Answer:
With the use of API.
Explanation:
The computer system is an electronic device that comprises of the interaction of the hardware and software components of its system. The software component of the system controls all activities of the hardware and other application software interface.
The operating system is that software in the system that controls all system activities. It uses the kernel interface to connect directly to the hardware and create a platform for running application or user softwares.
The user software is used to run one specific task on the system. Sometimes, it seeks to kernel mode from the operating system, to use a hardware component, by the use of API or application program interface.
Answer:
A power supply tester is specifically designed to test DC voltage on most connectors coming from a PC power supply. A multimeter measures electrical properties such as voltage, amps, and resistance.
Answer:
1. Modified formulae for calculating tree height.
.
2. C++ program to calculate tree height.
#include<iostream>
#include<math.h>
using namespace std;
int
main ()
{
double treeHeight, shadowLenghth, angleElevation;
cout << "Please enter angle of elevation and shadow length" << endl;
cin >> angleElevation;
cin >> shadowLenghth;
//Modified formulae to calculate tree height.
treeHeight = tan (angleElevation) * shadowLenghth;
cout << "Height of tree is:" << treeHeight;
}
Output:
Please enter angle of elevation and shadow length
45
12
Height of tree is:19.4373
Explanation:
Since no programming language is mentioned, so solution is provided using C++.
In the above C++ program, first angle of elevation and length of shadow provided by user will be stored in variables angleElevation and shadowLength.
Then using the modified formalue height of tree will be calculated and stored in variable treeHeight. Final result is displayed to user.

Assuming you need to write a program that has "Karel put down a tennis ball if the world has dimensions of 1x1," the control structure you should use is: C. If Statement.
<h3>The types of control structure.</h3>
In Computer programming, there are different types of control structure and these include the following:
- For Loop
- While Loop
- If/Else Statement
- If Statement
<h3>What is an if statement?</h3>
An if statement can be defined as a conditional statement that is written by a computer programmer to handle decisions by running a different set of statements, depending on whether an expression is either true or false.
