The index of the refraction is 0.898 and the index of the refraction is less than one which is unreasonable because the speed of the light can't be more than c.

<h3>What is refraction?</h3>

The phenomenon bending of a wave as it crosses from one medium to another is said to be refraction. The difference in density is the cause of the bending.

Refraction is a term that is used to describe the phenomenon of refraction."The change in direction of a wave traveling through one medium to another is known as refraction."

From the Snell's law:

nsinФ = n'sin∅

We have n' = 1.33, ∅ = 10.0°, Ф = 14.9°

nsin110.0° = 1.33×sin14.9°

n = 0.898

Because the speed of light cannot be greater than c, the index of refraction is less than one, which is illogical.

It is illogical to assume that the angle of refraction is excessively large in relation to the angle of incidence.

Thus, the index of the refraction is 0.898 and the index of the refraction is less than one which is unreasonable because the speed of the light can't be more than c.

= 61.20

for the half an hour, divide 6.80 by 2

it would be 3.40

CUALES SON LOS GRADOS PARA HACER UNA GRAFICA DE PASTEL, CON LOS SIGUIENTES PORCENTAJES( 20%,50%,10%)
svlad2 [7]

Answer:

Lo primero que debemos saber, es que la gráfica de pastel nos permite dividir a una población, la cual sería el 100%, en porcentajes menores que representan algo.

En este caso tenemos los porcentajes 20%, 50%, 10%  (notar que no suman 100%, entonces nos falta algún porcentaje)

Bueno, como sabemos el gráfico (el cual es un círculo) representa el 100%.

Y en un círculo, tenemos un ángulo de 360°

Entonces comenzamos con la equivalencia:

360° = 100%

Entonces, ¿a que grado corresponde el 50%? Planteamos la ecuación:

x = 50%

Si tomamos el cociente entre las ecuaciones:

x = 50% y  360° = 100%

obtenemos:

x/360° = 50%/100%

resolviendo para x, obtenemos:

x = (50%/100%)*360° = 0.5*360° = 180°

Para los otros porcentajes hacemos lo mismo.

Para el de 20% tenemos:

y = 20%

planteamos la ecuación:

y/360° = 20%/100%

y = 0.2*360° = 72°

Finalmente, para el de 10% tendremos:

z = 10%

planteando la ecuación como antes:

z/360° = 10%/100%

z = 0.1*360 = 36°

Asi, hemos encontrado los grados correspondientes para cada porcentaje.
