I think you are confusing electron flow with current flow. This may help - http://amasci.com/miscon/speed.html so, current starts flowing right away.. and how many times it changes direction depends on the frequency. 50Hz would give you the answer where the current will change direction 50...

Hi, I am an undergrad student and for one of my courses I am required to model a mechanical / physical / electrical / thermal system that is a physical system (as in commonly used) and has a non linear oscillating behavior. if it is a mechanical system, it has to have mass, spring and...

thanks a lot.. it helped.

where i come from ( bangladesh, a country beside india) .. there it is a trend to study till 3 AM everyday.. students get that habit as they get into eighth grade and continue it till they graduate. but there the system is very different.. I thought in USA it would be different...

i am suffering from the same indecisiveness .. thanks a bunch guys for your help.. And I have heard that if one choses to major in Physics / EE, he has to forsake his social life.. I mean they allready have so much to do, they don't get any chance to go out there and do stuff.. Is...

Why cannot we see the future? You see, all the laws of relativity, quantum mechanics and the other physics interaction laws are time-reversible Then why cannot we see the future as well? I mean, when I look at the sky, I'm supposed to see ALL the stars that have zero-space-time-interval with...

please ignore my post.. that was a wrong window .. my bad, i apologize

Suppose O' is a frame that observes an infinite grid with all the clocks synchronized to O' itself. Now, O is a frame (me) who has a relative speed with respect to O' (thus all the other clocks of the grid as well) How will my observation of the times be affected by my motion...

sorry to be late to reply bro. according to wikipedia, this is the definition of metaphysics -

thanks a lot :D

can anybody help me to find the answer of this question? a fan ( or a propellor) rotates sidewise, but the air goes making a perpendicular with the axis of its motion.. I know that there is vector involved in this, but how does it work?

I have searched for the answer of this question for a long time... but did not get a satisfactory answer. what is fire? what is it made of?

I don't understand somethings. like the question never said u is high enough to be close to c ... if not, then will the clocks still show different times?
