The answer is C: Both of the two students are correct.

Voltage in very simple terms is what makes electric charges move. It is that push or force that causes charges to move in an electrical conductor. Thus, student A is correct since voltage is a specific measure of potential energy that exists and is always relative between two points. On the other hand, power is the rate, per unit time, at which electrical energy travels. Electrical power (P) is the product of both voltage and current and not either one separately. It is a function of voltage and current. Thus, student B is also correct.

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the fi
Aleksandr [31]

Answer:

Explanation:

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.  

  double alpha[50];

   for (int i=0;i<25;i++)

   {

       alpha[i]=i*i;

       alpha[i+25]=(i+25)*3;

  }

2. Output the array so that exactly ten elements per line are printed.  

   for (int i=0;i<50;i++)

   {

       cout<<i+1<<". "<<alpha[i]<<" ";

       if (((i+1)%10)==0)

       {

           cout<<endl;

       }

   }

3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.  

   double alpha[50];

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

   }

   for (int i=0;i<50;i++)

   {

       cout<<i+1<<". "<<alpha[i]<<" ";

       if (((i+1)%10)==0)

       {

           cout<<endl;

       }

   }

4. Write the code that computes and prints the average of elements of the array.  

   double alpha[50],temp=0;

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

       temp+=alpha[i];

   }

   cout<<"Average :"<<(temp/50);

5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.

   double alpha[50],temp=0;

   for (int i=0;i<50;i++)

   {

       alpha[i]=rand()%101;

       if(alpha[i]==100)

       {

           temp++;

       }

   }

   cout<<"Elements Exacctly 100 :"<<temp;

Please note:  If you put  each of above code to the place below comment  it will run perfectly after compiling

#include <iostream>

using namespace std;

int main()

{

   // If you put  each of above code here it will run perfectly after compiling

   return 0;

}

Finger [1]

Answer:

public static void PrintShampooInstructions(int numberOfCycles){

       if (numberOfCycles<1){

           System.out.println("Too Few");

       }

       else if(numberOfCycles>4){

           System.out.println("Too many");

       }

       else

           for(int i = 1; i<=numberOfCycles; i++){

               System.out.println(i +": Lather and rinse");

           }

       System.out.println("Done");

   }

Explanation:

I have used Java Programming language to solve this

Use if...elseif and else statement to determine and print "Too Few" or "Too Many".

If within range use a for loop to print the number of times

Write an expression that will cause "greater or equal to -10" to print if the value of userNum is greater than or equal to -10.
Lilit [14]

Answer:

Expression for the above problem in python language:

userNum=int(input("Enter the value of user_Num")) #it is used to take input.

if(userNum>(-10)): #if statement

   print("The value of the userNum is greator")

elif(userNum==(-10)): #elif statement

   print("The value of the userNum is equal to -10")

else: #else statement.

   print("The value of the userNum is small")

Output:

  • If the user input is (-10), it will print equal.
  • If the user input 10, it will print greator message.

Explanation:

  • The above program or expression is in python language, where the first line is used to render a message to the user take the input and store it into a userNUM variable.
  • Then the second line is used to check the user num value to be greater with the help of if statement.
  • Then the third statement is used to check the user num value to be equal with the help of elif statement.
  • Then the else statement will execute when the if and the elif statement will not true.
