Answer:
P₂ = 0.5 W
Explanation:
It is given that,
The attenuation of a signal is -10 dB.
We need to find the final signal power if it was originally 5 W.
Using attenuation for signal :
[tex]dB=10\text{log}_{10}(\dfrac{P_2}{P_1})[/tex]
Put dB = -10, P₁ = 5 W
Put all the values,
[tex]-10=10\text{log}_{10}(\dfrac{P_2}{5})\\\\-1=\text{log}_{10}(\dfrac{P_2}{5})\\\\0.1=\dfrac{P_2}{5}\\\\P_2=5\times 0.1\\\\P_2=0.5\ W[/tex]
So, the final signal power is 0.5 W.
The final signal power if it was originally 5W is; 0.5 W
Signal PowerWe are given;
Attenuation signal; dB = -10 dBOriginal signal power; P1 = 5 WFormula for attenuation signal is;
dB = 10log_10_ (P2/P1)
Where P2 is final signal power
Thus;
-10 = 10log_10_(P2/5)
-10/-10 = log_10_(P2/5)
-1 = log_10_(P2/5)
0.1 = P2/5
P2 = 0.1 × 5
P2 = 0.5 W

How many times will line 7 be executed when the following code is run?
String str = "rebellion";
int i = 0;
int j = str.length() - 1;
String result = "";
while (i < j)
{
result = str.substring(i, i + 1) + result + str.substring(j, j + 1);
i++;
j--;
}
System.out.println(result);
(Java)
Answer:
4 times
Explanation:
Required.
How many times will line 7 be executed?
Line 2 initialises i to 0
Line 3 subtracts 1 from the length of "rebellion" , the result of the subtraction is then saved in J
So:
j = 9 - 1
j = 8
From line 2 and line 3, we have that:
i = 0 and j = 8
Line 4 is an iteration that is repeated as long as i is less than j
Line 7 will be executed, for the first time as: i < j because 0 < 8
i is incremented to 1 and j is reduced to 7
Line 7 is then executed again, the second time because 1 < 7
i is incremented to 2 and j is reduced to 6
Line 7 is then executed again the third time because 2 < 6
i is incremented to 3 and j is reduced to 5
Line 7 is then executed again the fourth time because 3 < 5
i is incremented to 4 and j is reduced to 4
At this stage, line 7 will no longer be executed because I is no longer less than as 4 = 4.
Hence, number of execution is 4 times

User max owns a directory games, containing a text file called ourgames.txt that he shares with users belonging to the group gameplayers. Those users may read and execute this file, but not delete it. They may not add other files to the directory. Others may neither read, write, nor execute anything in games. What would be the appropriate ownerships and permissions for both directory games and the file ourgames.txt look like
Answer:
The directory games folder: drwxr-x---
ourgames.txt files : -rwxr-x---
Explanation:
The directory games and the ourgames.txt file are owned by max who has read, write and execute permissions for both, where the 'd' in the first column represents the directory. The gameplayers group has read and execute permissions represented by the 'r' and 'x' letters. The other group is the third section with just dashes which means no permission is granted for the file.
Write a recursive function named double_digits that accepts an integer as a parameter and returns the integer obtained by replacing every digit with two of that digit. For example, double_digits(348) should return 334488. The call double_digits(0) should return 0. Calling your function on a negative number should return the negation of calling it on the corresponding positive number; for example, double_digits(-789) should return -778899.

Analyze the needs of the National Security team and help them articulate its problems, develop solutions to meet its needs, and deliver a recommendation that is aligned with the extant national objectives.
Answer:
Following are the solution to this question:
Explanation:
The Council's role has been to assist and support the President regarding national security and foreign policies ever since its inception under Truman. This Committee often acts as the primary arm of a President to organize these initiatives between government agencies.
The Leader holds sway over the NSC. Its Secretary Of Defense offers a range of options for the Administration on policy issues. The director of national intelligence helps prepare the administration's foreign travel, among other tasks, and offers context memos and staffing for the administration's discussions and phone interviews involving global leaders.
Safety investments were taken for many years utilizing threat cost-benefit analysis wherein the effect metric has been largely focused on even a risk reduction comparative estimate. To evaluate investment decisions, most aim to conduct similar analyses.
Even so, the potential threat is much harder to measure for high-security installations that potential hazard since the likelihood of an attack is highly uncertain and depends strongly on undefinable psychological factors like deterrence as well as the intensity of enemy goals.

What should you do
Answer:
Damien would be assign the Manage Documents permission while Sally on the other hand will be assign the permission to print.
Explanation:
Based on the information given in order for me to assign a restrictive permission that will meet the requirements of the sale manager's what I will do is for me to assign the Manage Documents permission to Damien reason been that Damien only needs to stop and resume the documents for all users in which he does not need to change the printer properties and to assign the permission to print to Sally reason been that Sally only needs to connect to a printer and to print documents in which she will then stop and resume her own print jobs.

Multi-programming (or multi-tasking) enables more than a single process to apparently execute simultaneously. How this can be achieved on a uni-processor?]
Answer:
In multi-programming, you use semaphore constructs to protect shared resources. Your program thread or process will block if you want to claim a semaphore when another thread or process has it claimed.
Generally you need to keep the code scope of the claimed semaphore (a.k.a. the critical section) as small as possible, and also, prevent claiming another semaphore within a given critical section.
Course Aggregation Many times, departments are only interested with how students have done in courses relative to a specific major when considering applicants for admission purposes.
For this problem you are given a dictionary where the keys are strings representing student ids and the values are dictionaries where the keys represent a course code and the value represents a grade. Your task is to write a function that given a dictionary of the described format and a prefix for course codes, return a dictionary where each key is a student id and the corresponding value is the average grade of the student only in courses that start with the given prefix.
def course_grader (student_to_grades, course_prefix): ({str, {str, float}}) -> {str, float} I: a dictionary containing the grades of students (as described above) and a course code prefix P: compute and store the average grade of all students only for courses that start with the given course prefix 0: a dictionary of student ids to average grades as described in the Processing step pass
Answer:
def course_grader(student_to_grades, course_prefix):
student_grades = dict()
for key, value in student_to_grades.items():
grade_score = 0
for course,grade in value.items():
if course_prefix == course:
grade_score += grade
student_grades[key] = grade_score / len(value.keys())
return student_grades
Explanation:
The course_grader function is a python program that accepts two arguments, the student dictionary and the course prefix. The function returns a dictionary of the student id as the key and the average grade of the student as the value.
Which of the following apertures will give you the shallowest depth of field?
a)2.8
b)5.6
c)11
d)22
e)2
50 points and brainliest
Answer:
a.2.8
The f-stops work as inverse values, such that a small f/number (say f/2.8) corresponds to a larger or wider aperture size, which results in a shallow depth of field; conversely a large f/number (say f/16) results in a smaller or narrower aperture size and therefore a deeper depth of field.

A company is performing an analysis on the computers at its main office. The computers are spaced along a single row. The analysis is performed in the following way: 1. Choose a contiguous segment of a certain number of computers, starting from the beginning of the row. 2. Analyze the available hard disk space on each of the computers. 3. Determine the minimum available disk space within this segment.
Answer:
array = input("Enter the list of computer memory: ").split(',')
int_arr = [int(x) for x in array]
segment = int(input("Enter the length of segment to analyze: "))
list_len = len(int_arr)
segList = []
mini = []
for x,i in enumerate(int_arr):
seg = int_arr[i-1:segment+i-1]
if len(seg) == segment:
segList.append(seg)
for x in segList:
mini.append(min(x))
result = mini.index(min(mini))
print("Segment with the minimum memory is: ",segList[result])
Explanation:
The python program prints out the segment after analysis, with the smallest disk memory space. The code gets the array of computer rows from the user input and segments the array with the number of segment input, then the minimum is compared for all segments in the network.

Jorge is sending a message to Thomas but would like a copy sent to his external email address as well. Jorge does not want Thomas to see this copy that was sent.
Which mail field will Jorge use to achieve this goal?
To:
From:
CC:
BCC:
Answer: BCC (fourth choice)
=================================================
Explanation:
CC stands for "carbon copy".
BCC stands for "blind carbon copy".
Filling out forms is a tedious process. It's even more tedious when you have to repeat yourself multiple times. Carbon copy paper technology allows you to fill out one form and have those inputted entries be copied to the layers below. In terms of email, a carbon copy (CC) email is just an email sent to more than one person. In the CC line, recipients can see who the other people are in the email chain.
In contrast, a blind carbon copy is where the recipients cannot see who is in the BCC line. This allows Jorge to send the message copy to an external address without Thomas knowing.

g Create a Java program that takes input of a list of integers from the user, stores them into an array and then finally uses the array contents to output the list of integers in reverse. The user's input begins with the number of integers to be stored in the array. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers.Create a Java program Ex: If the input is: 8 5 2 3 4 10 6 8 9
Answer:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
int arraylent;
Scanner input = new Scanner(System.in);
System.out.print("Array Length: ");
arraylent= input.nextInt();
int[] myarray = new int[arraylent];
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
}
}
Explanation:
This declares the length of the array
int arraylent;
This next two lines prompt and get the array length i.e. number of input
System.out.print("Array Length: ");
arraylent= input.nextInt();
This declares the array as type integer. And the length of the array is gotten from the user input
int[] myarray = new int[arraylent];
This gets the items of the array
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
This reverse and prints the array
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
Write a program that declares three one-dimensional arraysnamed miles, gallons, and mpg. Each array should be declared in main() and should becapable of holding ten double-precision numbers. The numbers that should be stored in miles are240.5, 300, 189.6, 310.6, 280.7, 206.9, 199.4, 160.3, 177.4, and 192.3. The numbers should bestored in gallons are 10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, and 8.4.
Answer:
#include <iostream>
using namespace std;
int main(){
double miles[10] = {240.5, 300, 189.6, 310.6, 280.7, 206.9, 199.4, 160.3, 177.4, 192.3};
double gallons[10] = {10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, 8.4};
double mpg[10];
for (int i = 0; i < 10; i++){
mpg[i] = miles[i]/ gallons[i];
cout << "mpg: " << mpg[i] << endl;
}
}
Explanation:
The C++ source code declares three arrays miles, gallons and mpg with an array length of 10. The gallons and miles arrays are assigned 10 array items each and they are used to push values to the mpg array in the for loop statement. The result of each item in the mpg array is displayed on the screen.
