Well, - i figured out the problem - the Ay is 0, since the block stays on the plane.

Homework Statement |\ |--\/\ |----\/ |-----\ Given inclined plane with mass M. The angle of inclination is Alpha (from the horizontal plane). The plane has no friction. On the plane block with mass m. The whole system is moving rightwards with acceleration A0. Find the N normal...

if you need the final answer - try online integral calculators. if you need steps - try to replace a/x with y and change the dx to dy

start with energy - select reference point - the bottom thus the energy at the top is M*G*H= 72 *G*120 the energy stays the same therefore MGH=MV^2/2 + Work of Friction and drag Work of Friction and drug = MGH - MV^2/2 I suppose the 4th task is simple to use W=F*X formula... otherwise...

cmos, thank you for your reply. With respect to propagating light through a lossy media. What would happen once beam of light is out of lossy media ? Would the phase variation return to zero or will it remain ?

DaleSpam, thank you for your response. If i may to elaborate the debate. Is it possible to create a phase variation in a beam of light. Say, we have a laser and with help of some instruments to change the phase between the fields of that laser ?

It is my understanding that for all of spectrum of light Electric and Magnetic fields have the same phase. And both fields have correlation - Magnetic fields amplitude grows along with Electric one. I am wandering - is it possible to generate light with phase shift between fields ?

It is hard to imagine anything today that runs without a computer... and software. Since most of software is operated by a person - it has to have some sort of Man Machine Interface. But not to mention the MMI , i imagine there has to be a lot of model programming and also some information...

Greetings to all, I was wandering - which languages are used for physics. And which fields in physics use software development heavily ? I am curious because, for the past 10 years i developed career in computer programming. But now days i am studying physics and soon will be faced with...

http://en.wikipedia.org/wiki/File:Right_hand_rule.png if you use that rule on your problem - than magnetic field ABOVE the conductor will be FROM the page. Whereas magnetic field BELOW the conductor will be INTO the page. Point B is BELOW conductor A and ABOVE conductor B. Therefore, Vectors of...

Dick, i loved your algorithm - very cool approach !:cool:

judging by your code, which is nasty, i think your task is number1 has to be EO number2 has to be EE product has to be OOOE Here is some code i wrote that does that. public class EvensOdds { public static void main (String[] args) { for (int num1 = 10; num1 < 100; num1++) { if...

can you give an example ? i didn't understand precisely what is the task. But maybe i can help.
