The voltage through a resistor with current i(t) in the s-domain is simply Ri(s), where R is the resistance value of the resistor. In the s-domain, the relationship between voltage and current through a resistor can be expressed using Ohm's law as V(s) = I(s)R.

Therefore, the voltage across a resistor in the s-domain is proportional to the current through it, with the proportionality constant being the resistance value. It's important to note that this relationship only holds true for resistive elements in linear circuits. Non-linear circuit elements such as diodes and transistors have much more complex voltage-current relationships that cannot be described using a simple linear equation.

Answer:

1) probability that the average concentration of pollutants in the stream on a given day will exceed 85 mg/l is 0.0018

2) probability that a critical level of 95 mg/l will only be exceeded at the most one day in a given week (seven days) is 0.9993

Explanation:

Given the data in the question;

mean μ = 50 mg/l

standard deviation σ = 12 mg/l

we know that; x-score = x-μ /  σ

1) probability that the average concentration of pollutants in the stream on a given day will exceed 85 mg/l

p( x > 85 ) = P( Z > 85-50 / 12 )

= P( Z > 35/12 )

= P( Z > 2.9166)

= P( Z > 2.92)

= 1 - P( Z > 2.92)

from z-score table; P( Z > 2.92) = 0.9982

= 1 - 0.9982

p( x > 85 ) = 0.0018

Therefore, probability that the average concentration of pollutants in the stream on a given day will exceed 85 mg/l is 0.0018

2) probability that a critical level of 95 mg/l will only be exceeded at the most one day in a given week (seven days). Assume that the pollutant concentrations between days are statistically independent.

p( x > 95 ) = p( Z > 95-50 / 12 )

= p( Z > 45 / 12 )

= p( Z > 3.75 )

= 1 - p( Z > 3.75 )

from z-score table; p( Z > 3.75 ) = 0.9999

= 1 - 0.9999

= 0.0001

Now; p = 0.0001 and n = ( week) = 7

x = number of days × exceeds 99 mg/l

x ¬ Binomial ( n =7    p = 0.0001 )

p(x ≤ 1) = p(x=0) + (p=1)

= ¹∑\(_{x=0}\)   \(^7C_x ( 0.0001)^x\) \((0.9999)^{7-x}\)

= \(^7C_0 ( 0.0001)^0\) \((0.9999)^{7-0}\)

= 7!/(0!(7-0)!) \(( 0.0001)^0\) \((0.9999)^{7-0}\)

= (1) ( 1 ) ( 0.9993 )

= 0.9993

Therefore,  probability that a critical level of 95 mg/l will only be exceeded at the most one day in a given week (seven days) is 0.9993

steam tables or thermodynamic software and verify the accuracy of the specific enthalpy and internal energy values for water vapor, as well as the properties of air, to ensure precise calculations.

In the given problem, two separate scenarios are described. Let's address each scenario individually.

Scenario 1: Water vapor cooling at constant volume

Starting with water vapor at 2.0 MPa and 300 °C, it is cooled at constant volume until the temperature drops to 150 °C. At the end of the process, we need to find the dryness fraction and the specific internal energy of the saturated liquid-vapor mixture.

To determine the dryness fraction, we need to calculate the quality (x) of the mixture, which represents the mass fraction of vapor present. The dryness fraction can be calculated using the equation:

x = (h - hf) / (hg - hf),

where h is the specific enthalpy of the mixture, hf is the specific enthalpy of the saturated liquid at the final temperature, and hg is the specific enthalpy of the saturated vapor at the final temperature.

The specific internal energy (u) of the saturated liquid-vapor mixture can be determined using the equation:

u = (x * u g) + ((1 - x) * u f),

where ug is the specific internal energy of the saturated vapor at the final temperature, and uf is the specific internal energy of the saturated liquid at the final temperature.

Scenario 2: Compressed air in a cylindrical tank

Given a compressed air pressure of 400 kPa, a tank diameter of 0.3 m, a height of 1.5 m, and the specific gas constant (R) for air as 0.287 kJ/kg·K, we need to find the mass and specific weight of the compressed air.

To determine the mass of the compressed air, we can use the ideal gas law:

PV = mRT,

where P is the pressure, V is the volume of the tank, m is the mass, R is the specific gas constant, and T is the temperature.

The specific weight (γ) can be calculated by dividing the weight (W) of the air by the volume (V) of the tank:

γ = W / V.

By substituting the known values into the equations and performing the necessary calculations, the mass and specific weight of the compressed air can be determined.

The condition that DC(s) must satisfy for the system to track a ramp reference input with constant steady-state error is DC(0) = 1.

To achieve constant steady-state error when tracking a ramp reference input, the condition that DC(s) must satisfy is that its DC gain (evaluated at s = 0) is nonzero.

In other words, DC(0) should not equal zero.

This condition ensures that the system has a non-zero steady-state response to a ramp input, allowing it to accurately track the desired slope without accumulating an error over time.

A non-zero DC gain implies that there is a non-zero steady-state output even for a constant input, which is necessary to achieve constant steady-state error when the input is a ramp signal.

If a four-speed transmission car averages 30 miles per gallon and gasoline costs $4.00 per gallon, the maximum amount that should be paid for a fuel-efficient six-speed transmission is $453.

We are given the following:

Total Fuel Cost when using traditional transmission = Miles Per Year / Miles Per Gallon x Per Gallon Cost

= Miles/year

= 120000 / 10 = 12,000 miles

Hence the Total Fuel Cost = 12000/30 x 4

= $1,600

With 6 speed , miles per gallon = 30 x (1+ 0.04) = 30* 1.04 = 31.20 MPG

Hence the reviewed Cost = 12000 / 31.20 * 4 = $1,538.50

This means that  Yearly Savings in cost = 1,600 - 1538.50

= $61.50 per year

Hence, every year we save $61.50

Therefore, the maximum amount that will be paid extra is the present value of all the savings where n =10 and i = 6%

So, PVIFA (n=10 , i=6%) = 7.3601

The correct option for the implication of low variety is B) Flexibility needed. Variety refers to the number of different products, services, or activities that an organization offers. High variety means that a company offers a wide variety of products or services, while low variety means that a company provides a limited range of products or services.

One of the implications of low variety is that customers have limited options. They are restricted to purchasing only those goods and services that the company offers, which may not match their requirements or preferences. This may lead to losing customers to rivals who offer a greater variety of goods and services.

In the case of low variety, it is critical to have the required flexibility. Customers may ask for certain specific goods or services that are not provided by the company. To meet customer requirements, the company should be adaptable and able to rapidly respond to customer requests by expanding its product line. As a result, low variety necessitates the need for flexibility.

The other given options are not valid. Low unit cost is not related to low variety. Unit cost may be affected by economies of scale and other factors, but it is not directly related to variety. High complexity is not related to low variety as well. As the range of goods and services offered by the company increases, the complexity of the company's operations and management also increases. Matching customers' specific needs is partially correct because the company cannot match customer specific needs in low variety.

The capacity of the pump is 7.82 gallons per minute (GPM).

To determine the capacity of the pump, we can use the formula:

Q = (n * Vd * VE) / 231

Where Q is the flow rate, n is the number of strokes per minute, Vd is the volume displaced per stroke, VE is the volumetric efficiency, and 231 is a conversion factor from cubic inches to gallons.

We know that:

n = 170 strokes/minute

VE = 0.89

To calculate the volume displaced per stroke, we can use the formula:

Vd = π/4 * D^2 * S

Where D is the diameter of the cylinder and S is the stroke length.

So we have

D = 6 inches

S = 14 inches

Vd = (π/4) * (6 inches)^2 * 14 inches = 301.57 inches^3

Now we can substitute these values into the first formula

However, in most cases, the engine should be cold (or at most warm) before adding coolant to the radiator. Never attempt to add coolant to the radiator while the engine temperature is high, since pressurized water may escape from the reservoir when the coolant cap is unscrewed.

Antifreeze, often known as engine coolant, is a colored liquid combined with water that helps control your engine at high temperatures. To maintain a consistent operating temperature, coolant is circulated throughout the engine block when the temperature outside fluctuates from hot to cold.

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.
