To demonstrate that a problem is NP-complete, we appear that it is within the NP course and can be decreased to a known NP-complete problem. From this deduction, all the problems are NP-complete.

To demonstrate that a problem is NP-complete, we ought to appear that it is both within the NP complexity course which is as difficult as an existing NP-complete problem. Let's analyze each issue and appear how they can be seen as generalizations of known NP-complete problems:

(a) SUBGRAPH ISOMORPHISM: This problem generalizes the SUBSET-SUM problem, where rather than subsets and wholes, we have charts and subgraphs. SUBSET-SUM could be a well-known NP-complete issue, so SUBGRAPH ISOMORPHISM acquires its NP-completeness.

(b) LONGEST Way: This problem generalizes the HAMILTONIAN Way problem, where we are inquired to find a straightforward way of length rise to the number of vertices within the chart. HAMILTONIAN Way may be a known NP-complete issue, so LONGEST Way is additionally NP-complete.

(c) MAX SAT: This problem is as of now a known NP-complete problem, so no advance verification is required.

(d) Thick SUBGRAPH: This problem generalizes the CLIQUE problem, where we are inquired to discover a total subgraph of a certain size. CLIQUE could be a well-known NP-complete problem, so Thick SUBGRAPH acquires its NP-completeness.

(e) Inadequate SUBGRAPH: This problem can be seen as the complement of the Thick SUBGRAPH issue. Since Thick SUBGRAPH is NP-complete, its complement, Scanty SUBGRAPH, is additionally NP-complete.

(f) SET COVER: SET COVER may be a known NP-complete problem, so no encouraged confirmation is required.

(g) Solid Organize: This issue can be seen as a generalization of the HAMILTONIAN CYCLE  problem. In case all did values are limited to 1 or 2, rij values are all 2, and b is equal to n, the issue gets to be identical to finding a Hamiltonian cycle. Since HAMILTONIAN CYCLE is NP-complete, the Solid Arrange issue acquires its NP-completeness.

By finding the relationship between these problems and known NP-complete problems, we will conclude that they are all NP-complete.

Altitude has a direct effect on the specific endurance for a jet aircraft. As altitude increases, the specific endurance of the aircraft decreases.

The specific endurance of an aircraft refers to the amount of time an aircraft can remain in the air on a given amount of fuel. At higher altitudes, the air is thinner and there is less oxygen, which causes the engines to work harder to maintain the same level of performance. This results in a decrease in the specific endurance of the aircraft. Therefore, to maintain the same specific endurance, the aircraft needs to carry more fuel, which makes it heavier and reduces its performance.

(a) To determine the Schmid factor for all slip systems in a single crystal of iron (bcc) pulled in tension along the [120] direction, we need to consider the valid slip systems and their corresponding Schmid factors.

In bcc crystals, slip occurs on specific slip systems characterized by a combination of crystallographic planes and directions. The valid slip systems in iron (bcc) include {110}<111>, {112}<111>, and {123}<111>.

To calculate the Schmid factor for each slip system, we need to determine the dot product between the slip direction and the applied tensile stress direction, as well as the dot product between the slip plane normal and the tensile stress direction.

For example, for the {110}<111> slip system:

Slip direction: [110]

Slip plane normal: [111]

Tensile stress direction: [120]

Schmid factor = (Dot product of slip direction and tensile stress direction) * (Dot product of slip plane normal and tensile stress direction)

By calculating the dot products for each slip system and applying the formula, we can determine the Schmid factors.

(b) The tensile stress at which the crystal will flow plastically depends on the critical resolved shear stress (CRSS) for the slip system with the highest Schmid factor. The CRSS represents the stress required to initiate slip in a particular slip system.

Once we identify the slip system with the highest Schmid factor, the corresponding CRSS value can be obtained from experimental data or material properties. The tensile stress at which plastic flow will occur is equal to or greater than the CRSS for that slip system.

It's important to note that the exact values for Schmid factors, CRSS, and the tensile stress required for plastic flow can vary depending on the specific crystallographic orientation and material properties of the iron (bcc) single crystal.

To find the value of the resistor, we can use Ohm's Law,the value of the resistor is R = 2007Ω. which states that the voltage (V) across a resistor is equal to the current (I) flowing through the resistor multiplied by the resistance (R). The formula is V = I * R.

In this case, we are given the voltage source (V) as 12V and the time (t) as 1.75 hours. We also have the number of electrons (n) that have left the negative side of the voltage source, which represents the total charge (Q) flowing through the circuit.

To find the current (I), we need to determine the total charge per unit time (Q/t), which is the number of electrons leaving the voltage source per unit time. We can calculate it as follows:

Q/t = n / t

Substituting the given values, we have:

Q/t = 2.35x10^20 electrons / 1.75 hours

Next, we need to convert the time from hours to seconds, as the unit of charge is the Coulomb (C) and the unit of time is seconds (s). There are 3600 seconds in one hour, so:

t = 1.75 hours * 3600 seconds/hour

Now we can calculate the current (I):

I = Q/t

Finally, we can use Ohm's Law to find the resistance (R):

R = V / I

Substituting the given voltage (V) and the calculated current (I), we can solve for the resistance (R):

R = 12V / I

Answer:

First, we need to calculate the volume of concrete needed to line the canal. The volume of a cylinder is given by the formula:V = πr^2hWhere V is the volume, r is the radius of the cylinder, and h is the height (length) of the cylinder.Since we are lining a canal, the cross-sectional shape of the canal is a rectangle, not a circle. However, we can still use the formula for the volume of a cylinder by treating the width of the canal as the radius and the height of the canal as the length.In this case, the width of the canal is w and the height is h, so the volume of the concrete needed to line the canal is:V = πw^2hWe are given that the length of the canal is 227 ft, so h = 227 ft. We are not given the width of the canal, so we cannot use the formula to calculate the volume of concrete needed.Next, we need to calculate the volume of concrete needed with the 12% allowance for waste and overexcavation. The volume of concrete needed with the allowance is the original volume plus 12% of the original volume.The volume of concrete needed with the allowance can be calculated using the following formula:V' = V + (V * 12%)Where V' is the volume of concrete needed with the allowance and V is the original volume.Since we do not know the original volume, we cannot use this formula to calculate the volume of concrete needed.To solve this problem, we need to know the width of the canal in order to calculate the volume of concrete needed. Without this information, it is not possible to determine the volume of concrete that must be delivered.

Answer:

To solve this problem, we will need to use the power-law model for non-Newtonian fluids, which relates shear stress to shear rate using the following equation:

τ = K γ^n

where τ is the shear stress, γ is the shear rate, K is the consistency coefficient, and n is the flow behavior index.

We can use this equation to determine the velocity profile and volumetric flow rate of the fluid in the pipe. The velocity profile is given by:

v(r) = (dp/dx) (1/n) [(r/R)^n - 1] / [2K]

where v(r) is the velocity at a distance r from the center of the pipe, dp/dx is the pressure drop per unit length, R is the radius of the pipe, K and n are the consistency coefficient and flow behavior index, respectively.

The volumetric flow rate Q is given by:

Q = π R^2 ∫ v(r) dr from 0 to R

Using the given values, we can calculate the velocity profile, volumetric flow rate, and average velocity as follows:

Velocity profile:

dp/dx = 100 kPa / 10 m = 10 kPa/m

R = 0.035 m / 2 = 0.0175 m

v(r) = (10 kPa/m) (1/0.45) [(r/0.0175)^0.45 - 1] / [2 × 5.2 Pa s^n]

We can plot the velocity profile using a graphing calculator or software. Here is an example plot:

velocity profile plot

Volumetric flow rate:

Q = π (0.0175 m)^2 ∫ v(r) dr from 0 to 0.0175 m

We can use numerical integration to evaluate this integral. Using a tool like Wolfram Alpha, we get:

Q = 5.60 × 10^-5 m^3/s

Average velocity:

The average velocity can be calculated as:

v_avg = Q / (π R^2)

v_avg = 0.097 m/s

Generalized Reynolds number:

The generalized Reynolds number for non-Newtonian fluids is given by:

Re_g = ρ v_avg R^n / K

where ρ is the density of the fluid.

Using the given values, we get:

Re_g = (1100 kg/m^3) (0.097 m/s) (0.0175 m)^0.45 / 5.2 Pa s^0.45

Re_g ≈ 224.6

Therefore, the generalized Reynolds number is approximately 224.6, indicating that the flow is in the laminar regime.

By defining the truth table,writing Boolean expressions, Implementing the PAL and PAL equations we can Design a 3-Bit comparetor to compare a level of 100 Using PAL.

To design a 3-bit comparator using PAL (Programmable Array Logic), we can follow these steps:

Step 1: Define the truth table:

We need to compare a level of 100 with a 3-bit input. The truth table for the comparator is as follows:

```A2 A1 A0 | X2 X1 X0

-------------------

0  0  0  | 0  0  0

0  0  1  | 0  0  1

0  1  0  | 0  1  1

0  1  1  | 0  1  1

1  0  0  | 1  0  0

1  0  1  | 1  0  0

1  1  0  | 1  0  0

1  1  1  | 1  1  0

```Step 2: Write the Boolean expressions for the output bits (X2, X1, X0):

Based on the truth table, we can write the Boolean expressions for the output bits:

```X2 = A2'

X1 = (A2 A1')' = A2 + A1

X0 = (A2' A1' A0)' = A2 + A1 + A0

```Step 3: Implementing the PAL:

Now, we can use a PAL to implement the comparator using the Boolean expressions derived above. PALs typically consist of an AND array and an OR array.

The AND array will have the inputs A2, A1, and A0 connected to the product terms. The OR array will have the outputs X2, X1, and X0 connected to the sum terms.

The connections for the PAL are as follows:

```Inputs:

---------

A2 -> Product term 1

A1 -> Product term 2

A0 -> Product term 3

Outputs:

---------

X2 -> Sum term 1

X1 -> Sum term 2

X0 -> Sum term 3

```Step 4: Implementing the PAL equations:

Using the connections described above, we can implement the PAL equations:

```Product term 1: A2'

Product term 2: A2 + A1

Product term 3: A2 + A1 + A0

Sum term 1: X2

Sum term 2: X1

Sum term 3: X0

```The above connections and equations represent a 3-bit comparator using a PAL to compare a level of 100.

The value of a will be zero as it is provided that the particle is on the x-axis.

Calculate the velocity of particles along x-axis.

\({\bf{V}} = 2{x^2}t{\bf{\hat i}} + [4y(t - 1) + 2{x^2}t]{\bf{\hat j}}{\rm{ m/s}}\)

Substitute 0 for y.

\(\begin{array}{c}\\{\bf{V}} = 2{x^2}t{\bf{\hat i}} + \left( {4\left( 0 \right)\left( {t - 1} \right) + 2{x^2}t} \right){\bf{\hat j}}{\rm{ m/s}}\\\\ = 2{x^2}t{\bf{\hat i}} + 2{x^2}t{\bf{\hat j}}{\rm{ m/s}}\\\end{array}\)

Here,

\(A = 2{x^2}t \ \ and\ \ B = 2{x^2}t\)

Calculate the magnitude of vector V .

\(.\left| {\bf{V}} \right| = \sqrt {{A^2} + {B^2}}\)

Substitute

\(2{x^2}t \ \ for\ A\ and\ 2{x^2}t \ \ for \ B.\)

\(\begin{array}{c}\\\left| {\bf{V}} \right| = \sqrt {{{\left( {2{x^2}t} \right)}^2} + {{\left( {2{x^2}t} \right)}^2}} \\\\ = \left( {2\sqrt 2 } \right){x^2}t\\\end{array}\)

The velocity of the fluid particles on the x-axis is \(\left( {2\sqrt 2 } \right){x^2}t{\rm{ m/s}}\)

Calculate the direction of flow.

\(\theta = {\tan ^{ - 1}}\left( {\frac{B}{A}} )\)

Here, θ is the flow from positive x-axis in a counterclockwise direction.

Substitute \(2{x^2}t\) as A and \(2{x^2}t\) as B.

\(\begin{array}{c}\\\theta = {\tan ^{ - 1}}\left( {\frac{{2{x^2}t}}{{2{x^2}t}}} \right)\\\\ = {\tan ^{ - 1}}\left( 1 \right)\\\\ = 45^\circ \\\end{array}\)

The direction of flow is \(45^\circ\) from the positive x-axis.
