Answer:

Inhalation and exhalation are how your body brings in oxygen and gets rid of carbon dioxide. The process gets help from a large dome-shaped muscle under your lungs called the diaphragm. When you breathe in, your diaphragm pulls downward, creating a vacuum that causes a rush of air into your lungs.

Explanation:

xD enjoy the answer hope it helps? :))

# 45 You are driving on a two-lane highway and the vehicle behind you wants to pass. You should
hram777 [196]

Answer:

Signal the driver behind you when it is safe to pass by turning on your four-way emergency flashers.

Avoiding casualties is the top priority when driving, the other choices given do not put whether there are cars in the other lane into consideration, therefore making them incorrect. Signaling the driver when it is safe gives you the time and them the gateway to pass, making a nice interaction keep you both alive.

A shaft made of stainless steel has an outside diameter of 42 mm and a wall thickness of 4 mm. Determine the maximum torque T th
fiasKO [112]

Answer:

Explanation:

Using equation of pure torsion

\frac{T}{I_{polar} }=\frac{t}{r}

where

T is the applied Torque

I_{polar} is polar moment of inertia of the shaft

t is the shear stress at a distance r from the center

r is distance from center

For a shaft with

D_{0} = Outer Diameter

D_{i} = Inner Diameter

I_{polar}=\frac{\pi (D_{o} ^{4}-D_{in} ^{4}) }{32}

Applying values in the above equation we get

I_{polar} =\frac{\pi(0.042^{4}-(0.042-.008)^{4})}{32}\\I_{polar}= 1.74 x 10^{-7} m^{4}

Thus from the equation of torsion we get

T=\frac{I_{polar} t}{r}

Applying values we get

T=\frac{1.74X10^{-7}X100X10^{6}  }{.021}

T =829.97Nm

Write code (ReverseNames.java) that prompts the user to enter his or her full name, then prints the name in reverse order (i.e.,
yan [13]

Answer:

import java.util.Scanner;

import java.io.*;

public class Main{

    public static void main(String []args){

       

       StringBuilder reversedName = new StringBuilder();

       StringBuilder subName = new StringBuilder();

       

       Scanner myObj = new Scanner(System.in);  // Create a Scanner object

       System.out.println("Enter your full name (last name + first name)");

   

       String name = myObj.nextLine();  // Read user input

       

       for (int i = 0; i < name.length(); i++) {

           

           char currentChar = name.charAt(i);

           

           if (currentChar != ' ') {

               subName.append(currentChar);

           } else {

               reversedName.insert(0, currentChar + subName.toString());

               subName.setLength(0);

           }

       }

       String Resul = reversedName.insert(0, subName.toString()).toString();

       System.out.println("Reverse full name: " + Resul);

    }

}

Explanation:

To solve the problem we used StringBuilder, that allow us to build a string letter by letter, we are using two, one to store temporary information (subName) and the other to store the surname plus name (reversedName). After defining the variables, the program asks for the user fullname using Scanner class and it's method .nextLine (the variable 'name' will save the user input). A while loop is also used to iterate over the name, taking character by character with the method .charAt, the program will append letters in subName until it finds a space only then the content of subName will be transfer to reversedName and the content of subName will be deleted, then the program continues with the process until the end of the for loop; finally, the program places the content of subName at the beginning of reversedName, and print the result transforming the StringBuilder to a normal string.
