Answer:

Re-torque the bolts as required while your engine is warm. But if you're using aluminum cylinder heads, you should wait until your engine is complete cooled until re-torquing

A circuit contains a 40 ohm resistor and a 60 ohms resistor connected in parallel. If you test this circuit with a DMM you shoul

lorasvet [3.4K]

<h2>Answer:</h2>

24Ω

<h2>Explanation:</h2>

When resistors are connected in parallel, the reciprocal of their combined resistance, when read with a DMM (Digital Multimeter - for measuring various properties of a circuit or circuit element such as resistance...) is the sum of the reciprocals of their individual resistances.

For example if two resistors of resistances R₁ and R₂ are connected together in parallel, the reciprocal of their combined resistance Rₓ is given by;

$\frac{1}{R_x}$ = $\frac{1}{R_1}$ + $\frac{1}{R_2}$

Solving for Rₓ gives;

$R_{x}$ = $\frac{R_1 * R_2}{R_1 + R_2}$ ------------------(i)

From the question;

Let

R₁ = resistance of first resistor = 40Ω

R₂ = resistance of second resistor = 60Ω

Now,

To get their combined or total resistance, Rₓ, substitute these values into equation (i) as follows;

$R_{x}$ = $\frac{40 * 60}{40 + 60}$

$R_{x}$ = $\frac{2400}{100}$

$R_{x}$ = 24 Ω

Therefore, the total resistance is 24Ω

Niobium has a BCC crystal structure, an atomic radius of 0.143 nm and an atomic weight of 92.91 g/mol. Calculate the theoretical

Olin [163]

Answer:

The theoretical density for Niobium is $1.87 g/cm^3$ .

Explanation:

Formula used :

$\rho=\frac{Z\times M}{N_{A}\times a^{3}}$

where,

$\rho$ = density of the unit cell

Z = number of atom in unit cell

M = atomic mass

$(N_{A})$ = Avogadro's number

a = edge length of unit cell

We have :

Z = 2 (BCC)

M = 92.91 g/mol ( Niobium)

Atomic radius for niobium = r = 0.143 nm

Edge length of the unit cell = a

r = 0.866 a (BCC unit cell)

$a=\frac{0.143 nm}{0.866}=0.165 nm=0.165 \times 10^{-7} cm$

$1 nm = 10^{-7} cm$

On substituting all the given values , we will get the value of 'a'.

$\rho=\frac{2\times 92.91}{6.022\times 10^{23} mol^{-1}\times (0.165 \times 10^{-7} cm)^{3}}$

$\rho =1.87 g/cm^3$

The theoretical density for Niobium is $1.87 g/cm^3$ .

Tech A says that serviceable wheel bearings can be repacked by removing the dust cap, filling it with grease, and reinstalling i

rewona [7]

Serviceable wheel bearings can be repacked by removing the dust cap and the cotter pin must be replaced with a new one every time it is removed. Therefore, both Tech A and B are correct.

Sealed bearing assemblies are typically prefilled with lubricant. They also make a more reliable and consistent installation process due to the fact that every into comes preset at the proper clearance.

Furthermore, the serviceable wheel bearings can be repacked by removing the dust cap, filling it with grease, and reinstalling it. Also, cotter pin must be replaced with a new one every time it is removed.

Therefore, both tech A and B are correct.

Given two input integers for an arrowhead and arrow body, print a right-facing arrow. Ex: If the input is 0 1, the output is

Lyrx [107]

For printing a right facing with input 01, define the class for right facing arrow and give the value with appropriate space using '%6d' and then display the right facing arrow.

Further Explanation:

The code to print the arrowhead and arrow body is as follows:

Import java.util.Scanner;

//Define the method.

public class RightfacingArrow

{

//Define the main method.

public static void main(String[] args)

{

//Create an object of Scanner class.

Scanner object = new Scanner(System.in);

//Declare the variables.

int baseChar;

int headChar;

//Prompt the user to enter the input values.

baseChar = object.nextInt();

headChar = object.nextInt();

//Display the headchar in position 6 from the starting.

System.out.printf("%6d ", headChar);

//Display the arrows.

System.out.println(baseChar+""+baseChar+""

+baseChar+""+baseChar+""+baseChar+""

+headChar+""+headChar);

System.out.println(baseChar+""+baseChar

+""+baseChar+""+baseChar+""+baseChar

+""+headChar+""+headChar+""+headChar);

System.out.println(baseChar+""+baseChar

+""+baseChar+""+baseChar+""

+baseChar+""+headChar+""+headChar);

//Display the headchar in position 6 from the starting.

System.out.printf("%6d ", headChar);

}

Output:

If the input is 01, the output will be as below:

0000011

00000111

0000011
