Its just a convention man..more applicable for bigger numbers...like you can write 10000000 or 10^7 they would mean the same thing...its just for the ease of writing

anyone?moderators?please help.

well what I'm actually looking for is practical variations with conditions.I'm building a project which works on collisions n so i want to know for how long will my original calculations be valid and what all variations will occur with time.still,i appreciate your response.

Homework Statement On what all factors does coefficient of restitution depend?i mean do we have 1 for a pair of surfaces in contact or a surface has one irrespective of the surface of the other colliding body?Also,practically,does coefficient of restitution change/vary?If yes,could anyone...

Homework Statement How do cars accelerate? Homework Equations f=ma The Attempt at a Solution the only external force on a car is friction,generally forward directioned for the back wheels n backward directioned for the front ones.when a car accelerates how is this friction varied...

how do you define an idealistic situation here?i mean,lets say instead of a single electron, i have a beam of electrons..doesnt that work as a better approxiamtion? in that case doesn't your 2nd argument fail? as much as I've infered from this discussion is, that basically are you trying to...

could you elaborate a bit on this?

as far as I've read,potential energy of a current carrying loop in a uniform magnnetic field is U=-p.B where p,B are magnetic dipole moment vector of the loop and the magnetic field vector(the field already present) the tendency of a current carrying loop should have been to align itself WITH...

Homework Statement CONSIDER A SITUATION AN ELECTRON SAY MOVING ON THE SCREEN OF UR COMPUTER FROM BOTTOM TO TOP . SUDDENLY A MAGNETIC FIELD IS SWITCHED ON OUTWARDS TOWARDS YOUR FACE FROM THE SCREEN . NOW VISUALISE THE MOTION OF ELECTRON SURELY A ANTI CLOCKWISE CIRCLE { AN ELECTRON IS...

2.3 degrees or 78 degrees? like civil said,it can be calculated..just check again.

an approximate solution is possible through pt of intersection of the 2 graphs...but i don't think there's any way to find an exact solution save hit n trial

Where do I start?! Hi! I'm a freshman at IIT(Indian Institute of Technology,Delhi)with a mechanical engineering major.Apart from my love for mechanical engineering,I'm also pretty inquistive about Quantum physics,Cosmology n stuff...The problem is that my college does not allow for a minor...
