First off i will start with a question. When the mass of the Earth was found was the mass of the current population taken into account? If so then technically as the years progress and population increases the mass of Earth would increase. If the population was not taken into account shouldn't...
Create a program in which the digits returned are reversed such as if 234 was the input the output is 432.
import java.util.*;
public class Test{
public static void main(String[] args){
String revNum ="";
int rem = 0;
int n...
you can use the equation P1/T1 = P2/T2 where P1 is initial pressure and T1 is initial Temperature and P2 is final pressure and T2 is final temperature.
at that point you should plug into get rid of sin and cos so you are working with decimals and just follow order of operations. if you have a graphing calculator it would make life much easier but if not just plug and chug and go step by step as to not lose anything.
first you are going to want to split your velocity up into components even though you don't know what v is you can still end up with two V with different coefficients and then you can put those into your equations and then solve through use of simultaneous equations.
I personally find that i rarely use
FInal velocity ^2 = initial velocity ^2 + (2 * acceleration * displacement) since its only used when you do not have a time and are solving for something else but with the other two you can pretty much solve for anything and even if you think you can't you...
The coefficient of kinetic energy is the constant for which friction is acting as a retarding force to show how much force is actually being applied on the object through the equation F= mu * N where mu is the variable that stands for the coefficient of kinetic energy. there is also a shortcut...
Homework Statement
Find the force(F) needed to move a 50kg box up a ramp angled at 40 degrees with an acceleration of 1m/(s^2) while pulling at an angle of15 degrees above parallel to the ramp. the ramp has a frictional constant of .1
a=1m/(s^2)
m=50kg
angle of ramp=40 degrees
angle...
In addition we also use a site called Javabats and i was wondering if there were any better sites similar to it or any feedback on how useful javabats is would be nice.
You are going in the right direction by finding PEelastic. By doing this you also found KE since KE=PEelastic so from there you just plug it into the equation.
I am currently taking a computer science II class in high school, in which we use java, and my teacher does not really know how to go about teaching and when she tries to help usually makes things worse. Does anyone know of any sites to help teach/reinforce the java language?
