Nuclear Physics 0.0 / 5 ? PhysicsParticle physicsASAQA Created by: NikitaSunuwarCreated on: 07-06-18 18:34 What is Specific Charge? Charge to mass ratio of a particle 1 of 31 what is the range for the strong nuclear force? 0.5fm - 3fm 2 of 31 what distance causes the strong nuclear force to be attractive? > 0.5fm 3 of 31 what does the strong nuclear force do? holds the nucleus together 4 of 31 what happens at B- decay? electron and antineutrino are released and neutron turns into a proton in a "neutron rich" nucleus 5 of 31 what does the antineutrino do in B- decay? carries some energy and momentum 6 of 31 what are photons? packets of EM radiation 7 of 31 what is pair production? when particle - antiparticle pair is produced from a single photon. hf=2E 8 of 31 what is annihilation? when particle and antiparticle meet, all the mass gets converted to energy hf=E 9 of 31 what are forces caused by? particle exchange 10 of 31 why are forces caused by particle exchange? you can't have instantaneous action at a distance 11 of 31 what is the proper name for exchange particles? Bosons 12 of 31 what are the 4 fundamental forces? electromagnetic, weak, strong and gravity 13 of 31 what's the gauge boson for electromagnetic force? virtual photon 14 of 31 what's the gauge boson for strong nuclear force? gluon 15 of 31 what's the gauge boson for weak nuclear force? W+/W- or Z 16 of 31 what's the gauge boson for gravity? graviton 17 of 31 what group of particles are the only ones that can feel the strong nuclear force? Hadrons 18 of 31 what happens in electron capture? proton turns into a neutron, releases W+ boson which converts e- to V. 19 of 31 what are hadrons made of? quarks 20 of 31 what is the only stable baryon? proton 21 of 31 what's the baryon number for anti baryons? -1 22 of 31 what do kaons decay into? pions 23 of 31 what interaction do leptons interact with other particles through? weak, gravity and electromagnetic 24 of 31 what do muons decay into? electrons 25 of 31 what is the only interaction neutrinos can take part in? Weak 26 of 31 give an example of a strange particle Kaons - created through strong but decay via the weak 27 of 31 what interaction is strangeness always conserved in? strong 28 of 31 what's the purpose of the weak interaction? causes decay by changing quark type 29 of 31 what's always conserved in particle interactions? Charge, Baryon number, Energy and Momentum 30 of 31 is there such thing as a free quark? no, this is quark confinement 31 of 31
