A sampled signal is a representation of a continuous signal that has been converted into a digital form through sampling, quantization, and encoding. Microprocessors and microcontrollers utilize sampled signals for control systems, as contactors are not suitable for high frequencies.
The sampled signal in French is called "le signal échantillonné." When dealing with a microprocessor or microcontroller control system, they give a sampled signal to the output.
The interface between the controller and system is necessary because contactors cannot be used due to their inability to handle high frequencies (and their function with 0 stop and 24 v run). However, the sampled signal has a lot of values between 0 and 5v.
A sampled signal is a representation of a continuous signal. A sampled signal is created by converting an analog signal into a digital signal by the process of sampling. The continuous-time signal is first sampled, then quantized, and finally encoded. In general, it's the number of values taken by the signal over a specific period of time.
A microprocessor is an integrated circuit that functions as the central processing unit (CPU) of a computer system. It's also known as a computer processor. It's a device that is programmed to execute arithmetic or logical operations, which are input as raw data and then transformed into usable information through software applications.
A microcontroller, like a microprocessor, is an integrated circuit that includes a processing unit, memory, and input/output (I/O) peripherals. The distinction between a microcontroller and a microprocessor is that a microcontroller is a complete computer system on a single chip.
A contactor is an electrical device used to control a load circuit in a power system. A contactor is a switch that is controlled by a low-power circuit. When a contactor is energized, its contacts close, allowing current to flow to the load. When a contactor is de-energized, its contacts open, stopping current flow to the load.

Explanation:
Correlation identifies the relationship between two variables. In the given scenario there is strong relation between non ideal mixing. The correction factor can be between -1 to 1 depending on the intensity of the relationship and dependency. The non ideal mixing efficiency is highly dependent on the factors that govern it this means there is high intensity relation so the k is estimated to be nearly 1.
A company that produces footballs uses a proprietary mixture of ideal gases to inflate their footballs. If the temperature of 230 grams [g] of gas mixture in a 15-liter [L] tank is maintained at 465 degrees Rankine [°R] and the tank is pressurized to 135 pound-force per square inch [psi], what is the molecular weight of the gas mixture in units of grams per mole [g/mol]?
Answer:
35 g/mol
Explanation:
Convert to SI units.
465 R × 5/9 = 258.3 K
Assuming the pressure is absolute pressure:
135 psi × (101.3 kPa / 14.7 psi) = 930.3 kPa
Ideal gas law:
PV = nRT
(930.3 kPa) (15 L) = n (8.314 kPa L / mol / K) (258.3 K)
n = 6.50 mol
The molar mass is therefore:
230 g / 6.50 mol = 35.4 g/mol
Rounded to two significant figures, the molar mass is 35 g/mol.
a c-section specimen is designed to tolerate a stress-concentration factor for 1.75. calculate the allowable normal strength in the c-section if the material used to make the section has a yield strength of 84 kpsi.
The allowable normal strength in the c-section is 48000 pounds per square inch.
The allowable stress depends on both the factor of safety imposed on the object and the yield strength or stress at which an object will be permanently damaged. To calculate the allowable normal strength we can divide the yield strength by the factor of safety.
To determine the allowable normal strength output we can use this equation below:
The allowable normal strength = The number yield strength : A stress-concentration factor
The number yield strength is 84 kpsi.
Then convert kpsi to psi : 84 kpsi = 84000 psi
A stress-concentration factor is 1.75
The formula to find allowable normal strength output is:
84000 psi : 1.75 = 48000

A driver is traveling at 90 km/h down a 3% grade on good, wet pavement. An accident
investigation team noted that braking skid marks started 75m before a parked car was
hit at an estimated 45 km/h. Ignoring air resistance, calculate the theoretical friction
coefficient.
Answer:
0.35
Explanation:
We resolve the component of the weight of the car along and perpendicular to the grade. We have mgsinФ and mgcosФ where Ф = angle of grade.
Now, the frictional force f = μN = μmgcosФ where μ = coefficient of friction
So, the net force along the grade is F = mgsinФ - μmgcosФ.
The work done by this force moving a distance, d along the grade is
W = (mgsinФ - μmgcosФ)d
This work equals the change in kinetic energy of the car. So ΔK = 1/2m(v₂² - v₁²) = W = (mgsinФ - μmgcosФ)d
1/2m(v₂² - v₁²) = (mgsinФ - μmgcosФ)d
1/2(v₂² - v₁²) = (gsinФ - μgcosФ)d
(v₂² - v₁²)/2d = (gsinФ - μgcosФ)
dividing through by gcosФ, we have
(v₂² - v₁²)/2dgcosФ = (gsinФ/gcosФ) - μgcosФ/gcosФ
(v₂² - v₁²)/2dgcosФ = tanФ - μ
μ = tanФ - (v₂² - v₁²)/2dgcosФ
given that tanФ = 3% = 3/100 and 1 + tan²Ф = 1/cos²Ф, cosФ = 1/(√1 + tan²Ф) = 1/(√1 + (3/100)²) = 1/(√1 + (9/10000)) = 1/(√10000 + 9/10000) = 1/√(10009/10000) = 100/√10009 = 100/100.05 = 0.9995.
Also, given that v₁ = 90 km/h = 90 × 1000/3600 m/s = 25 m/s and v₂ = 45 km/h = 45 × 1000/3600 m/s = 12.5 m/s, d = 75 m and g = 9.8 m/s².
So, substituting the values of the variables into the equation, we have
μ = tanФ - (v₂² - v₁²)/2dgcosФ
μ = 3/100 - ((12.5 m/s)² - (25 m/s)²)/(2 × 75 m × 9.8 m/s² × 0.9995)
μ = 3/100 - ((156.25 m/s)² - (625 m/s)²)/1,469.265 m²/s²
μ = 3/100 - (-468.75 m²/s²)/1,469.265 m²/s²
μ = 3/100 + 468.75 m²/s²/1,469.265 m²/s²
μ = 0.03 + 0.32
μ = 0.35
So, theoretical friction coefficient is 0.35

Consider the following Moore’s law growth pattern (since 1980) for the number of transistors inside a particular commercial microprocessor: N = 1920 x 10 0.1637(Y – 1980) where Y is the year and N is the number of transistors. Assuming sustained Moore’s law growth, what will be the number of transistors in a microprocessor in year 2025? Using the same expression, calculate how many years it will take for the transistor count to increase by 100x
Answer:
No. of transistors = \($4.1524 \times 10^{10}$\) transistors
Explanation:
Given that:
N = \($1920 \times 10^{0.163(Y-1980)}$\)
Y = 2025
N = \($1920 \times 10^{0.163(2025-1980)}$\)
N = \($4.1524 \times 10^{10}$\) transistors
Now at Y = 1980
Number of transistors N = 1920
Therefore,
\($1000 = 10^{0.163(Y-1980)}$\)
\($\log_{10} 1000=0.163(Y-1980)$\)
\($\frac{3}{0.163}=Y-1980$\)
18 ≅ 18.4 = Y - 1980
Y = 1980 + 18
= 1998
So, to increase multiples of 1000 transistors. it takes 18 years.

La probabilidad de que un nuevo producto tenga éxito es de 0.85. Si se eligen 10 personas al azar y se les pregunta si comprarían el nuevo producto, ¿cuál es la probabilidad de que por lo menos 8 adquieran el nuevo producto?
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:
n = Número de ensayos/experimentos x = Número de éxitos p = Probabilidad de éxito q = Probabilidad de fracaso (1-p)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.

3. A particle is projected to the right from the position S = 0, when an initial velocity of 8 m/s. If the acceleration of the particle is defined by the relation a = -0.5 v3/2, where a in m/s2 and v in m/s. Determine a) the distance the particle will have traveled when its velocity is 5 m/s b) the time when v = 1m/s c) the time require for the particle to travel 8m
Answer:
a) 3.5 m
b) 14 secs
c) 1.4 secs
Explanation:
a) Determine the distance the particle will travel
given velocity ( final velocity ) = 5 m/s
v^2 = u^2 + 2as
s = ( v^2 - u^2 ) / 2a
= ( 5^2 - 8^2 ) / 2 ( -0.5 * 5^3/2 )
= 3.5 m
b) Determine the time when v = 1m/s
V = u + at
1 = 8 + ( -0.5 * 1^3/2 ) * t
∴ t = 14 secs
c) Determine the time required for particle to travel 8 m
we will employ both equations above
V^2 = u^2 + 2as
s = 8 m , V = unknown , u = 8 m/s back to equation
V^2 = 8^2 + 2 ( - 1/2 * V^3/2 ) * 8
∴ V^2 + 8V^3/2 - 64 = 0
resolving the above equation
V = 3.478 m/s
now using the second equation
V = u + at
3.478 = 8 + ( - 1/2 * 3.478^3/2 ) * t
hence : t = 1.4 secs
What signal propagation phenomena causes the diffusion, or the reflection in multiple different directions, of a signal?
In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.
Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.
Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.

explain how the observation fact-finding technique works, including the hawthorne effect.
The observation fact-finding technique involves observing people in their natural environment without interfering. The Hawthorne effect is an unintended consequence where individuals being observed change their behavior due to the awareness of being observed.
The observation fact-finding technique is a research method that involves observing individuals in their natural environment without any interference. It provides valuable insights into behavior patterns, environmental interactions, and the influence of environmental factors on human behavior. This technique is widely used in various disciplines such as sociology, anthropology, psychology, and organizational behavior.
One important concept related to the observation technique is the Hawthorne effect. The Hawthorne effect refers to the unintended change in behavior that occurs when individuals being observed improve or alter their performance in response to being observed or knowing that they are being observed. The presence of an observer can lead participants to modify their behavior, not because of any external changes in their environment or situation, but solely due to the awareness of being observed.
It is crucial to recognize the Hawthorne effect when collecting data through observation because it can introduce bias into the observational data. Participants may unconsciously modify their behavior, leading to inaccurate or skewed results. Researchers should be aware of this effect and take it into consideration while interpreting the data collected through observation.
In conclusion, the observation fact-finding technique is a valuable research method for understanding human behavior patterns. However, it is important to be aware of the Hawthorne effect and its potential impact on the observed data.

you want to take apart a couple of brass parts held together by steel screws, but the screws are stuck. what should you do?
When you want to remove a stuck screw, there are some things you can try: you should be cautious when working with metals because they can quickly corrode so, to remove the screw, you should use the right equipment and tools.
The following are some of the approaches you can use to remove the stuck screw: Using a rubber band: A rubber band can be wrapped over the screw head to get a good grip, then try unscrewing the screw while applying pressure in a counterclockwise direction with your screwdriver.Using heat: Heat the area surrounding the screw with a hairdryer or heat gun if possible, being careful not to harm the surrounding area. A heat gun is best because it produces a lot of heat. If the screw is rusted, heating it causes it to expand and break the bond that is keeping it locked. After it cools, the screw can be loosened with a screwdriver.
Try penetrating oil: WD-40 or Liquid Wrench can be used to remove the screw. Spray the penetrant around the screw head and allow it to sit for 30-60 minutes before attempting to unscrew it. The oil will break down any corrosion and loosen the bond between the screw and its surrounding area.Using pliers or vice-grips: If the screw head is protruding a bit, you might be able to grip it with a pair of pliers and unscrew it by turning it counterclockwise.

A manufacturer suffers a system breach. An engineer intends a live acquisition but fails to complete it. The engineer may be stopped because "the tools really aren't preinstalled or running."
What is termed as the live acquisition?A "live" acquisition is one in which data is retrieved directly from a digital device via its normal interface, such as turning on a computer but also running programs from the operating system.
This carries some risk because data is probable to be altered. As disk drive capacities boost to the point where they become impractical to 'image,' and technology including such 'cloud computing' implies that you cannot even obtain the hardware in many cases, this process is rapidly has become the more common approach.However, there are some advantages to live acquisition, such as the possibility of recording the contents of RAM.

The systems breach in a manufacturer's system containing valuable data was prevented by an engineer planning a live acquisition due to several reasons. One reason could be the system's encryption and firewall that protected it from any unauthorized access.
Another reason could be the lack of information about the system's architecture, making it impossible to find a loophole or backdoor for a live acquisition. The engineer might also have been prevented from executing the plan because of legal barriers, such as search and seizure laws, which prohibit them from accessing the data without proper authorization. The manufacturer might have also hired professional security experts to secure the system, which made it difficult to access it. The engineer could have also faced hardware or software failures when attempting to access the data, which is a common issue when trying to obtain live acquisition of a system. In conclusion, the engineer could not execute the plan due to various technical, legal, and physical barriers that prevented them from accessing the valuable data.

a student set up the circuit shown for her electronics class. assuming e m f = 8.70 v and r = 5.00 ω, find the following quantities.
We found that the current flowing through the circuit is 1.74 amperes, the voltage drop across the resistor is 8.70 volts, and the power dissipated by the resistor is 15.14 watts.
To start, we have the circuit shown with an EMF (electromotive force) of 8.70 volts and a resistance (R) of 5.00 ohms. We need to find the following quantities: Current (I) flowing through the circuit Voltage (V) drop across the resisto Power (P) dissipated by the resistor.
To find the current (I), we can use Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. So, we have: I = V/R where V is the voltage (EMF) and R is the resistance. Plugging in the values we have, we get:
I = 8.70/5.00 = 1.74 amperes.

sin x +√3 coax= √2
Answer:
The two values of x are 2n*pi + pi/12 and 2n*pi -5pi/12
Explanation:
The given equation is
Sin x +√3 Cosx= √2
Upon dividing the equation by 2 we get
\(\frac{1}{2}Sinx + \frac{\sqrt{3} }{2}Cosx = \frac{\sqrt{2} }{2}\)
Sin(\(\frac{pi}{6}\))*Sinx + Cos(\(\frac{pi}{6}\))*Cosx = \(\frac{1}{\sqrt{2} }\)
This makes the formula of
CosACosB + SinASinB = Cos(A-B)
Cos(x-\(\frac{pi}{6}\)) = \(\frac{1}{\sqrt{2} }\)
cos(x- pi/6) = cos(pi/4)
upon writing the general equation we get
x-pi/6 = 2n*pi ± pi/4
x = 2n*pi ± pi/4 -pi/6
so we will have two solutions
x = 2n*pi + pi/4 -pi/6
= 2n*pi + pi/12
and
x = 2n*pi - pi/4 -pi/6
= 2n*pi -5pi/12
Therefore the two values of x are 2n*pi + pi/12 and 2n*pi -5pi/12.
Compare the magnitude of the dynamic viscosity and kinematic viscosity of air,water and mercury at 1 atm and 20 degrees celsius
Dynamic viscosity is greater than kinematic viscosity for air, water, and mercury at 1 atm and 20 degrees Celsius, due to their varying densities and fluid properties.
What is the relationship between dynamic viscosity and kinematic viscosity for air?Dynamic viscosity (μ) is the measure of a fluid's internal resistance to flow, while kinematic viscosity (ν) is the ratio of dynamic viscosity to density.
At 1 atm and 20 degrees Celsius, the dynamic viscosity of air is the smallest at around 1.8 x 10^-5 Pa·s, followed by water at around 8.9 x 10^-4 Pa·s, and then mercury at around 1.55 x 10^-3 Pa·s.
However, the kinematic viscosity of air is much larger than water and mercury due to its low density, at around 1.5 x 10^-5 m^2/s compared to water at around 1.0 x 10^-6 m^2/s and mercury at around 1.1 x 10^-6 m^2/s.
