QuestionAnswer
ACCELERATORS: - THE TV TUBE IS AN ACCELERATOR BECAUSE.... IT ACCELERATES ELECTRONS THROUGH PD OF ABOUT 500V.
THE ELECTRONS FROM A BEAM, WHICH HIT THE INSIDE OF TV SCREEN. MAGNETIC FIELDS PRODUCED BY ELECTROMAGNETS DEFLECT THE BEAMS SO IT CAN SCAN THE SCREEN TO CREATE IMAGE.
THE LONGEST ACCELERATOR IN THE WORLD IN... THE STANFORD LINEAR ACCELERATOR IN CALIFORNIA.
THE BIGGEST ACCELERATOR IN THE WORLD IS ... THE LARGE HADRON COLLIDER AT CERN GENEVA –
LHC IS DESIGNED TO ACCELERATE.... CHARGE PARTICLES TO ENERGIES MORE THAN 7000GEV. 27KM CIRCUMFERENCE RING CONSTRUCTED IN CIRCULAR TUNNEL BELOW THE GROUND.
PROTONS , NEUTRONS , PI MESONS AND K MESONS ARE ALL EXAMPLES OF... PARTICLES WE CALL HADRONS BECAUSE THEY EXPERIENCE A STRONG INTERACTION .
HADRONS PARTICLES EXPERIENCE... A STRONG NUCLEAR INTERACTION
NUETRION WHICH IS ONE TYPE OF HADRON ... BECAUSE EXPERINCES STRONG NUECLEAR FORCE, DOESN;T DECAYS INTO OTHER PARTICLES.
CHARGE PI PARTICLES PRODUCED IN PAIRS LEADING TO CONCLUSION THAT... PI POS MESONS AND PI NEG MESONS ARE A PARTICLE ANTIPARTICLE PAIR. THE SAME CONCLUSION FOR K MESONS.
THE SYMBOLS FOR THE ANTIPROTON ANTINEUTRON AND ANTINEUTRINO IS... THE SYMBOL WITH A BAR ON TOP APART FROM THE ANTIMUON AND POSITRON.
WE CAN DIVIDE THEM INTO 2 GROUPS CALLED... HADRONS AND LEPTONS.
THE 2 HADRON LEPTONS GRPS ARE ACCORDING TO... WHETHER OR NOT THEY INTERACTION THROUGH THE STRONG INTERACTION.
HADRONS ARE ... PARTICLES AND ANTIPARTICLES – THAT CAN INTERACT THROUGH STRONG INTERACTION
EXAMPLES OF HADRONS INTERACTION THROUGH STRONG INTERACTION ... (E.G. POSITRONS , NEUTRONS , PI MESONS AND K MESON.
LEPTONS ARE.... PARTICLES AND ANTIPARTICLE THAT DO NOT INTERACT THROUGH THE STRONG INTERACTION.
EXAMPLES OF LEPTON THAT DECAYS THROUGH WEAK INTERACTION ... ELECTRON , MUON AND NEUTRINOS.
LEPTONS INTERACT THROUGH ... THE WEAK INTERACTION AND THROUGH THE EM INTERACTIONS IF CHARGED.
WHTA ELSE CAN LEPTON INTERACT IN ... EM INTERCATION IF CHARGED.SAME FOR HADRONS
WEIGT OF LEPTONS... LIGHT AND WEAK ,
HAWEIGHT OF HADRONS... STRONG AND HEAVY.
FIXED MAGNETS ALL THE WAY ROUND THE RING IN THE LHC BEND... THE PATH OF THE PARTICLES TO KEEP THEM IN THE RING.
WHEN PARTICLES COLLIDE IN LHC THE TOTAL ENERGY... OF THE PARTICLES AND ANTIPARTICLES BEFORE THE COLLISION= THE REST ENERGY + THE KINETIC ENERGY.
THE TOTAL ENERGY OF THE NEW PARTICLE AND ANTIPARTICLES AFTER THE COLLISION =... THEIR REST ENERGY + THE KINETIC ENERGY.
THE REST ENERGY OF PRODUCTS =. . TOTAL ENERGY BEFORE - THE TOTAL ENERGY OF THE PRODUCTS. E.G. IS AN PROTON AND A ANTI PROTON COLLIDE WITH KINETIC ENERGY 2GEV . 1GEV= 1000MEV.
K MESON ARE CREATED WHAT PRODUCED .... SHORT LIVED PARTICLES WITH GREATER REST MASSES THAN PROTON PRODUCED. PARTICLE CREATED THROUGH STRONG INTERACTION SO THEY ARE HADRONS. THEY DECAY INTO PROTONS AND PI MESON.
WHEREAS PROTONS ARE NEVER AMONG THE DECAY PRODUCTS OF... K MESONS
