PHYSICS 3

QuestionAnswer
WE CAN TRACE THE PATH OF ALPHA BETA GAMMA BY USING A.... CLOUD CHAMBER-
A CLOUD CHAMBER IS A ... SMALL TRANSPARENT CONTAINING AIR SATURATED WITH VAPOUR AND MADE VERY COLD. IONISING PARTICLE HAVE TO LEAVE A VISIBLE TRAIL OF LIQUID DROPLETS.
HOW WAS A POSITRON DISCOVERED ...IN 1932 CARL ANDERSON WAS USING A COLD CHAMBER AND A CAMERA TO PHOTOGRAPH TRAIL PRODUCE BY COSMIC RAYS. HE DISCOVERED A BETA PARTICLE THAT SLOWED DOWN BUT BENT IN THE OPP DIRECTION TO ALL THE OTHER BETA TRAILS. HE MADE A DISCOVERY OF A POSITRON THE FIRST ANTIPARTICLES DISCOVER.
WE CAN MEASURE FORCE USING... NEWTON METERS FORCE SENSORS.
WHEN SINGLE FORCE ACTS ON OBJECTS IT CHANGES... IT’S MOMENTUM. (MASS X VELOCITY).
WHEN 2 OBJECTS INTERACT THEY EXERT... EQUAL AND OPP FORCE ON EACH OTHER. MOMENTUM IS TRANSFERRED BETWEEN THE OBJECT BY THESES FORCES IF NO OTHER FORCES ACT ON THEM.
IF 2 PROTONS COLLIDE THEY... REPEL EACH OTHER AND MOVE WAY.
RICHARD FEYNMAN-USED A... EM FORCE BETWEEN CHARGE OBJECTS DUES TO VIRTUAL PHOTONS .
VIRTUAL BECAUSE .... WE CANNOT SELECT THEM DIRECTLY.
IF WE TRIED TO DETECT VIRTUALLY PROTONS ... THEM WE WOULD STOP THE EM FORCE ACTING.
THE VIRTUAL PHOTONS EXCHANGED... BETWEEN 2 PROTONS REPRESENTED BY A WAVE.
THE BALL TRANSFERS MOMENTUM FROM .... THE THROWER TO THE CATCHER AND THEY REPEL EACH OTHER.
THE EXCHANGE OF A VIRTUAL PHOTON.... BETWEEN 2 LIKED CHARGE PARTICLES HAS SAME EFFECT.AS THROWER AND CATCHER.
THE WEAK NUCLEAR FORCE THE STRONG NUCLEAR FORCE HOLDS THE.... NEUTRON AND PROTONS TOGETHER IN NUCLEUS .
BUT DOESN'T CAUSE THE NEUTRON TO CHANGE INTO PROTON IN BETA-) DECAY OR A PROTON TO CHANGE INTO NEUTRON IN BETA+) DECAY.
IN THE BETA+ AND – DECAY WHAT IS CREATED... A NEW PARTICLE AND NEW ANTIPARTICLE ARE CREATED IN EACH TYPE OF DECAY.
WHTA INTERACTIONS HAPPEN WITH ANTINEUTRINOS AND NEUTRINOS... RARALY HAPPENS BUT ,THE NEUTRINO CAN INTERACT WITH NEUTRINO AND MAKE IT CHANGE INTO A PROTON. A B- PARTICLE (AN ELECTRON ) IS CREATED AND EMITTED AS RESULT.
THE ANTINEUTRINO CAN INTERACT WITH... A PROTON AND MAKE IT CHANGE INTO NEUTRON. A BETA+ PARTICLE (POSITRON) IS CREATED AND EMITTED.
WHAT HAPS WHEN A NUETRINO INTERACT WITH NUETRINO ... MAKESNUETRINO CHANGE INTO PROTON. BETA – E.G. ELECTRON EMMITED.
WHAT CAUSES NUTRINO AND ANTINUETRINO INTERACTIONS ... DUE TO EXCHANGE OF PARTICLES REFERRED TO AS BOSONS W.
WHTA ARE BOSONS ... EXCAHNGE PARTCILES . THEY HAVE A NON XERO REST MASS.
WHTA IS THE REST MASS FOR X BOSON EXCHANGE PARTS/RANGE... NO ZERO REST MASS.
A SHORT RANGE NO MORE THAN 0.001FM. – ARE POS CHARGED (W+BOSON) OR NEG CHARGED (W- BOSON). CHARGE IS CONSERVED.
DISCOVERY OF W BOSON DETECTED USING ... DIRECTLY IN 1983 BY SCIENTIST USING 2KM DIAMETER SUPER PROTON SYNCHROTRON AT CERN.
PROTONS AND ANTIPROTONS AT VERY HIGH ENERGIES WERE MADE TO.... COLLIDE AND ANNIHILATE EACH OTHER. THESES ANNIHILATION EVENTS PRODUCED W BOSONS AND PHOTONS.
