Any ideas ?

Hi guys ! Im trying to get my head round precession, nutation and spin. Suppose I have a cylinder of height L, base radius R. Initially it is just spinning about its central axis (i.e. line joining cone tip to the centre of base). In this scenario, centripetal acceleration experienced by say...

any ideas folks ?

Exams This Week...need Help Please ! hi guys ! good 2c every1 again..been a while..ive got my 3rd year uni exams..and it aint lookin good...can ne1 help me with this one ? Homework Statement An inertial observer sees a particle moving at a speed 3c/5..Its then seen to decay into 2...

Hmmm..interesting

A thought just occurred to me.We have made so many scientific discoveries over centuries.Many physicists believe that in 50 years time there won't be anything else left that needs to be discovered.What if what we think about things is wrong ?.After all we fix frames of references,we define...

Thanks mate ! that was exactly my mistake.I can't believe I made that error :cry: but oh well !. :rolleyes: Cheers again ! This world needs more people like :approve: you

Oh by the way,i used the equation : dL=h/mc (1-cos angle) and i got dL=2.43 E -12 Since the energy reduction is 1 % i did hc/L-hc/L' =0.01 and L'=L+2.43 E -12 so we end up with a quadratic : L^2 - (2.43 E -12)L-(4.83 E -35)=0 Solving I got, L= O or -2.43 E -12 Hence...

Any ideas how to do this question ? In a Compton type experiment X-rays scattered through 90 degrees suffered one percent reduction in energy.What was the incident energy of the X-rays ? You can assume that the electron coiled non-relativistically. Any help would be really appreciated ...

Thats a brilliant point there hypnagogue ! I never thought of that.If there was a law giver,then how did he come into existence in the first place ?.Boy ! this is amazing isn't it ?.It almost ends the argument as to whether there is a law giver or not. Suppose there was a law giver then.Then...

We are all human beings on a planet called earth.Many things happened on this planet which resulted in atoms : the basic structural unit of matter to combine to form what we call 'life'.Not many planets were lucky to see this happen.But different kinds of atomic combinations took place to form...

Well as far as Physics is concerned in India we did a bit almost everything.There are no classifications like astrophyiscs,nuclear physics etc..All students aspiring to be doctors or engineers/scientists had to do physics and it included the basics of all branches of Physics : Mechanics,Nuclear...

Stage-1 is nothing but Year-1.Most students here go straight to Stage-1 after completing their A-Levels.But I decided to start from Stage-0 which is basically a kind of Foundation Year where we did basic Maths,Physics and Computing[like how to use search engines and go to a website and stuff lol...

Hi there,I am Dave's coursemate as well.We are in Stage-1. I am doing a BSc in Astronomy With Astrophysics [hopefully].The softwares we use now are Transmath and Maple both which are not that hardcore.

I am still here,still busy at uni registering and stuff.Hope I'll be free soon to contribute !
