Base units - Answer✔Units that define the SI system:
Kg
Amp
S
M
Beta radiation - Answer✔when B- or B+ particles are emitted following decay of a neutron-rich
or proton-rich nucleus
Breaking stress/Ultimate tensile stress - Answer✔Tensile stress needed to break a solid material
Brittle - Answer✔Snaps without bending or stretching when subject to stress
Centre of mass - Answer✔Point through which a single force on the body has no turning affect
Charge carriers - Answer✔Charged particles that move through substance when PD applied
across it
Kirchoff's 1st Law - Answer✔Current passing through 2 or more components in series is the
same through each component
At a junction the total current in = total current out
Kirchoff's 2 Law - Answer✔2 or more components in series - total PD across all the components
is = to sum of the PD's across each component

Sum of emf's around complete loop = sum of PD's around the loop
Coherent - Answer✔Constant phase difference and same frequency
Conservation rules - Answer✔Rule that:
Baryon no
Lepton no
Charge
Energy
Momentum
always conserved in interactions
When is strangeness conserved? - Answer✔Strong interactions
How are strange particles created? - Answer✔Strong interactions
How to strange particles decay? - Answer✔Weak interactions
Couple - Answer✔Pair of equal and opposite forces acting upon the same body but not along
the same line
Critical angle - Answer✔The angle of incidence of a light ray must exceed this angle for total
internal reflection to occur
Critical temperature - Answer✔Temperature at or below which a superconducting material has
zero resistivity
