A capacitor of capacitance 102/π µF is connected across a 220 V, 50 Hz A.C. mains. Calculate the capacitive reactance, RMS value of current and write down the equations of voltage and current.
Answer:
The capacitive reactance will be "100Ω" and RMS value of current is "2.2 A". A further explanation is provided below.
Explanation:
Given:
[tex]C =\frac{10^2}{\pi}\times 10^{-6} \ F[/tex]
[tex]V_{RMS}=220 \ V[/tex]
[tex]f = 50 \ Hz[/tex]
Now,
The capacitive reactance will be:
⇒ [tex]X_c=\frac{1}{\omega C} =\frac{1}{2 \pi f C}[/tex]
[tex]=\frac{1}{2\times \pi\times 50\times \frac{10^{-4}}{\pi} }[/tex]
[tex]=100 \ \Omega[/tex]
RMS value of current will be:
⇒ [tex]I_{RMS}=\frac{V_{RMS}}{X_c}[/tex]
[tex]=\frac{220}{100}[/tex]
[tex]=2.2 \ A[/tex]
So that,
⇒ [tex]V_m=220\times \sqrt{2}[/tex]
[tex]=311 \ V[/tex]
⇒ [tex]I_m=2.2\times \sqrt{2}[/tex]
[tex]=3.1 \ A[/tex]
hence,
The equation will be:
⇒ [tex]\nu=311 sin31 \ 4t[/tex]
and,
⇒ [tex]i=3.1 sin(314t+\frac{\pi}{2} )[/tex]

print(a+b)
print(a*b)
2.)
a = int(input('enter an integer values '))
b = int(input('Enter another integer value' ))
print(a+b)
print(a*b)
3.)
Take side of a square from user and print area and perimeter of it.
def square(a):
area = a**2
perimeter = 4*a
print(area, perimeter)
Explanation:
Code written in python :
The first function named two, takes to arguments a and b ;
The sum of integers a and b is taken and displayed using ; print(a+b)
The product of integers a and b is taken and displayed using ; print(a*b)
2.)
User can enter an input and converted to an integer value using the command ;
int(input()) ; the sum and product of these values are displayed using :
print(a*b) and print(a+b)
The Area and perimeter of a square requires the side length, which is taken as the argument a in the square function defined.

Answer: 2.125
Explanation
You are the IT administrator for a small corporate network. The employee in Office 1 needs your assistance managing files and folders. Your task is to use the command prompt to complete the following:
a. Create the D:\utilities\recover directory. Use the md or mkdir command to create (make) a directory.
b. Delete the D:\software\arch98 directory and all of its files.
c. Use the rd command to delete (remove) a directory.
d. Use the /s switch to remove the directory and all of its contents at once.
(a) mkdir /d D:\utilities\recover
or
mkdir D:\utilities\recover
(b) rd /s D:\software\arch98
Explanation:(a) To make a new directory we use the md or mkdir command followed by the name of the directory as follows;
mkdir [name_of_directory]
The name of the directory could also be a relative or absolute path depending on the request.
In the task, the specified directory uses an absolute path given as D:\utilities\recover. This path is in a drive D. Therefore, if you are in another drive different than D, to run this command, it is a great idea to do that with the /d switch.
In summary:
i. if in drive D, to make a directory D:\utilities\recover, type the following command;
mkdir D:\utilities\recover
ii. if otherwise in a different drive, type the following command.
mkdir /d D:\utilities\recover
(b) To delete a directory, we use the rd or rmdir command. If the directory has contents that also need to be deleted, we use the switch /s alongside the rd or rmdir.
In the task given, the directory to be deleted is D:\software\arch98. This includes deleting all of its files too. To do this, type the following command;
rd /s D:\software\arch98

int a[10],i,j,n,min,max,sum=0,temp;//defining integer variable
float avg;//defining floating point variable
cout<<"Please input the number of temperatures to be read: ";//print message
cin>>n;//input integer value
if(i>10)//use if to check array length greater than 10
return -1;//return integer value -1
for(j=0;j<n;j++)//defining loop to input value
{
cout<<"Input temperature: "<<endl;//print message
cin>>a[j];//holding value in loop
}
for(i=0;i<n-1;i++)//defining loop to compare array value
{
for(j=i+1;j<n-1;j++)//defining loop to compare array value
{
if(a[i]>a[j])//use if to compare array values
{
//swapping
temp=a[j];//holding array value in temp
a[j]=a[i];//holding value in first index of array
a[i]=temp;//holding temp value
}
}
}

for (i = 0; i < n; i++)//defining loop to compare array value
{
if (a[i] > max)//use if to compare max array value
{
max = a[i];//holding max array value
}
else if (a[i] < min)//use else if to compare min array value
{
min = a[i];//holding min array value
}
}
for(i=0;i<n;i++)//use loop to add array value
sum=sum+a[i];//adding array value
avg=(float) sum/n;//calculating avg of the array
std::cout.setf(std::ios::fixed);//using namespace
std::cout.precision(2);//using precision method
cout<<"The average temperature is: "<<avg<<endl;//print avg value with message
cout<<"The highest temperature is: "<<max<<endl;//print max value with message
cout<<"The lowest temperature is: "<<min<<endl;//print min value with message
return avg;//return avg value
}
int main()//defining main method
{
float k;//defining float variable
k=temperatures();//calling method
}

Write an application that inputs a five digit integer (The number must be entered only as ONE input) and separates the number into its individual digits using MOD, and prints the digits separated from one another. Your code will do INPUT VALIDATION and warn the user to enter the correct number of digits and let the user run your code as many times as they want (LOOP). Submit two different versions: Using the Scanner class (file name: ScanP2)
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
int n, num;
Scanner input = new Scanner(System.in);
System.out.print("Number of inputs: ");
n = input.nextInt();
LinkedList<Integer> myList = new LinkedList<Integer>();
for(int i = 0; i<n;i++){
System.out.print("Input Integer: ");
num = input.nextInt();
while (num > 0) {
myList.push( num % 10 );
num/=10;
}
while (!myList.isEmpty()) {
System.out.print(myList.pop()+" ");
}
System.out.println();
myList.clear();
}
}
}
Explanation:
This declares the number of inputs (n) and each input (num) as integer
int n, num;
Scanner input = new Scanner(System.in);
Prompt for number of inputs
System.out.print("Number of inputs: "); n = input.nextInt();
The program uses linkedlist to store individual digits. This declares the linkedlist
LinkedList<Integer> myList = new LinkedList<Integer>();
This iterates through n
for(int i = 0; i<n;i++){
Prompt for input
System.out.print("Input Integer: ");
This gets input for each iteration
num = input.nextInt();
This while loop is repeated until the digits are completely split
while (num > 0) {
This adds each digit to the linked list
myList.push( num % 10 );
This gets the other digits
num/=10;
}
The inner while loop ends here
This iterates through the linked list
while (!myList.isEmpty()) {
This pops out every element of thelist
System.out.print(myList.pop()+" ");
}
Print a new line
System.out.println();
This clears the stack
myList.clear();
}
