State Newton’s second law of motion. Show that Newton’s first and third laws of motion are contained in the second law

mixer [17]

Answer:

Every physics student learns Newton's three laws of motion. It's tempting to consider that these are three separate and independent laws. That's not so. Both the first and third laws may be mathematically derived from the second law, as we will show.

The fact that the first law may be derived from the second has long been known. The second law,Fnet=ma, tells us that the net (vector sum) of all forces acting on a body is equal to the product of the body's mass and its vector acceleration. When the acceleration is zero, the net force must be zero. This is exactly the content of the first law.

Let's first consider the case of two bodies in contact. Each exerts a force on the other at the interface, or point of contact, where the bodies touch. If that point or interface is treated as a "body" of mass zero, then Newton's second law tells us thatFnet=0a, soFnet= 0. So the net force on a body of zero mass is always zero, whatever forces act upon it. Therefore if only two forces act on a body, they must add to zero, and therefore must be equal size and oppositely directed. This establishes Newton's third law.

Main topics: Basic Java program

bazaltina [42]

Answer:

Explanation:

import java.util.Scanner;

public class pitcherValues {

public static void main(String[] args) {

String firstName, lastName;

int earnedRuns, inningsPitched;

double ERA;

Scanner in = new Scanner(System.in);

System.out.println("Pitchers First Name is?");

firstName = in.nextLine();

System.out.println("Pitchers Last Name is?");

lastName = in.nextLine();

System.out.println("How many runs did the Pitcher earn?");

earnedRuns = in.nextInt();

System.out.println("How many innings did the Pitcher Pitch?");

inningsPitched = in.nextInt();

ERA = (earnedRuns * 9) / inningsPitched;

System.out.println(firstName + " " + lastName + " has an ERA of " + ERA);

2.Write an if /else if statement that carries out the following logic. If the value of variable quantityOnHand is equal to 0, di

Oliga [24]

Answer:

if(quantityOnHand == 0) { cout<<"Out of stock"; }

else if(quantityOnHand > 0 && quantityOnHand <10) { cout<<"Reorder "; }

else if(quantityOnHand >= 10){ }

See Explanation for comments

Explanation:

//This program segment is written in C++

//Only required segment is written

// Comments are used for explanatory purpose

// Program Segment starts here

The following condition tests if quantityOnHand equals 0

If this condition is true, the program prints "Out of stock" without the quotes

if(quantityOnHand == 0) { cout<<"Out of stock"; }

The following condition tests if quantityOnHand is greater than 0, but less than 10

If this condition is true, the program prints "Reorder " without the quotes

else if(quantityOnHand > 0 && quantityOnHand <10) { cout<<"Reorder "; }

The following condition tests if quantityOnHand is greater than o equal to 10

If this condition is true, nothing is done

else if(quantityOnHand >= 10){ }

// End of program segment

Assumption: <em>The program assumes that variable </em>quantityOnHand has already been declared
