Answer:

[tex]Attenuation = 0.458\ db[/tex]

Explanation:

Given

Power at point A = 100W

Power at point B = 90W

Required

Determine the attenuation in decibels

Attenuation is calculated using the following formula

[tex]Attenuation = 10Log_{10}\frac{P_s}{P_d}[/tex]

Where [tex]P_s = Power\ Inpu[/tex]t and [tex]P_d = Power\ outpu[/tex]t

[tex]P_s = 100W[/tex]

[tex]P_d = 90W[/tex]

Substitute these values in the given formula

[tex]Attenuation = 10Log_{10}\frac{P_s}{P_d}[/tex]

[tex]Attenuation = 10Log_{10}\frac{100}{90}[/tex]

[tex]Attenuation = 10 * 0.04575749056[/tex]

[tex]Attenuation = 0.4575749056[/tex]

[tex]Attenuation = 0.458\ db[/tex] (Approximated)

Answer:

c. rear = (rear + 1) % elements.length; elements[rear] = element;

Explanation:

In the above statement:

Name of the array is elements.

rear holds current index of elements array where current rear element of queue is stored. Front are rear are two open ends of the queue and the end from which the element is inserted into the queue is called rear.

element is the element that is required to enqueue into the queue

Enqueue basically mean to add an element to a queue.

Here it is assumed that the queue is not full. This means an element can be added to the queue.

It is also assumed that code also correctly increments numElements.

rear = (rear + 1) % elements.length; This statement adds 1 to the rear and takes the modulus of rear+1 to the length of the array elements[]. This statement specifies the new position of the rear.

Now that the new position of rear is found using the above statement. Next the element can be enqueued to that new rear position using the following statement:

elements[rear] = element; this statement sets the element at the rear-th (new position) index of elements[] array.

For example we have a queue of length 5 and there are already 4 elements inserted into this queue. We have to add a new element i.e. 6 to the queue. There are four elements in elements[] array and length of the array is 5 so this means the queue is not full. Lets say that rear = 3

elements.length = 5

rear = 3

Using above two statements we get.

rear = (rear + 1) % elements.length;

       = 3 + 1 % 5

       = 4%5

      =  4

This computes the new position of rear. So the new position of rear is the 4-th index of elements[]. Now next statement:

elements[rear] = element;

elements[4] = 6

This statement adds element 6 to the 4-th index of elements[] array.

Thus the above statement enqueues element (element 6 in above example) into the queue.

       System.out.println("Please enter the number of years");

       //Receive the input using the Scanner object and

       //Store the entered number of years in a variable ny

       int ny = input.nextInt();

       //Convert number of hours to minutes and

       //add the result to the nm variable

       nm += nh * 60;

       //Convert number of days to minutes and

       //add the result to the nm variable

       nm += nd * 24 * 60;

       //Convert number of weeks to minutes and

       //add the result to the nm variable

       nm += nw * 7 * 24 * 60;

       //Convert number of years to minutes and

       //add the result to the nm variable

       nm += ny * 52 * 7 * 24 * 60;

       //Display the number of minutes which is stored in nm

       System.out.println("The number of minutes is " + nm);

    }   //End main method

Answer:

I am writing a Python program. Let me know if you want the program in some other programming language.        

import string  #to use string related functions

def wordcount(filename):  # function that takes a text file name as parameter and returns the number of occurrences of every word in file

   file = open(filename, "r")  # open the file in read mode

   wc = dict()  # creates a dictionary

   for sentence in file:  # loop through each line of the file

       sentence = sentence.strip()  #returns the text, removing empty spaces

       sentence=sentence.lower() #converts each line to lowercase to avoid case sensitivity

       sentence = sentence.translate(sentence.maketrans("", "", string.punctuation))  #removes punctuation from every line of the text file

       words = sentence.split(" ")  # split the lines into a list of words

       for word in words:  #loops through each word of the file

           if len(word)>2:  #checks if the length of the word is greater than 2

               if word in wc:  # if the word is already in dictionary

                   wc[word] = wc[word] + 1  #if the word is already present in dict wc then add 1 to the count of that word

               else:  #if the word is not already present

                   wc[word] = 1  # word is added to the wc dict and assign 1 to the count of that word                

   for w in list(wc.keys()):  #prints the list of words and their number of occurrences

       print(w, wc[w])  #prints word: occurrences in key:value format of dict        

wordcount("file.txt") #calls wordcount method and passes name of the file to that method

Explanation:

The program has a function wordcount that takes the name of a text file (filename) as parameter.

open() method is used to open the file in read mode. "r" represents the mode and it means read mode. Then a dictionary is created and named as wc. The first for loop, iterates through each line (sentence) of the text file. strip() method is used to remove extra empty spaces or new line character from each sentence of the file, then each sentence is converted to lower case using lower() method to avoid case sensitivity. Now the words "hello" and "Hello" are treated as the same word.

sentence = sentence.translate(sentence.maketrans("", "", string.punctuation))  statement uses two methods i.e. maketrans() and translate(). maketrans() specifies the punctuation characters that are to be deleted from the sentences and returns a translation table. translate() method uses the table that maketrans() returns in order to replace a character to its mapped character and returns the lines of text file after performing these translations.

Next the split() method is used to break these sentences into a list of words. Second for loop iterates through each word of the text file. As its given to ignore words of length 2 or less, so an IF statement is used to check if the length of word is greater than 2. If this statement evaluates to true then next statement: if word in wc:   is executed which checks if the word is already present in dictionary. If this statement evaluates to true then 1 is added to the count of that word. If the word is not already present  then the word is added to the wc dictionary and 1 s assigned to the count of that word.

Next the words along with their occurrences is printed. The program and its output are attached as screenshot. Since the frankenstein.txt' is not provided so I am using my own text file.

Answer:

The programming language is not stated;

The program written in C++ is as follows (See Explanation Section for detailed explanation);

#include<iostream>

using namespace std;

int main()

{

 int numdays;

 cout<<"Number of days of mileage: ";

 cin>>numdays;

 int miles[numdays];

for(int i=0;i<numdays;i++)

{

 cout<<"Miles traveled on day "<<i+1<<": ";

 cin>>miles[i];

}

 int total = 0;

 for(int i=0;i<numdays;i++)

{

 total+=miles[i];

}

cout<<"Total mileage traveled: "<<total;

 return 0;

}

Explanation:

This line declares the number of days of mileage

 int numdays;

This line prompts user for days of mileage

 cout<<"Number of days of mileage: ";

This line accepts input from the traveler for days of mileage

 cin>>numdays;

This line creates an array

 int miles[numdays];

The italicized is an iteration that collects the user input for each day

for(int i=0;i<numdays;i++)

{

 cout<<"Miles traveled on day "<<i+1<<": ";

 cin>>miles[i];

}

This line initializes variable to 0

 int total = 0;

The italicized is an iteration that adds up the mileage traveled by the traveler each day  

 for(int i=0;i<numdays;i++)

{

 total+=miles[i];

}

This line prints the total miles traveled

cout<<"Total mileage traveled: "<<total;

Given that,

Size of each sandbox = 16 MB

Address space = 32- bit

We need to calculate the total size of address space

Using formula of total size

[tex]\text{total size of address space}=2^{32}[/tex]

[tex]\text{total size of address space}=4\times10^9[/tex]

[tex]\text{total size of address space}=4\ Gigabytes[/tex]

We need to calculate the total of applets

Using formula of total applets

[tex]\text{total applets}=\dfrac{\text{total size of address space}}{\text{size of one applet}}[/tex]

Put the value into the formula

[tex]\text{total applets}=\dfrac{4\ GB}{16\ MB}[/tex]

[tex]\text{total applets}=\dfrac{4\times1024\ MB}{16\ MB}[/tex]

[tex]\text{total applets}=256[/tex]

Hence,  The total of applets are 256.

A total of 6,000 bps of bandwidth is used by the distributed routing algorithm

Explanation:

This is a bandwidth requirement question.

We proceed as follows;

To calculate the total number of bits for a routing table, we use the following formula;

Routing table=Number of routers * length of cost

we are given the following parameters from the question;

Number of routers = 500

length of cost = 4 bits

Routing table = 500*4

=2000

Hence, a routing table is 2000 bits in length.

Now we proceed to calculate the bandwidth required on each line using the formula below;

Bandwidth = no.of seconds * no.of bits in routing table

Bandwidth required on each line = 3*2000

=6000

Answer:

simonPattern = 'RRGBRYYBGY'# stores the sequence of characters in simonPattern

userPattern  = input("Enter user pattern: ")  # prompts the user to enter user pattern and stores the pattern in userPattern

for x in range(len(simonPattern)):  #loops through entire length of simonPattern using x as index variable

   if userPattern[x] == simonPattern[x]:  # checks if the element at x-th index of userPattern matches the element at x-th index of simonPattern

       user_score = user_score + 1  # adds 1 to user score if above if condition evaluates to true

   else:  #if a mismatch occurs  

       break  #loop break if mismatch occurs

print("User Score:",user_score) #prints the computed user score

Explanation:

The program first declares a simonPattern string variable and assign it a sequence of characters. You can also prompt to enter the Simon pattern as

simonPattern = input("Enter Simon pattern:")

If you want to hard code the values of both simonPattern and userPattern then change the first two statements after user_score =0 statement as:

simonPattern = 'RRGBRYYBGY'

userPattern  = 'RRGBBRYBGY'

Now I will explain the working of the for loop.

for x in range(len(simonPattern)):

len method is used which returns the length of the string stored in simonPattern. For example if simonPattern = 'RRGBRYYBGY' then len returns 10

range method is used to generate a sequence of numbers for x. This means value of x starts from 0 and it  keeps incrementing to 1 until the length of the simonPattern is reached.

At first iteration:

Let suppose user enters the pattern: RRGBBRYBGY

x starts at index 0. Value of x=0 is less than the length of simonPattern i.e. 10 so the body of loop executes. The body of loop contains the following if statement:

if userPattern[x] == simonPattern[x]:

It matches both the string for the value of x.

if userPattern[0] == simonPattern[0]:

First character (at 0th index) of userPattern is R and in simonPattern is also R so this statement executes:  user_score = user_score + 1  which adds 1 to the user_score. So user_score=1

Next iteration:

x=1

if userPattern[1] == simonPattern[1]:

Second character (at 1st index) of userPattern is R and in simonPattern is also R so this statement executes:  user_score = user_score + 1  which adds 1 to the user_score. So user_score=2

Next iteration:

x=2

if userPattern[2] == simonPattern[2]:

Third character (at 12nd index) of userPattern is G and in simonPattern is also G so this statement executes:  user_score = user_score + 1  which adds 1 to the user_score. So user_score=3

Next iteration:

x=3

if userPattern[3] == simonPattern[3]:

Fourth character (at 3rd index) of userPattern is B and in simonPattern is also B so this statement executes:  user_score = user_score + 1  which adds 1 to the user_score. So user_score=4

Next iteration:

x=4

if userPattern[4] == simonPattern[4]:

Fifth character (at 4th index) of userPattern is B and in simonPattern is R so the if part does not execute and program moves to the else part which has a break statement which means the loop break. The next print(user_score) statement print the value of user_score. As user_score=4 computed in above iterations so output is:

User Score: 4

Answer:

The other answer was so close, but the _ was left out so the answer was wrong.

simon_pattern = input()

user_pattern  = input()

for x in range(len(simon_pattern)):

The summary including its given problem is outlined in the following section on the interpretation.

Explanation:

That's not entirely feasible, since at least n similarities have to be made to order n quantities. Find the finest representation where the numbers of 1 to 10 have already been arranged.

⇒ 1 2 3 4 5 6 7 8 9 10

Let's say that we identify one figure as the key then compared it towards the numbers across the left. Whether the correct number is greater, therefore, left number, are doing nothing to switch the location elsewhere.

Because although the numbers have already been categorized 2 has always been compared to 1 which would be perfect, 3 becomes especially in comparison to 2 and so much more. This should essentially take 9 moves, or nearly O(n) moves.

If we switch that little bit already

⇒ 1 3 2 4 5 6 7 8 9 10

3 Is contrasted with 1. 2 will indeed be matched against 3 as well as 2. Since 2 has indeed been exchanged, it must, therefore, be matched with 1 as there might be a case whereby each number z exchanged is greater than the number Y as well as the quantity X < Y.

Only one adjustment expanded the steps which culminated in n+1.

It should be noted that it won't be possible because at least n similarities have to be made to order n quantities.

From the information given, it should be noted that it's not possible for the engineer to implement an algorithm that can sort n elements (e.g., numbers) in fewer than n steps.

This is because there are at least n similarities have to be made to order n quantities. In this case, the numbers of 1 to 10 have already been arranged. When a number is greater, it should be noted that the left number will do nothing to switch the location elsewhere.

Therefore, the information given by the engineer isn't feasible.

   if second != -1:#defining if block to calculate second variable slicing

       return s[len(sub)+second:]#return s variable value

print(after_second("heyyoheyhi","hey"))#defining print method to call after_second method

print(after_second("11223344554321","3"))#defining print method to call after_second method

Output:

hi

44554321

Explanation:

In the above python code a method "after_second" is declared, that accepts two-variable "s, and sub" as the parameter inside the method a first variable is declared that uses the inbuilt method "find" to find the value and stores it value. In the next step, two if blocks are used, in which both if blocks use the slicing to checks its value is not equal to "-1".
