It is to think in terms of two basic kinds of change: piecemeal and systemic. piecemeal change leaves the structure of a system unchanged. it often involves finding better ways to meet the same needs, such as using an analogy to your students learn the science concepts you taught in an otherwise similar manner last year. in contrast, systemic change entails modifying the structure of a system, usually in response to new needs. references: reigeluth, c. m. (1999). what is instructional-design theory and how is it changing?

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
