Answer:

El valor en notación científica es 3.98*10⁻⁶.

Explanation:

La notación científica es una manera rápida de representar un número utilizando potencias de base diez. Esta notación se utiliza para poder expresar muy fácilmente números muy grandes o muy pequeños.

Los números se escriben como un producto:

a*10ⁿ

donde:  

  • a es un número real mayor o igual que 1 y menor que 10, al cual se le agrega un punto decimal después de la primera cifra si se trata de un número que no es entero.
  • n es un número entero, que recibe el nombre de exponente u orden de magnitud. Representa el número de veces que se desplaza la coma. Siempre es un número entero, positivo si se desplaza a la izquierda, negativo si se desplaza a la derecha.

Para escribir el número 0.000003979 en notación científica, se realizan los siguientes pasos:

  • Se mueve la coma decimal hacia la derecha tantos espacios hasta llegar a la derecha del primer dígito.
  • Se escribe entonces este número, que será el coeficiente a en la expresión del producto anterior.  
  • Se escribe la base 10 con el exponente igual a la cantidad de espacios que se mueve la coma. Este es un número negativo porque la coma se desplaza a la derecha.

Entonces, en este caso:

  • a= 3,979 ≅ 3,98
  • n= -6

Entonces,<u><em> el valor en notación científica es 3.98*10⁻⁶.</em></u>

all white dwarfs have masses in a small range—from about 0.5 to almost 1.4 malchemist sun symbol. why? (select all that apply.)
Minchanka [31]

A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.

<h3>What are white dwarfs?</h3>

White dwarfs are stellar core remnant composed mostly of electron-degenerate matter.

White dwarf is very dense due to its large mass and smaller volume.

<h3>Reasons for comparable mass of white dwarfs and Sun</h3>
  • Stars with main sequence masses less than about 0.5 solar masses cannot ignite the helium fusion required to become white dwarfs.
  • A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.
