Due to the Composition, different asteroids reflect different percentages of the light falling on them.
What are Asteroids:
- Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets.
- Asteroids are generally made up of rocky material, metals and their size are large in comparison to comets. Asteroid belt is found between Jupiter and Mars.
Composition of Asteroids:
- Most of the asteroids in the Main Belt are made of rock and stone.
- The remaining asteroids are made up of a mix of these, along with carbon-rich materials. Some of the more distant asteroids tend to contain more ices.
We determine reflectivity of asteroids by comparing the brightness of light in the visible spectrum to the brightness of light in the infrared spectrum. The light shining from asteroids is reflected sunlight.
Hence we can say that,
Due to the Composition, different asteroids reflect different percentages of the light falling on them.

- La velocidad de las ondas sonoras es aproximadamente 1469,694 metros por segundo.
- La longitud de onda de las ondas sonoras es 1,470 metros.
1) Inicialmente, debemos determinar la velocidad de las ondas sonoras a través del agua (
), en metros por segundo:
(1)
Donde:
- Módulo de compresibilidad, en newtons por metro cuadrado.
- Densidad del agua, en kilogramos por metro cúbico.
Si sabemos que 
y 
, entonces la velocidad de las ondas sonoras es:
La velocidad de las ondas sonoras es aproximadamente 1469,694 metros por segundo.
2) Luego, determinamos la longitud de onda (
), en metros, mediante la siguiente fórmula:
(2)
Donde 
es la frecuencia de las ondas sonoras, en hertz.
Si sabemos que y 
, entonces la longitud de onda de las ondas sonoras es:
La longitud de onda de las ondas sonoras es 1,470 metros.

Hello
The final light will be white. In fact, each color of the visible spectrum is an electromagnetic wave with its own specific frequency and wavelength. White, instead, does not have a specific frequency: it is the sum of all the different wavelengths of the visible spectrum. Therefore, when recombining the spectrum of the refracted light all the different frequencies recombine together, and their sum gives white light.

Answer:
Answer is: c. It must lose two electrons and become an ion.
Magnesium (Mg) is metal from 2. group of Periodic table of elements and has low ionisation energy and electronegativity, which means it easily lose valence electons (two valence electrons).
Magnesium has atomic number 12, which means it has 12 protons and 12 electrons. It lost two electrons to form magnesium cation (Mg²⁺) with stable electron configuration like closest noble gas neon (Ne) with 10 electrons.
Electron configuration of magnesium ion: ₁₂Mg²⁺ 1s² 2s² 2p⁶.
