Which part of earths surface has the greatest rotational speed

Physics
1 answer:
Anni [7]4 years ago
6 0
Every point on the surface must have the same rotational speed.
Otherwise some places would rotate away from other places.

If the next block of your city rotated faster than the block that you live on,
then you could sit at home, look out the window, and watch your school
rotate past your house.

The map of the continents on the Earth would change constantly.

A charge of 6.4x 10^-7 c experiences an electric force of 1.8 x10^-1 N. What is the electric field strength ?
laila [671]
Electric
field strength = Electric force/charge
E = F/q
E = (1.8×10^-1) / (6.4×10^-7)
E = 2.81×10^5 NC^-1

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>
