2. Decay Constant, λ
- The fraction of atoms decaying in unit time
- The number of atoms decaying in unit time
- The frequency of atoms decaying in unit time
3. Lenz's Law
- The direction of the e.m.f. is such that it opposes the change causing it.
- The direction of the induced e.m.f. is such that it opposes the change causing it.
- The direction of the induced e.m.f. is such that it is in the same direction as the change causing it.
4. Isotopes
- Two nuclides (an atom with a distinct number of protons and neutrons) with the same number of protons but different numbers of neutrons
- Two nuclides (a nucleus with a distinct number of protons and neutrons) with the same number of protons but different numbers of neutrons
- Two nuclides (an atom with protons and neutrons) with the same number of protons but different numbers of neutrons
5. Magnetic Flux Density
- A measure of the strength of a magnetic field, defined by: B/ILsinθ, where B = magnetic flux density (T), I = current in the wire (A), l = length of the wire (m), F = the force experienced (N) and θ = the angle between the wire and the field.
- A measure of the strength of a electric field, defined by: B/ILsinθ, where B = magnetic flux density (T), I = current in the wire (A), l = length of the wire (m), F = the force experienced (N) and θ = the angle between the wire and the field.
- A measure of the strength of a magnetic field, defined by: BILsinθ, where B = magnetic flux density (T), I = current in the wire (A), l = length of the wire (m), F = the force experienced (N) and θ = the angle between the wire and the field.
