Answer:

#include <stdio.h>

int main()

{

float afTest1[5] = {90, 30, 25, 45, 55};

for (int i = 0; i < 5; i++) {

printf("%f ", afTest1[i]);

}

return 0;

}

Explanation:

Initialize the elements of the array as 90, 30, 25, 45, 55

Create a for loop that iterates through the array

Inside the loop, print each element using printf function

Quired to the weight

expeople1 [14]

Answer:

The mechanical advantage is 0.25

This mechanical advantage shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.

Explanation:

Given;

output force, F₂ = 15 N

input force, F₁ = 60 N

Mechanical advantage also known as force ratio is defined as the ratio of the output force (load) to the ratio of input force (effort).

$M.A = \frac{0utput \ Force}{1nput \ Force} \\\\M.A = \frac{15 \ N}{60 \ N} \\\\M.A = 0.25$

This shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.

A. Calculate the diffusion coefficient for magnesium in aluminum at 450°C.

SIZIF [17.4K]

Answer:

a) D = 4.88 * 10^(-14) m^2 / s

b) t = 1.1 hr

Solution:

a) Magnesium in Aluminum diffusion:

D = Do * exp(-Qd / RT)

= (1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15)

= 4.88 * 10^(-14) m^2 / s

D = 4.88 * 10^(-14) m^2 / s

b) The composition remains same at say the distance Xo:

(Cx - Co) / (Cs - Co) = Constant

Xo^2 / D_{550} * t = Xo^2 / D_{450} * 15

D_{550} * t = D_{450} * 15

(1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15) * t

(4.88 * 10^(-14) m^2 / s) * 15

by, solving for t we get:

t = 1.1 hr

So, the time required is 1.1 hr.

A combination lock has the following basic properties:

fomenos

Answer:

public class CombinationLock {

private int combinationNumber1 = 0;

private int combinationNumber2 = 0;

private int combinationNumber3 = 0;

CombinationLock(int combinationNumber1, int combinationNumber2, int combinationNumber3){

this.combinationNumber1 = combinationNumber1;

this.combinationNumber2 = combinationNumber2;

this.combinationNumber3 = combinationNumber3;

}

public boolean open(int number1, int number2, int number3){

if(number1 == combinationNumber1 && number2 == combinationNumber2 && number3 == combinationNumber3)

return true;

else

return false;

}

public boolean changeCombo(int number1, int number2, int number3, int newNumber1, int newNumber2, int newNumber3){

if (open(number1, number2, number3)){

combinationNumber1 = newNumber1;

combinationNumber2 = newNumber2;

combinationNumber3 = newNumber3;

return true;

}else

return false;

}

Explanation:

- Three variables are created to hold the combination.

- A constructor is created to set the combination.

- A boolean method called open is created to check if the given numbers are correct, and returns true (otherwise returns false).

- A boolean method method called changeCombo is created to check if given numbers are correct. If they are correct, it assigns new values for the combination and returns true (otherwise returns false).

A diagram of a flow chart to find the average of 10 numbers

Nat2105 [25]

Answer:

Kindly check attached picture

Explanation:

Flowchart gives a graphical representation of a steps taken towers the execution of a program.

In the flowchart attached, A variable was initialized and set to 0 ; then a for loop was used to iterate integers 1 up to 10, for each number. It is added to the initialized variable sum until all the 10 integer numbers are added. The the average is obtained by dividing by 10.
