If E=mc2 then what does F equal?

Computers and Technology
1 answer:
Vladimir79 [104]2 years ago
4 0

Answer:

First of all,there is not theory F=ma^2!!

Its F=ma and they are definitely not the same.Here F means force and E means Energy.

a means acceleration, but c means the velocity of light. Clearly there's difference between acceleration and velocity and force and energy.

F=ma can be applied on things we normally see but E=mc^2 is applied on things that can travel nearly in light speed!which means atoms,molecules, protons,electrons etc. energy can be determined by the Einstein theory but F=ma is for determining human energy, or energy of cars,vehicles or any regular moving things

4.2.3: Basic while loop expression. Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Fol
wlad13 [49]

Answer:

import java.io.*;

import java.util.Scanner;

class divide {

public static void main (String[] args) {

    Scanner num=new Scanner(System.in);//scanner object.

    int userNum=num.nextInt();

    while(userNum>1)//while loop.

    {

        userNum/=2;//dividing the userNum.

        System.out.print(userNum+" ");//printing the userNum.

    }

}

}

Input:-

40

Output:-

20 10 5 2 1

Input:-

2

Output:-

1

Input:-

0

Output:-

No Output

Input:-

-1

Output:-

No Output.

Explanation:

In the program While loop is used.In the while loop it divides the userNum by 2 in each iteration and prints the value of userNum.The inputs and corresponding outputs are written in the answer.

In this lab, you complete a C++ program that swaps values stored in three int variables and determines maximum and minimum value
Sergio039 [100]

Answer:

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

int first = 0,second = 0,third = 0;//defining integer variable  

int temp; //defining integer variable

const string SENTINEL = "done"; // defining a string variable as constant  

string repeat;// defining a string variable  

bool notDone = true; //defining bool variable

cout << "Enter first number: ";//print message

cin >> first;//input value

cout << "Enter second number: ";//print message

cin >> second;//input value

cout << "Enter third number: ";//print message

cin >> third;//input value

while(notDone == true)//defining a loop to check the value  

{

if(first > second)//use if to compare first and second value

{

int temp = first;//defining temp to hold first value

first = second;//holding second value in first variable

second = temp;//holding temp value in second variable

}

if(second > third)//use if to compare second and third value

{

int temp = second;//defining temp to hold second value

second = third;//holding second value in third variable

third = temp;//holding temp value in third variable

}

cout << "Smallest: " << first << endl;//print smallest value

cout << "Next smallest: " << second << endl;//print Next smallest value

cout << "Largest: " << third << endl;////print Largest value

cout << "Enter any letter to continue or done to quit: ";//print message

cin >> repeat;//holding string value

if (repeat == SENTINEL)

{

notDone = false;//holding bool value

}  

else //else block

{

cout << "Enter first number: ";//print message

cin >> first;//input value

cout << "Enter second number: ";//print message

cin >> second;//input value

cout << "Enter third number: ";//print message

cin >> third;//input value

}

return 0;

}

}

Output:

Please find the attached file.

Explanation:

  • Inside the main method Four integer variable "first, second, third, and temp" is declared in which first three variable is used for input value and temp is used to compare value.
  • In thew next step, two string variable "SENTINEL and repeat" is declared in which "SENTINEL" is constant and a bool variable "notDone" is declared.
  • After input the value from the user-end a loop is declared that compare and swap value and print its value.

15. How many PC’s can be connected to a UPS?
Alex_Xolod [135]

Answer: Depends on the power of the computer /computers and the UPS

Explanation: For someone who had a big connected network of computers and printers we would plug the computer or server into the UPS as well as the monitor and sometimes a printer sometimes the monitor was plugged into the wall

When you get a UPS you must plug it in for a certain time could be hours or even a day.  A USP has a big battery in it and you must charge it (sometimes it comes semi-charged but you must plug it in to strengthen it. )

there are two connector wires that you affix to the battery and you must put a lot of strength into it to make it secure.

So in closing, you can get away with two like a desktop and a laptop.

Read your documentation that comes with the UPS
