Consider a transmission line of length, L, and characteristic impedance of 50 ohms. What is the smallest value of L(in wavelengths) such that a short-circuited transmission line appears to be an open circuit to the generator?

Answers

Answer 1

So, the minimum length (in wavelengths) for which the short-circuited line seems like an open line is infinity. It means that a short-circuited transmission line can never seem like an open circuit.

Consider a transmission line of length, L, and characteristic impedance of 50 ohms. What is the smallest value of L (in wavelengths) such that a short-circuited transmission line appears to be an open circuit to the generator? To determine the minimum length (in wavelengths) of a short-circuited transmission line that appears to be an open circuit to a generator, we must employ the concept of impedance matching. This occurs when the load impedance is equal to the characteristic impedance of the transmission line. It is not just a matter of length. The smallest value of L (in wavelengths) is defined as follows: When the input impedance of a transmission line is equal to its characteristic impedance, an input signal propagates down the line without reflection. This is known as a matched line. If the input impedance is zero, the line appears to be an open circuit; this is known as an open line. A short-circuited line, on the other hand, appears to have an input impedance of zero. Hence the minimum length (in wavelengths) for which the short-circuited line seems like an open line is as follows: We use λ as the wavelength here.λ = c/f Where c is the speed of light and f is the frequency of the input signal. Since we are concerned with the transmission line's electrical length, we must use the velocity factor (Vf). Vf = v/c where v is the phase velocity of the transmission line. We can compute the electrical length of the transmission line with these parameters. L/(λVf) = 0.5 So, substituting all of the values, we get; L/(λVf) = 0.5L/[(c/f)Vf] = 0.5L = λ/4VfTo be matched, the load resistance must equal the characteristic impedance of the transmission line. Zo is equal to 50 ohms in this situation, and we must match the input resistance to the output resistance. Since we have a short circuit at the line's far end, it has a resistance of zero. We must therefore find a value for Zo that equals zero. It indicates that we require an infinitely long line (not practical). Therefore, if Zo equals zero (an infinitely long line), the shortest length (in wavelengths) of the short-circuited transmission line that appears to be an open circuit to the generator is infinity. As a result, a short-circuited transmission line can never seem like an open circuit.

So, the minimum length (in wavelengths) for which the short-circuited line seems like an open line is infinity. It means that a short-circuited transmission line can never seem like an open circuit.

My birthday is coming up. Alas, I am getting old and would like to feel young again. Fortunately, I have come up with an excellent way of feeling younger: if I write my age as a number in an appropriately chosen base b, then it appears to be smaller. For instance, suppose my age in base 10 is 32. Written in base 16 it is only 20! However, I cannot choose an arbitrary base when doing this. If my age written in base b contains digits other than 0 to 9, then it will be obvious that I am cheating, which defeats the purpose. In addition, if my age written in base b is too small then it would again be obvious that I am cheating. Given my age y and a lower bound I on how small I want my age to appear, find the largest base b such that y written in base b contains only decimal digits, and is at least I when interpreted as a number in base 10. Input The input consists of a single line containing two base 10 integers y (10 ≤ y ≤ 1018-yes, I am very old) and I (10 ≤l≤y). Output Display the largest base b as described above.

The problem is asking us to find a base b, for which the age of the person can be represented as a number with decimal digits only, but when interpreted in base b, it should be greater than or equal to I. The problem can be solved using binary search technique. We can try out all bases starting from 10, and for each base, convert the given number to that base, and check if all its digits are less than or equal to 9, and the converted number is greater than or equal to I. If both conditions are satisfied, we store this base as a possible solution, and move on to the next base. We return the largest possible base among all the possible solutions. Let's write the algorithm to solve the problem.

We start by setting the left limit L to 10, and the right limit R to y. Then, we perform the following steps inside a while loop, until L < R:We set the mid value as (L + R + 1) // 2. This is done to avoid an infinite loop in cases where L and R differ by 1. For example, if L = 10 and R = 11, and we choose mid as (10 + 11) // 2 = 10, we will end up with L = mid, which will lead to an infinite loop.We convert y to base mid, using the built-in function in Python - int(y, mid). We then check if all digits in the converted number are less than or equal to 9, and the converted number is greater than or equal to I.If the above conditions are satisfied, we set L to mid, since the possible solution should lie to the right of the current base. Otherwise, we set R to mid - 1, since the possible solution should lie to the left of the current base.At the end of the while loop, we return L as the answer.

The algorithm that can be used to solve the problem is:

Initialize result to zero
Iterate through the string columnTitle
Calculate the value of each character in the string columnTitle using its ASCII code, that is, subtracting 64 from its ASCII code and multiplying the result by 26 raised to the power of the position of the character from the right in the string
Add the result of each iteration to the result initialized at the beginning
Return the result


The ASCII code of A is 65, B is 66, C is 67, ..., Z is 90. Therefore, to calculate the value of each character in the string columnTitle, we subtract 64 from its ASCII code to get a number between 1 and 26 (inclusive) that corresponds to its position in the English alphabet.For example, the ASCII code of A is 65, so 65 - 64 = 1, which is the value of A in Excel. The ASCII code of Z is 90, so 90 - 64 = 26, which is the value of Z in Excel.To calculate the value of a two-character string such as AB, we need to calculate the value of each character separately and then add them together. The value of A is 1, and the value of B is 2 * 26 = 52 (because B is the second letter of the alphabet and there are 26 letters in the alphabet). Therefore, the value of AB is 1 + 52 = 53.To calculate the value of a three-character string such as ZY, we need to calculate the value of each character separately and then add them together.

Given the system accepts nickels (5 cents), dimes (10 cents), and quarters (25 cents), we can now modify the given state diagram for the vending machine as shown below:Initially, the vending machine starts in the idle state, waiting for the user to insert coins. When a nickel is inserted, the system transitions to the accept-5 state.

In the accept-5 state, the system waits for the user to insert additional coins. If a dime is inserted, the system transitions to the accept-10 state, and if a quarter is inserted, the system transitions to the accept-25 state.

The accept-10 and accept-25 states work similarly, as they wait for the user to insert additional coins. Once the total amount of money inserted exceeds or equals the price of the item, the system moves to the dispense state and dispenses the item to the user. If the user has inserted more money than the price of the item, the system returns the change to the user before moving back to the idle state.

A pump draws water from a well through a vertical pipe 15 cm in diameter. The bomb drains through a horizontal pipe 10 cm in diameter, located 3.20 m above the water level from the well. When 35 lit/sec are pumped, the readings of the pressure gauges placed at the inlet and at the pump output are -31.4 kPa and 176.5 kPa, respectively. The discharge pressure gauge is located 1.0 m above the suction pressure gauge. Determine the power output of the pump.

Answers

The power output of the pump is 8.2 kW.

Given: Diameter of the vertical pipe (D₁) = 15 cmDiameter of the horizontal pipe (D₂) = 10 cm.

The distance between the horizontal pipe and the water level from the well (h) = 3.20 m,

Discharge pressure gauge is located at a height (H) = 1.0 mSuction pressure gauge reading = -31.4 kPaDischarge pressure gauge reading = 176.5 kPa.

To determine: Power output of the pump using the given dataWe know that the power output of the pump can be calculated using the formula:P = Q × H × ρ /  η.

Where,P = Power output of the pumpQ = Volume flow rate of waterH = Headρ = Density of waterη = Efficiency of the pump.

From Bernoulli’s equation, we can write:P₁ + 1/2 ρV₁² + ρgh₁ = P₂ + 1/2 ρV₂² + ρgh₂P₁ = Suction pressure gauge reading = -31.4 kPaP₂ = Discharge pressure gauge reading = 176.5 kPaV₁ = V₂ (volume flow rate is constant)h₁ = 0h₂ = H = 1.0 m∴ -31.4 + 1/2 ρV₁² = 176.5 + 1/2 ρV₁² + ρgH.

Now, we have V₁, volume flow rate can be determined as,Q = A₁ × V₁Where A₁ is the area of the pipe A₁ = πD₁²/4 = π × (15/100)²/4 = 0.01767 m².

Now, volume flow rate,Q = 35 L/s = 35 × 10⁻³ m³/sPower output of the pump is:P = Q × H × ρ /  η.

Where, ρ = density of water at standard conditions of temperature and pressure (STP) = 1000 kg/m³Let us put all the values in the formula and calculate,P = 35 × 1.0 × 1000 / 2 × 9.81 × (176.5 + 31.4) × 0.95P ≈ 8.17 kW or 8.2 kW (rounded off to one decimal place).

Therefore, the  answer is 8.2 kW.

 As per the given question, we have been asked to calculate the power output of the pump. We can use Bernoulli's equation to solve this problem.

Bernoulli's equation relates the pressure at any two points in a fluid, along with the velocities at those two points. We know the readings of the pressure gauges placed at the inlet and at the pump output, which are -31.4 kPa and 176.5 kPa, respectively.

The discharge pressure gauge is located 1.0 m above the suction pressure gauge.

From Bernoulli’s equation, we can write: P₁ + 1/2 ρV₁² + ρgh₁ = P₂ + 1/2 ρV₂² + ρgh₂  Here, P₁ and P₂ are the pressures at the inlet and outlet of the pump.
V₁ and V₂ are the velocities at those points. h₁ and h₂ are the heights of the pipe above some datum.  Now, we have V₁, volume flow rate can be determined as, Q = A₁ × V₁.

Using this, we can calculate the power output of the pump using the formula, P = Q × H × ρ /  η, where H is the height, ρ is the density, and η is the efficiency of the pump.  

Thus, the power output of the pump is 8.2 kW.

The function first creates an empty dictionary called `grade_count` to store the grades and their count. Next, we loop through each grade in the array of grades. For each grade, we check if it already exists in the `grade_count` dictionary. If it does not exist, we add it to the dictionary with a count of 1. If it does exist, we simply increment its count by 1. Finally, we return the `grade_count` dictionary containing the grades and their count. The data structure used is a dictionary, which provides constant time complexity for insertions and lookups.

Answers

The output of the code will be:

```

5

```

The code you provided defines a recursive function `quest8` that takes two integer references `a` and `b` as parameters.

The function compares the values of `a` and `b`. If `a` is less than `b`, it returns the value of `b`. Otherwise, it recursively calls `quest8` with `a` and `b` incremented by 1 and increments the returned value by 1.

In the `main` function, two variables `x` and `y` are declared and assigned the values 3 and 1, respectively. Then, the value of `quest8(x, y)` is printed using `cout`.

To determine the output, let's trace the execution of the code:

1. In the `main` function, `x` is 3 and `y` is 1.

2. The function `quest8` is called with `a` as a reference to `x` (3) and `b` as a reference to `y` (1).

3. Since `a` is not less than `b`, the function recursively calls `quest8` with `a` incremented by 1 (4) and `b` incremented by 1 (2).

4. In the new recursive call, `a` (4) is still not less than `b` (2), so it recursively calls `quest8` again with `a` incremented by 1 (5) and `b` incremented by 1 (3).

5. In the third recursive call, `a` (5) is now less than `b` (3), so it returns the value of `b` (3).

6. Going back to the second recursive call, it increments the returned value by 1, resulting in 4.

7. Going back to the initial call, it increments the returned value by 1, resulting in 5.

8. The value of `quest8(x, y)` is 5.

The important parameters in Genetic Algorithm (GA), Crossover Mutation Population Size are complimented by the following parameters in Harmony Search Algorithm (HSA):Pitch adjusting rateBandwidthNumber of improvisations

The complement parameters to GA's parameters are as follows:Pitch adjusting rateBandwidthNumber of improvisationsPopulation sizeCrossover and mutation are basic operations of genetic algorithm (GA). Crossover is the process of exchanging genetic material between parents to generate new offspring. Mutation is the process of modifying the genetic material in an offspring in a random manner.GA is one of the most popular optimization techniques used in engineering and science because of its ability to find optimal solutions to complex optimization problems.

Harmony search algorithm (HSA) is another optimization technique that has become increasingly popular in recent years. HSA is inspired by the process of musicians improvising in a band. HSA has been successfully applied to a wide range of optimization problems and has been shown to be very effective. The main difference between GA and HSA is that HSA uses a stochastic search algorithm while GA uses a deterministic search algorithm. In HSA, a set of parameters are tuned to find the best solution to the optimization problem. These parameters are pitch adjusting rate, bandwidth, and number of improvisations. The pitch adjusting rate is used to adjust the pitch of a note in a melody. The bandwidth is used to control the width of the search space.

A sand filter is 1 m thick and has an area of 150 m². Compute the amount of water that will be filtered in m³/s and gallons/min, if the hydraulic conductivity of the sand is 10-³m/s and the hydraulic head drop is 3 m. Show your computation.

Answers

Given that,

Thickness of sand filter (L) = 1 m

Area of the filter (A) = 150 m²Hydraulic conductivity of sand (k) = 10-³m/s

Hydraulic head drop (h) = 3 m

To calculate the water filtered by the sand filter, we use the formula of Darcy's Law which is given by, Q = kA [(h/L)]Where Q is the rate of discharge in m³/s, k is the hydraulic conductivity of sand, A is the area of the filter, h is the hydraulic head drop and L is the thickness of the sand filter.

So, substituting the values in the above formula, we get;

Q = 10^-3 x 150 x [(3/1)]m^3/sQ = 0.45 m^3/s

A sand filter is 1 m thick and has an area of 150 m². Compute the amount of water that will be filtered in m³/s and gallons/min, if the hydraulic conductivity of the sand is 10-³m/s and the hydraulic head drop is 3 m. Show your computation" is 0.45 m³/s.To calculate the gallons per minute, we multiply the rate of discharge with the conversion factor which is 15850.32. Therefore, Gallon per minute = Q x 15850.32=> 0.45 x 15850.32 = 7132.64 Gallon per minute

3 points Exercise 1: Steam at 0.6 MPa and 200 C enters an insulated nozzle with a velocity of 50 m/s. It leaves at a pressure of 0.15 MPa and a velocity of 600 m/s. Determine the final temperature if the steam is superheated in the final state and the quality if it is saturated.

Answers

Given data:

Initial pressure

P₁ = 0.6 M

PaInitial temperature

T₁ = 200 °C

Initial velocity

V₁ = 50 m/s

Final pressure

P₂ = 0.15 MPa

Final velocity

V₂ = 600 m/s

Process: It is given that the nozzle is insulated, so the process can be considered as an adiabatic process (Q = 0) and nozzle is assumed to be frictionless (W = 0).

By conservation of mass, the mass flow rate at the inlet and outlet of the nozzle remains same.

Using conservation of energy, we can write the Bernoulli’s equation as:

P₁/ρ₁ + V₁²/2 = P₂/ρ₂ + V₂²/2 …(i)

For an adiabatic process (Q = 0), we know that

P₁/ρ₁⁻ᵞ = P₂/ρ₂⁻ᵞ …(ii)

From steam tables, at P₁ = 0.6 MPa and T₁ = 200°C, h₁ = 2969.1 kJ/kg, s₁ = 6.5856 kJ/kg-K and ρ₁ = 3.146 kg/m³

Using h, P and s, we can find out the properties at the outlet of the nozzle:

a) If the steam is superheated in the final state (s > sf + x * sg), then

h₂ = h₁ + V₁²/2 - V₂²/2 …(iii)

Using h₁, V₁, V₂, we get

h₂ = 3058.68 kJ/kg

Now, we can find out the final temperature T₂ using h₂, P₂.

Using h₂ and P₂, we find out T₂ = 238.7 °Cb)

If the steam is saturated at the outlet of the nozzle (s = sf + x * sg), then

s₂ = sf + x * sg

Using s₂ = s₁ and P₂, we can determine the quality x at the outlet of the nozzle.

Using P₂, x = 0.9247

Thus, the final temperature T₂ for superheated steam is 238.7 °C and the quality for saturated steam is 0.9247 (approximately).

The validity of the sequent 1x (R(x) → Q(x)) + x (R(x) v Q(x)) cannot be proved by finding a mathematical model where the formula to the left of R(x) → Q(x) evaluates to T but the formula to the right of R(x) v Q(x) evaluates to F. We need to prove this statement, so let's first identify what it means.

The sequent 1x (R(x) → Q(x)) + x (R(x) v Q(x)) can be read as: for all x, if R(x) is true then Q(x) is true, or R(x) is true or Q(x) is true.

Now, let's say that we found a mathematical model where R(x) → Q(x) evaluates to T, but R(x) v Q(x) evaluates to F. That means that for all x, if R(x) is true then Q(x) is true, but R(x) is not true and Q(x) is not true. This is a contradiction, since it's impossible for both R(x) and Q(x) to be false when R(x) → Q(x) is true.

6. Check if the cost is more than RM 400, and if so, apply a 10% discount

7. Display the total cost and the discount (if any) to the user

For solving the above problem, we can use Python language, which is widely used for programming. We will use the Function method approach for system development. We will create a function for each step of the process, starting from taking input of the car type to displaying the total cost and discount. We will also define variables for each input and output that we will use in our code.The program will first take input of the car type from the salesperson. Based on this, it will calculate the car price by using if-else statements. Once the car price is calculated, we will calculate the maintenance charges by using the formula given in the problem. Then, we will calculate the budget expenses for each vehicle by using another formula. Finally, we will calculate the total cost for the vehicle by adding the maintenance charges and budget expenses. If the cost is more than RM 400, we will apply a 10% discount by using if-else statements. We will then display the total cost and discount to the user. Here is the Python code for the given problem:```
# function to calculate car price
def calculate_car_price(car_type):
   if car_type == "Toyota":
       car_price = 100000
   elif car_type == "Honda":

       maintenance_charges = 57
   else:
       maintenance_charges = 117
   mileage_charges = mileage * 10

   return total_charges
# function to calculate budget expenses
def calculate_budget_expenses(total_charges):
   if total_charges > 400:
       discount = 0.1 * total_charges

water at 20 o c is flowing steadily in a 20 cm diameter steel pipe at a flow rate of 0.05 m3 /s. determine the head loss for flow over a 50 m long section.

Answers

The head loss for flow over a 50 m long section of the 20 cm diameter steel pipe is approximately 2.41 meters.

The head loss for flow over a 50 m long section of a 20 cm diameter steel pipe with water flowing steadily at 20°C and a flow rate of 0.05 m³/s can be calculated using the Darcy-Weisbach equation. This equation is given as:

hf = f L (V²/2g)

where hf is the head loss in meters, f is the Darcy friction factor, L is the length of the pipe section in meters, V is the average flow velocity in m/s, and g is the acceleration due to gravity (9.81 m/s²).

Given:

Water is flowing steadily in a 20 cm diameter steel pipe.

Flow rate = 0.05 m³/s

Temperature of water = 20°C

Flow velocity (v) = Q/A = (0.05 m³/s) / (π (0.2 m)² / 4) = 0.996 m/s

Pipe diameter (D) = 20 cm = 0.2 m

L = 50 m

Let's calculate the Reynolds number (Re) and relative roughness (ε/D) first. Reynolds number can be calculated as:

Re = V D/ν

where ν is the kinematic viscosity of water at 20°C, which can be taken as 1.002 x 10⁻⁶ m²/s (at 20°C).

So, Re = (0.996 m/s) (0.2 m) / (1.002 x 10⁻⁶ m²/s) = 1.98 x 10⁵

Since the Reynolds number is greater than 4000, the flow is turbulent.

Relative roughness can be calculated as:

ε/D = 0.000045 (given) / 0.2 m = 2.25 x 10⁻⁴

Now, we can calculate the Darcy friction factor (f) using the Moody chart or Colebrook-White equation. For this problem, we will use the Colebrook-White equation, which is:

1/√f = -2.0 log10[(ε/D)/3.7 + 2.51/Re √f]

Rearranging this equation and squaring both sides, we get:

f = [1 / {-2.0 log10[(ε/D)/3.7 + 2.51/Re √f]}]²

Substituting the values, we get:

f = 0.019

The head loss for flow over a 50 m long section of the steel pipe is given as:

hf = f L (V²/2g)

= (0.019) (50 m) [(0.996 m/s)² / (2 x 9.81 m/s²)]

≈ 2.41 m

To count the number of times a given element in an array is smaller than the element that comes immediately before it, you can use the following pseudocode:

1. Initialize a variable `count` to 0.

2. Iterate over the array from index 1 to the last index.

3. For each element at index `i`, compare it with the element at index `i-1`.

4. If the current element is smaller than the previous element, increment `count` by 1.

5. After the loop, the value of `count` will represent the number of times a smaller element is found.

Pseudocode:

```

count = 0

for i = 1 to SIZE-1 do

   if SP500[i] < SP500[i-1] then

       count = count + 1

   end if

V0 = - 10 + 16.66e^(-1000t) - 6.66e^(-3333.33t)

Thus the equation of the voltage is given as

V0 = - 10 + 16.66e^(-1000t) - 6.66e^(-3333.33t).

(b)Now, let's plot vo(t) as a function of time starting from t<0 s.

Here's how to plot vo(t) as a function of time:

The graph below shows the vo(t) graph;

Therefore, the plot vo(t) as a function of time starting from t<0 s is shown in the graph above.

The use of self-service analytics can introduce some new problems for an organization. Describe at least two potential issues organizations may face when implementing self-service analytics. What can the organizations do to mitigate these issues?

Answers

The use of self-service analytics can introduce some new problems for an organization. Two potential issues organizations may face when implementing self-service analytics include inaccurate data analysis and security concerns.

Self-service analytics can give access to many people in an organization to analyze the data without any training in data analysis and without understanding the data. This may result in inaccurate data analysis and an erroneous conclusion, which may negatively affect the decision-making process.In addition, self-service analytics increases the risk of data security breaches and privacy violations as access to data is provided to more people. In case the data is leaked, the organization will be faced with loss of trust from customers, reduced revenue, and legal implications. Organizations can mitigate these issues by implementing a data governance framework, which ensures data accuracy, privacy, and security. Data governance ensures the accuracy and completeness of data by establishing processes for data collection, data storage, and data quality. A clear set of policies should be put in place to control access to sensitive data, ensuring that only authorized people can access it. This will reduce the risk of data breaches. Furthermore, it is essential to provide training to employees on data analysis and data privacy to mitigate the risks that come with self-service analytics. Employees who use the data should be taught how to use it effectively and how to protect it. They should also understand the legal implications and the importance of maintaining data accuracy and privacy.

Self-service analytics is an essential tool for organizations as it enhances decision-making and improves the efficiency of the organization. However, organizations should be aware of the risks that come with it, including data security breaches, privacy violations, and inaccurate data analysis. Organizations can mitigate these risks by implementing a data governance framework and providing training to employees.

A relational database model is a representation of an organizational structure. The basis for data storage is a table that corresponds to the relational model.

There are three main types of relationships between entities in a relational database, which are as follows:

1. One-to-One Relationship

2. One-to-Many Relationship

3. Many-to-Many Relationship

1. One-to-One Relationship: When each item in the first table corresponds to only one item in the second table and vice versa, a one-to-one relationship exists between two tables. In the Tiny College, there is no such relationship between the entities.

2. One-to-Many Relationship: When each item in the first table corresponds to many items in the second table, a one-to-many relationship exists between two tables. In Tiny College, the following are the one-to-many relationships:

a. A student can take many courses.

b. A course can have many students.

c. A department can offer many courses.

d. A professor can teach many courses.

Business rules for the one-to-many relationships:

a. A student may not be enrolled in more than one class section for a specific course during the same semester.

b. When a student takes a course, they are expected to finish it.

c. A course must have a section in order for students to enroll in it.

3. Many-to-Many Relationship: When each item in the first table corresponds to many items in the second table and vice versa, a many-to-many relationship exists between two tables. In Tiny College, the following are the many-to-many relationships:

a. A course can have many class sections, and a class section can belong to many courses.

b. A student can be enrolled in many class sections, and a class section can have many students.

Business rules for the many-to-many relationships:

a. A student's enrollment in a class section can be dropped or added at any time before the deadline. The student will receive a W if they withdraw from the course after the deadline.

b. A class section must be taught by a single professor, and a professor can teach many class sections.

Consider the following sequences.
a = 0, 1, 2, ... , 10, b = 7, 9, 11, ... , 17, c = 0, 0.5, 1, 1:5, ... , 2,
d = 0, -1.5, -3, ..., -18
Use np.arange, np.linspace and np.r functions to create each sequence.
Give names as:
a_arrange a_linspace a_r
b_arrange b_linspace b_r
c_arrange c_linspace c_r
d_arrange d_linspace d_r

Answers

The given question is asking to create four different sequences with three different functions and then to give them some names.

The first sequence is a simple sequence with values from 0 to 10. To create this sequence, we can use the numpy.arange function with the parameter 11 as shown below:

np.arange(11)

The second sequence is a bit different, it starts from 7 and goes to 17, but with a step of 2. We can achieve this by using the same function as above but with some additional parameters:

np.arange(7, 18, 2)

The third sequence is a bit tricky, it is not a simple sequence like the first two. It starts from 0, goes to 2, but with a difference of 0.5.

To create this sequence, we can use the numpy.linspace function with the parameters 0, 2, and 5 as shown below:

np.linspace(0, 2, num=5)

The last sequence is a bit similar to the first one but with negative values and a step of -1.5. We can use the same function as above but with some different parameters:

np.arange(0, -19, -1.5)

Now, we have created all four sequences with the given functions, and we need to give them names. The names are given as follows:a_arrange, a_linspace, a_r for sequence a.b_arrange, b_linspace, b_r for sequence b.c_arrange, c_linspace, c_r for sequence c.d_arrange, d_linspace, d_r for sequence d.This is how we can create the given sequences with the given functions and then give them some names.

In conclusion, the given sequences are created with the help of numpy functions arange, linspace and named as given in the question.
