Breaking stress/Ultimate tensile stress -CORRECT ANSWER-Tensile stress needed to break a
solid material
Brittle -CORRECT ANSWER-Snaps without bending or stretching when subject to stress
Centre of mass -CORRECT ANSWER-Point through which a single force on the body has no
turning affect

applied across it
Kirchoff's 1st Law -CORRECT 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 -CORRECT 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
