Un espejo convexo y un cóncavo tienen la misma distancia radial igual a 5m. La separación entre espejos es de 3 veces la distanc

ia focal. Si un objeto de altura 1.75m que se encuentra entre estos dos espejos, se refleja en ambos, determine la relación de alturas entre las imágenes que se forman.

Answer:

La altura de la imagen producida por el espejo cóncavo es 5 veces la altura de la imagen producida por el espejo convexo

Explanation:

La ecuación de espejo para espejos cóncavos viene dada por la relación;

\dfrac{1}{f} = \dfrac{1}{d_o} + \dfrac{1}{d_i}

Para espejos convexos, tenemos;

-\dfrac{1}{f} = \dfrac{1}{d_o} - \dfrac{1}{d_i}

Dado que la separación de los dos espejos = 3 × f

La ubicación del objeto = Entre los espejos = f × 3/2

Altura del objeto = 1.75 m

Radio de curvatura de los espejos = 5 m.

Por lo tanto, f = 5/2 = 2.5 m.

Distancia del objeto = f × 3/2 = 3.75 m.

Para el espejo cóncavo, tenemos que la distancia de la imagen se puede encontrar de la siguiente manera;

\dfrac{1}{2.5} = \dfrac{1}{3.75} + \dfrac{1}{d_i}

Lo que da;

\dfrac{2}{5} = \dfrac{4}{15} + \dfrac{1}{d_i}

\dfrac{1}{d_i} = \dfrac{2}{5} - \dfrac{4}{15} = \dfrac{2}{15}

d_i = 15/2 = 7.5 m

Que es una imagen real

m = \dfrac{-d_i}{d_o}  = \dfrac{-7.5}{3.75} = -2

Por lo tanto, la imagen es real, invertida y es dos veces la altura del objeto.

La altura de la imagen, h_i = m × Altura del objeto = -2 = -3.5 m

Para el espejo convexo, tenemos que la distancia de la imagen se puede encontrar de la siguiente manera;

-\dfrac{1}{2.5} = \dfrac{1}{3.75} - \dfrac{1}{d_i}

Lo que da;

-\dfrac{2}{5} = \dfrac{4}{15} - \dfrac{1}{d_i}

-\dfrac{1}{d_i} = -\dfrac{2}{5} - \dfrac{4}{15} = -\dfrac{2}{3}

d_i = 3/2 = 1.5 m

Que es una imagen real

m = \dfrac{-d_i}{d_o}  = \dfrac{-1.5}{3.75} = -\dfrac{2}{5}

Por lo tanto, la imagen es real, invertida y es 2/5 veces la altura del objeto

La altura de la imagen, h_i = m × Altura del objeto= -2/5 × 1.75 = -0.7 m

Por lo tanto, cuando la altura de la imagen formada por el espejo cóncavo se divide por la altura de la imagen formada por el espejo convexo, tenemos;

\dfrac{h_{(i, concave)}}{h_{(i, convex)}} =\dfrac{-3.5}{-0.7} = 5

Por lo tanto, la altura de la imagen producida por el espejo cóncavo = 5 veces la altura de la imagen producida por el espejo convexo

Waves begin to "feel bottom" when the depth of water is
LekaFEV [45]
I think the correct answer would be one half the wavelength. Waves would "feel bottom" when the water is at the depth of 0.5 of the wavelength. "Feel bottom" is a term used to describe that the depth of water affects the wave properties. Hope this answers the question.

A sliver cylindrical rod has a length of 0.5 m and a radius of 0.4 m, find the density of the rod if it's mass is 2.640 kg
Serga [27]

Answer:

Density=10.50kg/m³

Explanation:

Solution,\\Height(h)=0.5m\\Radius(r)=0.4m\\Now, \\Volume=\pi r^{2} h\\\\Volume=\pi *(0.4m)^{2} *0.5m\\\\Volume=0.251327m^{3} \\\\Again,\\\\Density=\frac{mass}{volume} \\\\Density=\frac{2.640kg}{0.251327} \\\\Density=10.50kg/m^{3}

What will occur if a resistor with high resistance is inserted into a circuit?
Anton [14]
If the resistor is in series with the rest of the circuit then a is the correct answer. The voltage across the resistor in series with another resistor is
V \frac{R}{R+r}
where R is the big resistor and r is the small one and V is the total voltage drop across both.  This is called a voltage divider
