Answer:

see down -

Explanation:

a ) Computer is an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.

b ) A reason is that people wanted better and efficient calculating devices. This started from the abacus to ENIAC and UNIVAC. Also, modern computers work on the principle of input-process-output and George Boole's logic.

c ) A weakness of a computer is that it isn't so open-minded like human brains. They can't make logical answers and created to give a specific set of answers. They also can't read real human emotions.

d ) Full form of CCTV is Closed Circuit Television. Full form of MRI is Magnetic Resonance Imaging.

Give 5 stars and Brainliest if I am correct on all answers.

Draw a circuit with a 12-volt battery, a 100 ohms resistor in series, and two resistors (each of value 200 ohms) in parallel. Wh
amid [387]

Answer:

200 Ω

Explanation:

Hi there!

Please see below for the circuit diagram.

<u>1) Find the total resistance of the resistors in parallel</u>

Total resistance in parallel equation: \frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2}

Both the resistors measure 200 Ω. Plug these into the equation as R₁ and R₂:

\frac{1}{R_T} = \frac{1}{200} +\frac{1}{200}\\\frac{1}{R_T} = \frac{1}{100}\\R_T=100

Therefore, the total resistance of the resistors in parallel is 100 Ω.

<u>2) Find the total resistance of the circuit</u>

Now, to find the total resistance of the circuit, we must add the 100 Ω we just solved for and the 100 Ω for the other resistor placed in series:

100 Ω + 100 Ω = 200 Ω

Therefore, the total resistance of the circuit is 200 Ω.

I hope this helps!

Sauron [17]

Answer:

import java.util.Scanner;

public class num8 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter first number");

       int X = in.nextInt();

       System.out.println("Enter second number");

       int Y = in.nextInt();

       int Z;

       if(X <= Y){

           Z = 0;

       }

       else if(X >= Y){

           Z = 1;

       }

   }

}

Explanation:

  • The program is implemented in Java
  • In order to set the values for X and Y, The Scanner class is used to receive and store the values in the variables (Although the questions says you should assume these values are set)
  • The if conditional statement is used to assign values (either 0 or 1) to variable Z as required by the question.
