Question

Assuming equal ion temperature, the square of a form of this quantity is proportional to T over n-q-squared. TIRF·M exploits the low value of this quantity achieved by the evanescent wave. Fritz and Heinz London name a form of this quantity (20[1])that describes magnetic fields in superconductors. A small value for this quantity, denoted delta, describes an (0[1])exponential decay in alternating current density due to eddies in the (*) skin effect. (0[1])The decrease in electric field (0[1])strength with this quantity due to screening is described by two forms of this quantity named for Thomas (0[1])and Fermi and for Debye. This (0[1])quantity (10[1])is squared in the denominator of Coulomb's (10[1])law. (10[1])For 10 (10[1])points, name this quantity (10[1])measured in microns or meters. (10[2])■END■ (10[3])

ANSWER: length [accept distance or depth or penetration depth or radius; accept Debye length or Debye radius or Debye–Hückel screening length or London penetration depth or skin depth or Thomas–Fermi length; prompt on r or lambda-sub-D] (The lead-in describes the Debye length.)
