a stack s is full with the structure: top 10 -1 3 bottom 17 is it possible to access value 17 in o(1) time.

Answers

Answer 1

The given statement of the stack is true.

What is stack?

A stack is an abstract data type which serves as a collection of elements, with two major operations: Push, which adds an element to the collection, as well as Pop, which removes the most recently added piece that has not yet been removed. A peek operation can also return the value of the most recently added element without altering the stack. The term "stack" refers to a collection of physical goods placed on top of one another, such as a stack of dishes.

Dear student, As we all know, in stack, we use top, which is a stack index.

In push operation top++ (post increment)

In pop operation --top ( pre decrement)

So, by referring to the aforementioned, we can now answer your question.

We want to get to the bottom element, which we can do by utilising the index value.

So, time complexity will be O(1).

Hence option is true.

If 1=10 åxtảy+12ảz A/m and H2=H2xấx-5ãy+4ảz A/m, determine: |(25 points each] (a) H2x (b) The surface current density Ř on the interface

Answers

(a) H2x = 3 A/m(b) Ř = 3π x 10^(-6) A/m. are the results for the given material which has its yz plane serve as an interface between region 1 and region 2.

Given:

Region 1 is located x > 0 with material whose μ = μo and Region 2 is located x < 0 with material whose μ = 240.1 = 10 åxtảy + 12ảz A/mH2 = H2xấx - 5ãy + 4ảz A/m

To Find:

We need to find

(a) H2x

(b) The surface current density Ř on the interface.

(a) H2xWe know,H = B/μFor region 1,μ = μo

Hence, H1 = B/μo........(1)

'For region 2, μ = 240

Hence, H2 = B/240........(2)Given, H2x = -5A/m

From equations (1) and (2),

B = μo H1 = 10 x 10^(-6) x (10 åxtảy + 12ảz) Wbm^(-2)

B = 10^(-5) (10 åxtảy + 12ảz) T

For region 2,B = 240 H2 = 240 x (-5) x 10^(-7) x ẤxB = -0.012T

From equation (2),

Hence, H1x = H2x + M(x)

Now, B = μH= μ(x) H = μoH1 for x > 0 and B = μH= 240 H2 for x < 0

Now, M(x) = Ř(x)/2and Ř(x) = M(x) x 2

Since, the two media are identical, we can apply the boundary condition given by,

H1n1 - H2n2 = Ks

Thus, H1x = H2x + M(x)

On the interface, x = 0,H1x = H2x

Hence, H2x = H1x - M(x)

Putting the values, we get H2x = 3A/m

(b) Surface current density, R

We know, Ř = Kt x H1n1

Using the above equation, we can determine the surface current density Ř.

Now, we know that H1x = H2x + M(x)

Thus, H1n1 = H1x and H2n2 = H2x

So, H1n1 - H2n2 = Ks => Ks = M(0) = 0

Hence, Kt = μoWe know that H1n1 = H1

xHence, Ř = Kt x H1n1= μoH1x

Now, we know

H1x = 3 A/m

μo = 4π x 10^(-7) H/m

Thus, Ř = μoH1x = 3 x 4π x 10^(-7) = 3π x 10^(-6) A/m.

Set up the following characteristic equations in the form suited to Evanss root-locus method. Give L(s),
Set up the following characteristic equations in the form suited to Evanss root-locus method. Give L(s),

Answer: a(s) is of degree n and b(s) is of degree n-1.

a)Characteristic equation in form suitable for Evans's root-locus method is given by a(s) + b(s)K = 0, where a(s) and b(s) are polynomials of s with real coefficients. Now, given equation can be represented as: s + (1/τ) = 0 => s + (1/τ) = 0s + (1/τ)K = 0=> K = -τs/τ + 0Thus, L(s) = s, a(s) = 1, b(s) = 1 and K = -τ.

b)The characteristic equation is given by:s^2 + cs + c + 1 = 0For the root-locus method, we have to write the characteristic equation in the form a(s) + b(s)K = 0. Since the degree of a(s) is 2, we select K such that the degree of b(s) is also 2, and so b(s) will be monic.s^2 + cs + c + 1 = 0=> (s + c/2)^2 + 1/4 - c^2/4 + c = 0=> s^2 + (2c)s + (1 + c - c^2/4) = 0Now, taking a(s) = s^2 + (2c)s + (1 + c - c^2/4) and b(s) = 1 with K = -1/c^2, we have:a(s) + b(s)K = s^2 + (2c)s + (1 + c - c^2/4) - 1/c^2 = 0

c) The characteristic equation is given by:(s + c)3 + A(Ts + 1) = 0

i. versus parameter A:s = -c is a repeated root of multiplicity 3 when A = 0For s = -c, the characteristic equation becomes:-A(Tc + 1) = 0If A = 0, the characteristic equation will be (s + c)^3 = 0 and will have a repeated root at s = -c with a multiplicity of 3.

ii. versus parameter T:s = -c is a repeated root of multiplicity 3 when T = 0.For s = -c, the characteristic equation becomes:3c^2s + A = 0If A = 0, the characteristic equation will be (s + c)^3 = 0 and will have a repeated root at s = -c with a multiplicity of 3.

iii. versus the parameter c:We cannot draw the root locus of (s + c)3 + A(Ts + 1) = 0 with respect to the parameter c because there is no c term in the characteristic equation; it only contains c cubed.

d) The characteristic equation is given by:1 + (kp + k1/s + kDs/Ts + 1)G(s) = 0Assuming G(s) = Ac(s)/d(s), where c(s) and d(s) are monic polynomials with the degree of d(s) greater than that of c(s), the characteristic equation becomes:

d(s) + kp d(s) + k1 d(s)/s + kDs c(s)/T = 0.

Thus, a(s) = d(s) + k1 d(s)/s and b(s) = kDc(s)/T + kp d(s) with K = -1.

Therefore, a(s) is of degree n and b(s) is of degree n-1.

A 75-hp motor that has an efficiency of 91.0% is worn-out and is replaced by a motor that has a high efficiency 75-hp motor that has an efficiency of 95.4%. Determine the reduction in heat gain in the room due to higher efficiency under full-load conditions (load factor

Answers

Answer:

the reduction in the heat gain is 2.8358 kW

Given that;

Shaft outpower of a motor  = 75 hp = ( 75 × 746 ) = 55950 W

Efficiency of motor  = 91.0% = 0.91

High Efficiency of the motor  = 95.4% = 0.954

now, we know that, efficiency of motor is defined as;  =  /

where   is the electric input given to the motor

so

=  /

we substitute

= 55950 W / 0.91

= 61483.5 W

= 61.4835 kW

now, the electric input given to the motor due to increased efficiency will be;

=  /

we substitute

= 55950 W / 0.954

= 58647.79 W

= 58.6477 kW

so the reduction of the heat gain of the room due to higher efficiency will be;

Q =  -

we substitute

Q = 61.4835 kW - 58.6477 kW

Q = 2.8358 kW

Therefore, the reduction in the heat gain is 2.8358 kW

Refrigerant leaving the metering device going to the evaporator should be________________

Answers

Refrigerant leaving the metering device and entering the evaporator should be in a **low-pressure liquid state**.

The metering device in a refrigeration system, such as a thermostatic expansion valve (TXV) or an orifice tube, plays a crucial role in controlling the flow and pressure of the refrigerant. Its primary function is to regulate the refrigerant flow rate into the evaporator, ensuring proper cooling and heat absorption.

When the refrigerant passes through the metering device, it undergoes a pressure drop, transitioning from a high-pressure liquid state to a low-pressure liquid state. This pressure reduction allows the refrigerant to expand and evaporate inside the evaporator coil, absorbing heat from the surrounding air or space.

It is important for the refrigerant leaving the metering device and entering the evaporator to be in a low-pressure liquid state rather than a vapor or high-pressure liquid. A low-pressure liquid state ensures efficient heat transfer within the evaporator, as the liquid refrigerant can absorb heat effectively from the system's surroundings.

If the refrigerant were to enter the evaporator as a vapor or a high-pressure liquid, it could lead to several issues. Vapor entering the evaporator would hinder the heat transfer process, as it would need to undergo additional phase change from vapor to liquid before effectively absorbing heat. On the other hand, a high-pressure liquid entering the evaporator could result in reduced evaporator efficiency and potential damage to the system components.

Therefore, maintaining the refrigerant in a low-pressure liquid state as it leaves the metering device and enters the evaporator is essential for optimal refrigeration system performance and efficient heat transfer.

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3

Answers

Please refer to the uploaded Manning's roughness modifier PDF file to determine the appropriate roughness coefficient (n) for the given conditions and use it in the Manning's equation to calculate the flow rate (Q).

To determine the flow rate in the unlined open channel, we can use Manning's equation:

Q = (1.49 / n) * A * R^(2/3) * S^(1/2)

where:

Q is the flow rate,

n is the Manning's roughness coefficient,

A is the cross-sectional area of flow,

R is the hydraulic radius, and

S is the slope of the channel.

Given:

Width (B) = 12 ft

Depth (y) = 3 ft

Side slopes (h:v) = 4:1

Slope (S) = 0.001 ft/ft

First, let's calculate the cross-sectional area of flow (A):

A = B * y + (h * y^2) / 2

= 12 ft * 3 ft + (4 * 3 ft^2) / 2

= 36 ft^2 + 18 ft^2

= 54 ft^2

Next, let's calculate the hydraulic radius (R):

R = A / P

= A / (B + 2y)

= 54 ft^2 / (12 ft + 2 * 3 ft)

= 54 ft^2 / 18 ft

= 3 ft

Now, we need to determine the Manning's roughness coefficient (n) using the provided Manning's roughness modifier table (PDF file). Please refer to the uploaded file to find the appropriate roughness coefficient for the given conditions.

At a eutectic point, two solid phases and a liquid phase are in equilibrium. In other words, three phases are present when the system is at equilibrium. Let's go into more detail about what a eutectic point is and why it's important on a phase diagram.A eutectic point is the lowest temperature at which a eutectic mixture melts. A eutectic mixture is a combination of two or more components that, when melted, results in a homogeneous liquid that solidifies into two or more solid phases.

In the case of a binary mixture, a eutectic mixture contains two components in specific proportions that produce a eutectic reaction.The eutectic point on a binary temperature-composition phase diagram is located at the intersection of the two solidus curves (which represent the temperatures at which solidification of one component occurs) and the liquidus curve (which represents the temperature at which melting of the solid occurs). At the eutectic point, the proportions of the two components are such that the solid phases are in equilibrium with the liquid phase, resulting in the formation of two solid phases and a liquid phase.

What is the R equivalent data type to a Python float is numeric. The main answer to this question is "numeric". The data type that corresponds to the Python float data type in R is numeric. In R, we use numeric to represent the data type of decimal values or numbers with a fractional part. For instance, numeric data type can be used to represent the height of a person or the weight of a material.

Numeric data type can be both a floating-point or integer value.To create new columns that are functions of existing ones, we use the mutate function. The main answer to this question is "mutate". In R programming, the mutate function is used to add new variables to the existing data frame or modify the existing variable by applying a function to it.To view the Sacramento dataset by price, from highest to lowest, the order function is missing. The order function is used to arrange the rows of a data frame in ascending or descending order. Here's the code:

`arrange(sacramento_real_estate_transactions, desc(price))`.The following code will cause x and y to appear in the dataset False. The answer to this question is False. The "everything()" function is used to select all the columns in a data frame except those that have been explicitly excluded.The character that is missing from the following code is `%>%`. The main answer to this question is "%>%". The pipe operator `%>%` is used to connect multiple operations together so that each output is passed to the next operation as input. Here's the corrected code: `mutate(flights_sml, gain = dep_delay - arr_delay, hours = air_time / 60, gain_per_hour = gain / hours) %>% select(gain_per_hour)`.

The option that identifies the type of engineer described in the following scenario is a structural stability. So, option B is accurate.

What is a skyscraper?

A skyscraper is a tall building that has multiple floors, and it is often found in a city. In the early days, tall buildings were constructed with steel frames and are now typically made of reinforced concrete or steel. The main aim of a skyscraper is to give a lot of usable space on a small amount of land.

The building design described in the scenario is likely a "skyscraper" or a tall building in Richmond, VA. The engineer, Sean, relies heavily on geometry in his research of building design, which suggests that the design of the building involves complex geometric calculations and considerations. Skyscrapers are typically characterized by their height and often require advanced engineering techniques and calculations, including geometry, to ensure structural stability and safety.

a centrifugal pump operating at 1000 rpm is delivering 80 gpm of water at 150 psig and requires 8 hp of shaft power at the best efficieny point determine the flow rate discharge pressure required shaft power and efficiency

Answers

Answer:

Flow rate = 118.8 gpm, discharge pressure= 331.5 psig, shaft power = 26.3 hp and Efficiency = 87.5%.

Explanation:

Without mincing words, let us dive straight into the solution to the question above. So, the following parameters or data are given in the question above:

gpm = 80 gpm, shaft power = 8hp, and the pressure of  150 psig.

The flow rate =[ 80 × 1500] ÷ 100g = 118.9 gpm.

Hence, the discharge pressure = 150 × [ 1500/100]² = 331.5 psig.

Also, the required shaft power = 8 × [ 1500/100]³ = 26.3 hp.

The last part that is the efficiency can be calculated as given below:

Efficiency = [ 80 × 0.00223 × 144 × 150 ] ÷ [550 × 8 ] = 0.875 = 87.5%.
