Answer:

Parallelogram law of vector addition states that if two vectors are considered to be the adjacent sides of a parallelogram, then the resultant of the two vectors is given by the vector that is diagonal passing through the point of contact of two vectors.

A controlled process is described by the closed-loop transfer function G(s).

MissTica

Answer:

The answer is "Option B".

Explanation:

Given equation:

$G(s) =\frac{K(s + 1)}{2s^2 + (K-1)s + (K-1)}\\\\$

$\to 2s^2 + (K-1)s + (K-1)=0$

Calculating by the Routh's Hurwitz table:

$\to s^2 \ \ \ \ \ 2 \ \ \ \ \ \ K-1 \\\\\to s^2 \ \ \ \ \ K-1 \ \ \ \ \ \ \\\\\to s^0 \ \ ( \frac{(K-1)(K-1)(-2) (0)}{K-1} \\\\ \ \ \ \ = (K-1) )$

Form the above table:

$\to K-1 > 0 \\\\ \to K > 1$

In the above, the value of k is greater than 1.

The separation and purification process is used for which of the following purposes?

Svetach [21]

The separation and purification process is used for DEVELOPING VACCINES. The development of vaccines must follow strict guidelines.

A vaccine is a biological preparation used to protect against harmful diseases (e.g., viruses) in a simple and safe manner.

Vaccine purification is a strict process consisting of clarification, concentration and chromatography in order to separate the extract that contains the active principle of the vaccine.

The techniques used for vaccine filtration include membrane filtration, depth filtration and centrifugation.

when electric power is transmitted over long distance, line losses can be reduced by generating AC rather than DC voltage and by

Tanya [424]

When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.

<h3>What is electric power?</h3>

The complete question is attached to the image below.

The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.

The AC transmitted is of high voltage, and the power is low. The equation for current is given,

P = VI

The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.

Therefore, the loss is reduced by transferring high voltage and, low current AC.

Write a class having two private variables and one-member function which will return the area of the rectangle.

Yuri [45]

Using the knowledge in computational language in C++ it is possible to write the code being write a class having two private variables

<h3>Writting the code in C++:</h3>

#include <iostream>

using namespace std;

class Rectangle { /*create a class named Rectangle*/

private:

float l,b; /*this class has two private variables l and b*/

public:

float getArea(float l, float b) /*this class has one member-function getArea which returns the area of the rectangle*/

{

return l*b; /*return the area of the rectangle*/

}

};

int main () { /*the main function to check the working of our Rectangle class*/

float l,b;

Rectangle r1; /*create an object r1 of Rectangle class*/

cout<<"Enter the length of the rectangle: ";

cin>>l; /*input the length of the rectangle from the user*/

cout<<"Enter the breadth of the rectangle: ";

cin>>b; /*input the breadth of the rectangle from the user*/

cout <<"Area of the rectangle is: "<< r1.getArea(l,b)<<" square units."; /*find the area of the rectangle using the member function of the class*/

return 0;

}
