The attenuation of a signal is -10 dB. What is the final signal power if it was originally
5 W?
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

Explain the consequences of using bits to represent data.
Answer:
Each description of a PC needs to clarify how the PC handles data: numbers, text, pictures, sound, films, directions.
Using bits to represent data implies that the computer has to use a lot of memory since every character has a group of bits representing it.
The PC is an electronic gadget. Every one of its wires can either convey electric flow or... not convey current. Thus, similar to a light switch, it sees just two states. Incidentally, this is sufficient to make the entire thought work. Indeed, any framework that can speak to in any event two states can speak to data. Take, for instance, the Morse code that is utilized in telecommunication. Morse is a sound transmission framework that can convey a short signal (spoke to by a dab) and a long beeeeeep (spoke to by a scramble). Any letter or number can be spoken to by a mix of these two images. Snap here to see a Morse interpreter.
Explanation:
Essentially with PCs. To speak to a number, we utilize the parallel number-crunching framework, not the decimal number framework that we use in regular day to day existence. In the double framework, any number can be spoken to utilizing just two images, 0 and 1. (Morse is nearly, yet not exactly (because of the delays between letters) a paired framework. A framework firmly identified with Morse is utilized by PCs to do information pressure (more about this later).
A bit which is also called a binary digit is the smallest unit of data. A combination of two or more bits is regarded as bytes.
A bit is usually processed by the electrical parts of a computer system. Internet speed is measured in bits and it reflects two opposite commands which could be either yes/no , on/off etc.
The consequence of using bit to represent data is due to the advantages which includes:
Easy computation : Due to the simplicity and it involving less complex calculations, the bits gives room for less errors.Ease of Coding: The bits is the simplest and smallest unit of data which makes it less stressful when used in coding operations.Ease of Operation: Devices which operates with the bits system makes it easier for humans to operate when compared to other complex forms.Read more on https://brainly.com/question/19667078

Explanation:
I am having trouble with doing this code on Python:Develop the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.Ex: If the input is:2011 18000 2018where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770Note: print_info() should use three spaces for indentation.
Answer:
class Car:
def __init__(self, model_year, purchase_price):
self.model_year = model_year
self.purchase_price = purchase_price
self.current_year = 0
self.current_value = 0
def set_current_year(self, year):
self.current_year = year
def calc_current_value(self, current_year):
if self.current_year == 0:
return "Must first input the current year"
depreciation_rate = 0.15
car_age = current_year - self.model_year
self.current_value = round(self.purchase_price - (car_age * (self.purchase_price * 0.15)))
def print_info(self):
print("Car's information:")
print(f"Model year: {self.model_year}")
print(f"Purchase price: {self.purchase_price}")
if self.current_value > 0:
print(f"Current value: {self.current_value}")
else:
print("Current value: Unknown")
Explanation:
The python program above defines the class "Car" that accepts the model year and purchase price of an instance. The class has a set method for the current year variable that is used to calculate and update the current value variable of the object. The print_info method prints the car model year, purchase price and its current value after nth years.

Review how to write a for loop by choosing the output of this short program.
for counter in range(3):
print(counter * 2)
Please explain it to me, I’m not learning Bc I don’t have a teacher.
Answer:
The output is:
0
2
4
Explanation:
First of all, the print statement must be indented with a tab, otherwise it is not part of the for loop.
The range(3) creates an array with values 0,1,2. The variable 'counter' gets those values one after another, and the print statement outputs this value doubled, hence the 0, 2 and 4 output.
Which of the following scenarios is most likely to give you the shallowest depth of field?
a) 18mm lens at f5.6, subject 20 feet away.
b) 50mm lens at f22, subject 6 feet away.

Explanation:
Adam is so good at playing arcade games that he will win at every game he plays. One fine day as he was walking on the street, he discovers an arcade store that pays real cash for every game that the player wins - however, the store will only pay out once per game. The store has some games for which they will pay winners, and each game has its own completion time and payout rate. Thrilled at the prospect of earning money for his talent, Adam walked into the store only to realize that the store closes in 2 hours (exactly 120 minutes). Knowing that he cannot play all the games in that time, he decides to pick the games that maximize his earnings
Sample game board at the arcade GAME COMPLETION TIME (in minutes) PAYOUT RATE Pac-man 90 400 Mortal Kombat 10 30 Super Tetris 25 100 Pump it Up 10 40 Street Fighter II 90 450 Speed Racer 10 40
An acceptable solution is the one where it still picks the best earnings even when the list of games or completion times or payout rates change.
Question:
Write code in Java/Scala/Python to help Adam pick the sequence(s) of games that earn him the most money?.
Then, assume you have a variable list of games and their payout rates. What is the best way to pick the games that earn you the most?
Input Explanation
The first line of input is always an integer denoting many lines to read after the first line. In our sample test case, we have 6 in the first line and 6 lines after the first line, each having a game, completion_time and payout_rate.
In each data line, the game, completion_time and payout_rate are separated by a ','(comma).
The games board may change but the store still closes in 120 minutes.

PLS HELP ASAP- Select the correct text in the passage.
Which concept explained in the paragraph below means that data always remains consistent?
Specific programs have some tasks that a computer must perform in parallel with others. These tasks (such as the performance of the same set of operations on different data sets) often work in parallel clusters. In such cases, a separate thread of execution handles each separate task. You can think of a thread as a sequence of instructions that computers can manage independently.
It is possible for different threads to access the same data elements and change their values, and this can lead to an inconsistent state of information. For instance, if multiple programs access a shared variable x and change its value, the variable will not contain the correct value at the end of the programs. We can prevent such inconsistencies by using locks. A thread puts a lock on shared data, and releases this lock only after completing its operations.

Explanation:
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.
Answer:
This question is answered using Java
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Length of array: ");
int len = input.nextInt();
int[] intArray = new int[len];
for(int i = 0; i<len;i++){
intArray[i] = input.nextInt();
}
for(int i = len-1; i>=0;i--){
System.out.print(intArray[i]+" ");
}
}
}
Explanation:
This line prompts user for length of array
System.out.print("Length of array: ");
This gets the length of the arrau
int len = input.nextInt();
This declares the array as integer
int[] intArray = new int[len];
The following iteration gets input to the array
for(int i = 0; i<len;i++){
intArray[i] = input.nextInt();
}
The following iteration prints the array in reversed order
for(int i = len-1; i>=0;i--){
System.out.print(intArray[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]);

B) programmers don't need to worry about race conditions.
C) a thread cannot block inside a critical section.
D) deadlock cannot occur.
Answer:
A. Management of entry and exit code is managed by OpenMP library reducing the possibility of programming errors
Explanation:
This is a multiple choice question and this is the answer because:
1. OpenMp is inclusive of an APL/compiler directives:
2. any code which follows #pragma omp parallel is a parallel region and it is performed by large number of threads that are same as the number of processing cores that are in the system.
3. The critical-section compiler directive acts more like a binary semaphore or mutex lock,it makes sure that only one thread is active in the critical section at the same time.
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.

Suppose a switch is built using a computer work station and that it can forward packets at a rate of 500,000 packets per second, regardless (within limits) of size. Assume the workstation uses direct memory access (DMA) to move data in and out of its main memory, which has a bandwidth of 2 Gbps, and that the I/O bus has a bandwidth of 1 Gbps. At what packet size would the bus bandwidth become the limiting factor
Answer:
When the transmission exceeds 667 packets
Explanation:
In computer networking, a packet is a chunk of data transmitted across the network. The packet size of an Ethernet network is 1.5kilobytes, while the packet size of an IP packet payload is 64 kilobytes.
A switch is a physical network device that connects nodes or workstations while communicating the packets (or frames). The I/O bus size bandwidth is 1Gbps which allows approximately 667 packets. Once this packet size is crossed, the bus becomes a limiting factor or bottle neck.
