Depends on what type of mirror that is. I am going to assume this is a plain mirror (from the phrase), which means the height and width of the object and image is exactly the same.

9. Albert Einstein.
10. Edwin Hubble
11. Karl Jansky.
12. Grote Weber.
Explanation:
1. Ptolemy: said sun revolved around earth.

3. Tycho Brahe: analyzed motions of planets.
4. Galileo Galilei: first used refracting telescope for astronomy.
5. Isaac Newton: invented reflecting telescope.
6. William Herschel: discovered the planet Uranus.
7. Johann Galle: discovered the planet Neptune.
8. Clyde Tombaugh: discovered the dwarf planet Pluto.
9. Albert Einstein: developed special and general theories of relativity.
10. Edwin Hubble: demonstrated that universe is expanding.
11. Karl Jansky: discovered radio waves from the center of the Milky Way.
12. Grote Weber: an amateur astronomer who built the first radio telescope.
All of the factors that need to be considered when determining an object's terminal velocity are the object's weight and area it presents, as well as air density.
<em>option </em><em>C </em><em>is the correct answer</em>
<h3>What is terminal velocity?</h3>
Terminal velocity is obtained when the speed of a moving object is no longer increasing or decreasing. That is the object's acceleration (or deceleration) is zero.
Mathematically, the formula for terminal velocity is given as;
V = √(2mg)/(ρAC)
where;
- m is the mass of the falling object
- g is the acceleration due to gravity
- ρ is the density of the fluid through which the object is falling
- A is the projected area of the object
- C is the drag coefficient
Thus, the variables to consider in determining terminal velocity of an object incudes the area, density of air, mass, etc.

Answer:
Dencidad = 600 kg/m³
Explanation:
Dados los siguientes datos;
Lado del cubo = 10 cm a metros = 10/100 = 0,1 m
Masa = 0,6 kg
Para encontrar la densidad;
En primer lugar, determinaríamos el volumen del cubo usando la fórmula;
Volumen del cubo = lados³
Volumen del cubo = 0.1³
Volumen del cubo = 0.001 m³
Ahora, podemos encontrar la densidad usando la fórmula;
Dencidad = masa/volumen
Dencidad = 0,6/0,001
Dencidad = 600 kg/m³
