How is wavelength related to the different colors we see in a rainbow?

1 answer:

6 0

As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

UN ELEVADOR DE TALLER TIENE PISTONES DE ENTRADA Y DE SALIDA , CON DIAMETRO DE 15 cm Y 40 cm RESPECTIVAMENTE, SE USA EL ELEVADOR

Studentka2010 [4]

Answer:

a) La fuerza que se aplica al pistón de entrada tiene una magnitud de 1968.75 newtons.

b) La presión que se aplica al pistón de entrada es de 111408.460 pascales.

Explanation:

a) Este problema se resuelve mediante el Principio de Pascal, el cual establece que la presión dentro de un sistema hidráulico cerrado es la misma en cualquiera de sus puntos. Por tanto, podemos calcular la fuerza aplicada al pistón de entrada mediante la siguiente relación:

$\frac{F_{in}}{\frac{\pi}{4}\cdot D_{in}^{2}} = \frac{M\cdot g}{\frac{\pi}{4}\cdot D_{out}^{2} }$

$F_{in} = \left(\frac{D_{in}}{D_{out}} \right)^{2}\cdot M\cdot g$ (1)

Where:

$F_{in}$ - Fuerza aplicada al pistón de entrada, en newtons.

$D_{in}$ - Diámetro del pistón de entrada, en metros.

$D_{out}$ - Diámetro del pistón de salida, en metros.

$M\cdot g$ - Peso del carro, en newtons.

Si sabemos que $D_{in} = 0.15\,m$ , $D_{out} = 0.40\,m$ y $M\cdot g = 1.4\times 10^{4}\,N$ , entonces la fuerza aplicada al pistón de entrada es:

$F_{in} = \left(\frac{0.15\,m}{0.40\,m} \right)^{2}\cdot (1.4\times 10^{4}\,N)$

$F_{in} = 1968.75\,N$

La fuerza que se aplica al pistón de entrada tiene una magnitud de 1968.75 newtons.

b) Ahora, presión aplicada al pistón de entrada ( $p$ ), en pascales, queda descrita a través de la siguiente expresión:

$p = \frac{F_{in}}{\frac{\pi}{4}\cdot D_{in}^{2} }$ (2)

Si sabemos que $F_{in} = 1968.75\,N$ y $D_{in} = 0.15\,m$ , entonces la presión aplicada al pistón de entrada es:

$p = \frac{1968.75\,N}{\frac{\pi}{4}\cdot (0.15\,m)^{2} }$

$p = 111408.460\,Pa$

La presión que se aplica al pistón de entrada es de 111408.460 pascales.

Phantasy [73]

Answer:

Power = 9.75 ×10^8 $\frac{kgm^2}{s^3}$

Explanation:

Power is rate of change of energy.
Here gravitational energy is transferred to kinetic energy of water at a definite rate.

For one second 650m^3 of water flows out down to 150m oh depth.

So, the energy at a height of 150m is transformed to kinetic energy.

for a second,

650m^3 of water flows down ⇒ (1000kg/m^3 × 650m^3) = 6.5×10^5kg of warer flos down.

The total gravitational potential energy stored in water is

= mass of water × height× gravity

= 6.5 ×10^5 × 150 × 10 = 9.75 ×10^8 $\frac{kgm^2}{s^2}$

As it is transformed in a second it is also equal to Power.
