As mentioned above I'm unable to begin because I don't know the relevant equations or method.

I have a belief from something I read on the internet that the superscript 1 means that this is a singlet state so it can only hold one particle but then say 3^S_0 is a triplet so it could hold three. Then the first state I mentioned couldn't have a particle and an antiparticle in it , but the...

I'm working on some stuff for particle physics and I had a few questions I wanted to ask . Heres the outline of the problem : Establish which initial states of the ppbar system amongst 1^S_0, 3^S_1, 1^P_1, 3^P_0, 3^P_1, 3^P_2, 1^D_2, 3^D_1, 3^D_2, 3^D_3 the reaction ppbar->npi^0 can...

oh I think I get it now so what your saying is although I could find axb and get the answer I got first , I could just as easily choose bxa as they're both the same but have opposite signs and so it still satisfies the proof.

when I calculated the components I got axb = ( cosθi +sinθj )x(cosΦi + sinΦj) axb=cosθcosΦixi + cosθsinΦixj +sinθcosΦjxi +sinθsinΦjxj ixi=1x1xsino=0 jxjxsin0=0 ixj=1x1sin90=1 and jxi=-1 because AxB=-BxA and was then left with axb= cosθsinΦ(1) + sinθcosΦ(-1)=cosθsinΦ -sinθcosΦ but...

Homework Statement given two unit vectors a= cosθi + sinθi b=cosΦi+sinΦj prove that sin(θ-Φ)=sinθcosΦ-cosΦsinθ using vector algebra[/B]Homework Equations sin(θ-Φ)=sinθcosΦ-cosΦsinθ[/B]The Attempt at a Solution axb= (cosθsinΦ-cosΦsinθ)k and I'm guessing that the change in sign has...

I just realized of course displacement is also a vector, which was pretty silly of me still any help with the actual question would be much appreciated

Homework Statement at what initial speed would a projectile have to start at when ejected at 35 degrees to the horizontal from a point A to a point B which is 9.4km distance away in the horizontal and 3.3km below it. taking g as 10m/s[/B]Homework Equations I'm not really sure if these equations...
