Answer:

Steel is mostly composed of iron and carbon. It contains small amounts of manganese and even smaller amounts of silicon, phosphorous, oxygen, sulfur, and other elements.

...

Density of Steel.

carbon steel - 7.86

stainless steel - 7.9

If you add alloying elements such as tungsten, chrome or manganese to improve the steel, the density will change. So the long answer is that the density of steel can vary between 7.75 and 8.05."

A thin oil slick (no=1.50) floats on water (nw=1.33). When a beam of white light strikes this film at normal incidence from air,
Sedbober [7]

Answer:

The (minimum) thickness of the oil slick is 325 nm.

Explanation:

Let the (minimum) thickness of the oil slick = t_{o}

Therefore:

2t_{o} = (m_{red}+\frac{1}{2})*λ_{red}/n_{o}       (1)

similarly,

2t_{o}=(m_{violet}+\frac{1}{2})*λ_{violet}/n_{o}                                (2)

Thus, equation 1 = equation 2

(m_{red}+\frac{1}{2})*λ_{red} /n_{o} = (m_{violet}+\frac{1}{2})*λ_{violet}/n_{o}

Where:

λ_{red} = 650 nm

λ_{violet} = 390 nm

n_{o} = 1.5

Therefore:

\frac{2m_{violet}+1 }{2n_{red}+1 }=650/390=5/3

This shows that,

m_{violet}=2

m_{red}=1

Thus, using equation 2

t_{o}=\frac{5*390}{2*2*1.5} =325 nm

How is aperture measured? What do the measurements mean?
gulaghasi [49]
Aperture is measured in F-stops, in which the f-stops is the amount of light allowed to pass through the aperture, which simply put means that the smaller the aperture, the higher the f-stops. What it does is reduce the amount of light that reaches the film, so the higher the f-stops, the less light reaches the film.

En un instante pasa por A un cuerpo con MRU de 20 m/seg, 5 segundos después pasa en su persecución, por el mismo punto A otro cu
sukhopar [10]

Answer:

Los cuerpos se encuentran luego de 15 segundos a los 300 metros.

Explanation:

El movimiento rectilíneo uniforme (MRU) es el movimiento que describe un cuerpo o partícula a través de una línea recta a velocidad constante. Es decir, que en este caso el movimiento es lineal en una única dirección  y la velocidad de desplazamiento es constante.

La posición del cuerpo después de un tiempo se calcula a partir de la posición inicial y de la velocidad del cuerpo mediante la expresión:

x=x0+v⋅t

donde:

  • x0 es la posición inicial.
  • v es la velocidad que tiene el cuerpo a lo largo del movimiento.
  • t es el intervalo de tiempo durante el cual se mueve el cuerpo.

En este caso, si el tiempo empleado por el primer cuerpo es t, el del segundo que sale 5 segundos más tarde será t-5. Siendo la velocidad del primer cuerpo 20 m/s y la del segundo cuerpo 30 m/s, entones la posición de cada uno será:

x1 = 20 m/s* t

x2 = 30 m/s* (t - 5 s)

Ambos se encuentran cuando sus posiciones son iguales:

x2=x1

30*(t - 5) = 20*t

30*t - 30*5= 20*t

30*t - 150 = 20 t

30*t - 20*t= 150

10*t= 150

t= 150÷10

t=15 segundos

Reemplazando en la expresiones de posición obtienes:

x1 = 20 m/s* 15 s= 300 m

x2 = 30 m/s* (15 s - 5 s)= 300 m

<u><em>Los cuerpos se encuentran luego de 15 segundos a los 300 metros.</em></u>
