Answer:

The major effects of ice accretion on the aircraft is that it disturbs the flow of air and effects the aircraft's performance.

Explanation:

The ice accretion effects the longitudinal stability of an aircraft as:

1. The accumulation of ice on the tail of an aircraft results in the reduction the longitudinal stability and the elevator's efficacy.

2. When the flap is deflected at $10^{\circ}$ with no power there is an increase in the longitudinal velocity.

3. When the angle of attack is higher close to the stall where separation occurs in the early stages of flow, the effect of ice accretion are of importance.

4. When the situation involves no flap at reduced power setting results in the decrease in aircraft's longitudinal stability an increase in change in coefficient of pitching moment with attack angle.

In a right triangle, the square of the length of one side is equal to the sum of the squares of the lengths of the other two sid

Dovator [93]

Answer:

C++ code is explained below

Explanation:

/Remove the following line

//if not using visual studio.

#include "stdafx.h"

//Import the required header files.

#include <iostream>

using namespace std;

//Define the main function.

int main(void)

{

//Define the variables.

double side1, side2, side3;

//Prompt the user to enter the sides of the triangle.

cout << "Enter the side of the triangle:" << endl;

cout << "Enter first side of triangle:" << endl;

cin >> side1;

cout << "Enter second side of triangle:" << endl;

cin >> side2;

cout << "Enter third side of triangle:" << endl;

cin >> side3;

cout << endl;

//Check if the triangle sides are valid

if ((side1 + side2 > side3) &&

(side1 + side3 > side2) &&

(side2 + side3 > side1))

{

//Check the condition for right angle triangle

if ((side3*side3 == (side1*side1 + side2*side2)) ||

(side2*side2 == (side3*side3 + side1*side1)) ||

(side1*side1 == (side3*side3 + side2*side2)))

//Display that the triangle is right-angled triangle.

cout << "It is a right-angled triangle." << endl;

else

//Display that the triangle is not the right-//angled triangle.

cout << "It is not a right-angled triangle."

<< endl;

}

else

//Display not the valid side.

cout << "Not a valid side." << endl;

//Remove the following line if

//not using visual studio.

system("pause");

return 0;

At the beginning of last year, tarind corporation budgeted $1,000,000 of fixed manufacturing overhead and chose a denominator le

maxonik [38]

The tari's total standard machine-hours allowed for last year's output 600,000 hours

Budgeted at start of year: $100,000 fixed manufacturing overhead for 500,000 machine hours

Standard = $100,000 / 500,000 hours = $0.2 fixed overhead / maching hour

At end of year, manufacturing overhead volume was $20,000 favorable which means

$20000 / $1=0.2 = 100000 additional hours.

Total Standard Machine Allowance Allowed for output = 500,000 + 100,000 = 600,000 hours.

the use of one machine running for an hour as a basis for cost estimation and operating effectiveness evaluation. In order to determine the contribution margin per machine hour for a specific product: a. Total cost per unit divided by the quantity of machine hours required to produce each unit of the target product. The manufacturing overhead cost divided by the activity driver yields the predetermined overhead rate. For instance, if machine hours were the activity driver, you would divide overhead costs by the anticipated number of machine hours.
