wind => external force

Newton third laws work on the different things.ex : when you kick the ball, the ball give you the same force as you kick the ball, see ,,, two differents things ! ball and your foot. while in your example you say that that laws work on the same stuff, other wrong example is the normal force vs...

parallel universe !

CMIIW isnt one of einstein postulate said that the speed of light is constant independent of the observer, or in other words the speed of light is just the same for any observer.

how about this http://mathworld.wolfram.com/"

wow nice one, never imagined that i could learn physics from youtube

so the light particle that come in will stay there ?? or what ?

electromagnetic field is a wave that consist a magnetic field and electric field that simultaneously spread . it once only the prediction of maxwell that predicted there was a relation between magnetic and electric field from the fact that each of them can create the other with the...

you should learn the unix like or maybe linux terminal , try ubuntu hehe btw for fast progress in java visit this site : http://download.oracle.com/javase/6/docs/"

in c++ #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int main() { int x; srand((unsigned) time(NULL)); x = (rand() %100) + 1; cout << x << endl; } x = (rand() %100) + 1 => you can change the "100" into any number you want to be the...

how about this ? http://mathworld.wolfram.com/"

maybe i can help since cos 60 = 1/2 , i'll use x as theta => cos x = cos 60 1. cos x = 60 + k.360 => x = 60 2. cos theta = -60 + k.360 => x = 300 in degree x = {60, 300} in radian x = {1/3 pi rad, 5/3 pi rad}

speed of light (c = 3 x 10^8) is an constant while on vacuum but c vary in other medium depend on its density. => n = c/v while n = refractive index. higher refractive index means less density. CMIIW

wow, thanks for your correction . so the only problem is because the image (.png) isn't in the class directory, isn't it ?

it always hard on the first time, start from the easy one . honestly I'm start from batch (.bat) hehe , go to python => Java => and now on C++. Actually I'm just learn python for getting the basic understanding about programming .. , once you get that basic you'll get the fun of programming language
