My response is that Yes, Focusing a camera changes the distance between the lens and the film. Hence the eye is focus by changing the distance between the lens and the retina.

The mechanism by which the eye is able to achieve focus is through altering the separation of the lens and the retina. The eye comprises a pliant lens which is held by ligaments and has the ability to vary its shape to accurately focus on objects situated at varying distances

As we look at distant objects, the ciliary muscles located in our eyes slacken, leading to a reduction in the curvature of the lens and making it less rounded.

The periodic signal is a signal composed of multiple frequencies, so we are going to solve it by Fourier analysis. fundamental frequency is the lowest frequency that a periodic signal can have.

In Fourier analysis, any periodic function can be represented as a sum of harmonic waves whose frequencies are multiples of the fundamental frequency. Therefore, if we can find the fundamental frequency, we can find the other harmonics and ultimately represent x(t) as a sum of them.

What is the fundamental frequency?The fundamental frequency is the lowest frequency that a periodic signal can have. It is the inverse of the period T, which is the time it takes for one full cycle of the waveform. Thus, the fundamental frequency must be a multiple of both frequencies.

Explanation:

A contractor has a job that should be completed in 100 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 130 days. Of the 80 men, 50 are each paid ₱120.00 a day, 25 at ₱180.00 a day, and 5 at ₱250.00 a day. For each day beyond the original 100 days, a contractor has to pay ₱500.00.

liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.

b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.

The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows:  $$LD = (130-100) \cdot 500 = ₱15,000.00$$.

Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$

Thus, we can see that the contractor would save ₱48,900.00 by employing more men and not paying the fine.

Answer:

La probabilidad pedida es \(0.820196\)

Explanation:

Sabemos que la probabilidad de que un nuevo producto tenga éxito es de 0.85. Sabemos también que se eligen 10 personas al azar y se les pregunta si comprarían el nuevo producto. Para responder a la pregunta, primero definiremos la siguiente variable aleatoria :

\(X:\) '' Número de personas que adquirirán el nuevo producto de 10 personas a las que se les preguntó ''

Ahora bien, si suponemos que la probabilidad de que el nuevo producto tenga éxito se mantiene constante \((p=0.85)\) y además suponemos que hay independencia entre cada una de las personas al azar a las que se les preguntó ⇒ Podemos modelar a \(X\) como una variable aleatoria Binomial. Esto se escribe :

\(X\) ~ \(Bi(n,p)\) en donde \(''n''\) es el número de personas entrevistadas y \(''p''\) es la probabilidad de éxito (una persona adquiriendo el producto) en cada caso.

Utilizando los datos ⇒ \(X\) ~ \(Bi(10,0.85)\)

La función de probabilidad de la variable aleatoria binomial es :

\(p_{X}(x)=P(X=x)=\left(\begin{array}{c}n&x\end{array}\right)p^{x}(1-p)^{n-x}\)    con \(x=0,1,2,...,n\)

Si reemplazamos los datos de la pregunta en la función de probabilidad obtenemos :

\(P(X=x)=\left(\begin{array}{c}10&x\end{array}\right)(0.85)^{x}(0.15)^{10-x}\) con \(x=0,1,2,...,10\)

Nos piden la probabilidad de que por lo menos 8 personas adquieran el nuevo producto, esto es :

\(P(X\geq 8)=P(X=8)+P(X=9)+P(X=10)\)

Calculando \(P(X=8), P(X=9)\) y \(P(X=10)\) por separado y sumando, obtenemos que \(P(X\geq 8)=0.820196\)

Por definición de variable aleatoria binomial, la probabilidad de que por lo menos 8 adquieran el nuevo producto es 0.8202.

En primer lugar, debes saber que la Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso.

En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles.

Por otro lado, una variable aleatoria es una función que asocia un número real, perfectamente definido, a cada punto muestral.

Una variable aleatoria es discreta si los números a los que da lugar son números enteros.

Finalmente, una distribución binomial es una distribución de probabilidad discreta que describe el número de éxitos al realizar n experimentos independientes entre sí, acerca de una variable aleatoria.

La expresión  para calcular la distribución binomial es:

P(X=x)=( \(n\\ x\) ) pˣ qⁿ⁻ˣ

Donde:

Recordar que:

( \(n\\ x\) )= \(\frac{n!}{x!(n-x)!}\)

donde el signo de exclamación representa el símbolo de factorial, es decir el producto de todos los números enteros positivos desde 1 hasta n.

En este caso, sabes que la probabilidad de que un nuevo producto tenga éxito es de 0.85 y se eligen 10 personas al azar. Entonces se define la siguiente variable aleatoria:

X= '' Número de personas que adquirirán el nuevo producto de 10 personas a las que se les preguntó ''

Suponiendo que hay independencia entre cada una de las personas al azar a las que se les preguntó, es posible usar una variable aleatoria Binomial. Siendo n el número de personas entrevistadas (en este caso, 10 personas) y p la probabilidad de éxito (una persona adquiriendo el producto, en este caso 0.85) en cada caso, la expresión a utilizar queda expresada como:

P(X=x)=( \(10\\ x\) ) 0.85ˣ (1-0.85)¹⁰⁻ˣ

P(X=x)= \(\frac{10!}{x!(10-x)!}\) 0.85ˣ (0.15)¹⁰⁻ˣ

Se desea calcular la probabilidad de que por lo menos 8 adquieran el nuevo producto. Siendo 10 las personas elegidas al azar, puede ser que sean 8,9 o 10 las personas que adquieran un nuevo producto. Entonces la probabilidad deseada es calculada como:

\(P(X\geq 8)= P(X=8) + P(X=9) + (P=10)\)

Entonces:

\(P(X\geq 8)=\)  \(\frac{10!}{8!(10-8)!}\) 0.85⁸ (0.15)¹⁰⁻⁸ +  \(\frac{10!}{9!(10-9)!}\) 0.85⁹ (0.15)¹⁰⁻⁹ +  \(\frac{10!}{10!(10-10)!}\) 0.85¹⁰ (0.15)¹⁰⁻¹⁰

Resolviendo:

\(P(X\geq 8)=\)  \(\frac{10!}{8!2!}\) 0.85⁸ (0.15)² +  \(\frac{10!}{9!1!}\) 0.85⁹ (0.15)¹ +  \(\frac{10!}{10!0!}\) 0.85¹⁰ (0.15)⁰

\(P(X\geq 8)=\)  45×0.85⁸×(0.15)² +  10×0.85⁹×(0.15)¹ +  1×0.85¹⁰×(0.15)⁰

\(P(X\geq 8)=\)  0.2759 +  0.3474 + 0.1969

\(P(X\geq 8)=\)  0.8202

Finalmente, la probabilidad de que por lo menos 8 adquieran el nuevo producto es 0.8202.

F = Qa*K

Explanation:

The force on the dipole is expressed as the negative gradient of the potential energy.

Thus;

Force; F = -dU/dx

Now, the potential energy is given as;

U = -pE

So, dU/dx = -pdE/dx

Since F = -dU/dx

Then, F = p*dE/dx

We are given p = Qa

Then;

F = Qa(dE/dx)

We are given that dE/dx = K

Thus;

F = Qa*K

According to the question, the stress developed in the rod and the tube is 64.68 N/mm³and the extension of the rod is 1.294 mm.

Change of any kind that strains a person physically, mentally, or emotionally is regarded as stressful. Stress is the body's response to anything that requires concentration or activity. Everyone goes through periods of stress.

Diameter of rod = 25 mm

Length of rod = 400 mm

External diameter of tube = 35 mm

Inside diameter of tube = 30 mm

E for steel = 200GN/m²

E for copper = 100GN/m²

A₁ = π/4 × (25)²

A₂ = 490.87 mm²

A₂ = π/4 (35² - 30²)

A₂ = 255.25 mm²

for equilibrium -

P₁A₁ + P₂A₂

= P

= 40 × 10³

so,

P₁²/E₁ = P₂²/E₂

P₁ = P₂ × (200/100)

P₁ = 2P₂

2P₂A₂ + P₂A₂ = 40 × 10³

P₂ = 32.34 N/mm³

P₁ = 2P₂ = 64.68 N/mm³

P₁ = 64.68 N/mm³

extension of rod = (64.88 × 4000) / (2×10³)

extension of rod = 1.294 mm

Answer:

the percentage of light that gets through this combination is 9.38

Explanation:

Given the data in the question;

Let us represent the incident unpolarized light with \(I_0\).

So, the amount of light intensity passing through the first polarizer will be;

\(I_1\) = \(I_0\) / 2 ------ let this be equation 1

An the amount of light intensity passing through the second polarizer will be;

\(I_2\) = \(I_1\)cos²θ

given that; the second one has its transmission axis at 30°

so, we substitute;

\(I_2\) = \(I_1\) × cos²( 30° )

\(I_2\) = \(I_1\) × 0.75

\(I_2\) = 0.75\(I_1\)

from equation; \(I_1\) = \(I_0\) / 2

\(I_2\) = 0.75( \(I_0\) / 2 )

\(I_2\) = 0.375\(I_0\) .

Now, the amount of light intensity passing through the third polarizer will be;

\(I_3\) = \(I_2\)cos² ( 90° - 30° )

\(I_3\) = \(I_2\) × cos²( 60° )

\(I_3\) = \(I_2\)  × 0.25

we substitute

\(I_3\) = 0.375\(I_0\)  × 0.25

\(I_3\) = 0.09375\(I_0\)

∴ \(I_3\)/\(I_0\) × 100 = 0.09375 × 100

⇒ 9.38%

Therefore, the percentage of light that gets through this combination is 9.38

Answer: 150m

Explanation:

The following can be depicted from the question:

Dimensions of outer walls = 9.7m × 14.7m.

Thickness of the wall = 0.30 m

Therefore, the plinth area of the building will be:

= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)

= 10 × 15

= 150m

The plinth area will be 150m.

Given information

Dimensions of outer walls = 9.7m × 14.7m.

Thickness of the wall = 0.30 m

Plinth area of the building = (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)

Plinth area of the building = 10 × 15
