Answer:
- import java.util.Scanner;
- public class TryToParseDouble {
-
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- double num;
-
- try{
- System.out.print("Input a number: ");
- num = Double.parseDouble(input.nextLine());
-
- }catch(NumberFormatException e){
- num = 0;
- System.out.println("Invalid input! It should be a number in double type");
- }
- System.out.println(num);
- }
- }
Explanation:
Firstly, create a Scanner object to get user input (Line 5).
Next, create a try block and prompt user to input a number and use Double.parseDouble() method to convert the input to double type in the block (Line 8-10).
Next, create a catch block to catch a NumberFormatException. In the Catch block, set the num to zero and then print out a message to inform user about the invalid input (Line 12-14).
Lastly, display the number (Line 16).
Assuming V1 is the anode and v2 the cathode (Anode is P region and Cathode is N)
Answer:
a) Reverse bias
b) Forward bias
c) Forward bias
Explanation:
Forward bias: It happens whenever the N region of the diode is more positive than the P region. Hence, the depletion zone increase ceasing the current through the circuit -> V1 -V2 < 0
Reverse bias: It happens whenever the P region of the diode is more positive than the N region. In this case, the depletion zone begins to shrink, if enough voltage is applied current could go through the circuit -> V1 - V2 > 0
a) V = V1 - V2 = 0 - 2 = -2 -> -2 is smaller than zero therefore, we have reverse bias
b) V = V1 - V2 = 4.5 - 2.8 = 1.7 -> 1.7 is greater than zero therefore, we have forward bias
c9 V = V1 - V2 = -1 - -1.3 = 0.3 -> 0.3 is greater than zero therefore, we have forward bias
Answer:
by receiving personal calls you can be fired from job
Answer:
a) 0.35 W
b) 5.25 W
Explanation:
Given that
Width of the chip, W = 5 mm
The environment temperature, T(∞) = 15° C
Surface temperature, T(s) = 85° C
The initial convection heat coefficient, h1 = 200 W/m².K
The final convection heat coefficient, h2 = 3000 W/m².K
See attachment for solution
Answer:
Left arm because the driver seat is on the left, so it would be easier, and safer, to use your left arm.
But, if you live in an area in which the driver seat is on the <em>right</em>, then it would be the right arm.
