Detailed Answers Graded A+|Assured Success
Binding energy - CORRECT ANSWER-The work that must be done to separate a nucleus into its
constituent protons and neutrons. Given by Δmc^2.
Mass defect - CORRECT ANSWER-The difference between the mass of the separated nucleons
and the mass of the nucleus. Symbol Δm.
, Binding energy per nucleon - CORRECT ANSWER-The average work that must be done to
separate a nucleus into its constituent protons and neutrons. The element with the largest value is iron.
Nucleon - CORRECT ANSWER-Proton or neutron.
Nuclear fission - CORRECT ANSWER-Process by which a large unstable nucleus splits into
fragments which are more stable than the original nucleus. The binding energy per nucleon increases in
this process. The fragments produced aren't the same each time.
Nuclear fusion - CORRECT ANSWER-Process by which small nuclei fuse together to form a
larger nucleus. The binding energy per nucleon increases in this process.
Induced fission - CORRECT ANSWER-Forcing a nucleus to undergo fission by bombarding it
with neutrons.
Line of force - CORRECT ANSWER-Direction a hypothetical "free north pole" would travel in
the field. Otherwise known as a field line.
Motor effect - CORRECT ANSWER-Effect in which a current in a magnetic field experiences a
force.
Fleming's left hand rule - CORRECT ANSWER-Way of working out the directions involved in the
motor effect.
Magnetic flux density - CORRECT ANSWER-Force per unit length per unit current on a
conductor perpendicular to the field lines. Often referred to as the strength of the magnetic field.
Couple - CORRECT ANSWER-Pair of forces in opposite directions that try to turn an object.
Acts on the coil of a motor.
