Faraday's law {Ans: "The induced emf in a circuit is equal to the rate of change of flux linkage through the circuit".}Count rate {Ans: Number of counts per second.}Gravitational potential {Ans: Work done per unit mass to move a small object from infinity to that point}Equipotential {Ans: Line such that all points on the line require the same amount of work per coulomb for a point charge to be moved there from infinity - i.e. all points have the same potential.}Specific latent heat of vaporisation {Ans: Energy needed to evaporate a kilogram of a liquid at its boiling point with no change of temperature.}Cyclotron {Ans: Spiral particle accelerator.}Deposition {Ans: Process where a gas turns directly into a solid.}Magnetic flux linkage {Ans: Product of the magnetic flux and the number of turns of the coil.}Binding energy {Ans: The work that must be done to separate a nucleus into its constituent protons and neutrons. Given by Δmc^2.}Uniform {Ans: A field with constant field strength and parallel field lines.}Capacitance {Ans: Number of coulombs stored on a capacitor per volt of potential difference applied.}Solenoid {Ans: Electrical coil.}Half-life {Ans: Time taken for
