting others.

In the case of amethyst, the purple color is primarily attributed to the presence of iron impurities (Fe3+) within the crystal lattice of quartz. The iron impurities absorb certain wavelengths of light in the visible spectrum, particularly in the green and yellow regions, leaving behind the purplish hues to be transmitted to our eyes.

The exact shade of purple can vary in amethyst gemstones, ranging from light lilac to deep violet, depending on the concentration of iron impurities and other factors during their formation. Heat treatment or exposure to radiation can also influence the color of amethyst, but the natural variety gets its beauty from the fascinating interplay of these impurities within the crystal structure.

Energy is transformed and transferred in a thermodynamic system. Option B is correct

First law of thermodynamics:

It states the energy neither be created nor destroyed. It change its form from one to another. It is also known as law of conservation of energy.

It is given by the formula,

Where,

- change in internal energy

-    heat added

-    work done by the system

Since, heat is a form of energy, hence it is follow the principle of conservation of energy.

Therefore, energy is transformed and transferred in a thermodynamic system. Option B is correct

Answer:

2: A,D,E or 1,4,5

3: B

4: B

5: 12 joules

6: 53 joules

7: B,C,E or 2,3,5

8: 2,4,3,1

9: Electrical energy in the stove is transformed into heat. The heat flows to the water in the kettle, increasing the internal energy of the water. As the energy in the water increases, the water molecules move faster until the liquid water becomes water vapor. The water vapor does work on the whistle, causing it to make a sound. Energy is neither created nor destroyed, it has simply changed form in the process.

To solve this question, we need to use the component method and split our displacements into their x and y vectors. We will assign north and east as the positive directions.

The first movement of 25m west is already split. x = -25m, y = 0m.

The second movement of 45m [E60N] needs to be split using trig.
x = 45cos60 = 22.5m
y = 45sin60 = 39.0m

Then, we add the two x and two y displacements to get the total displacement in each direction.

x = -25m + 22.5m = -2.5m
y = 0m + 39.0m

We can use Pythagorean theorem to find the total displacement.
d² = x² + y²
d = √(-2.5² + 39²)
d = 39.08m

And then we can use tan to find the angle.
inversetan(y/x) = angle
inversetan(39/2.5) = 86.3

Therefore, the total displacement is 39.08m [W86.3N]

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K. In the inner solar system, only substances with very high melting points would have remained solid. All the rest would have vaoprized. So the inner solar system objects are made of iron, silicon, magnesium, sulfer, aluminum, calcium and nickel. Many of these were present in compounds with oxygen. There were relatively few elements of any other kind in a solid state to form the inner planets. The inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres. In the outer regions of the solar system where it was cooler, other elements like water and methane did not vaporize and were able to form the giant planets. These planets were more massive than the inner planets and were able to attract large amounts of hydrogen and helium, which is why they are composed mainly of hydrogen and helium, the most abundant elements in the solar system, and in the universe
