The measurement of Hall voltage in the ‏سے‎ of Hall effect gives valuable information about
the :

(^^) Mobility of charge carriers (B) Structure of charge carriers
(C) Nature of charge carriers (D) Sign of charge carriers

By Debye approximation, the phonon heat capacity in the low temperature limit is :
(ಗಿ) Directly proportional to the absolute temperature

(8) Inversely proportional to the absolute temperature

(ल) Directly proportional to the square of absolute temperature

(12) Inversely proportional to the square of absolute temperature

Above Debye's temperalure, the ratio of thermal to electrical conductivities is directly
proportional to absolute temperature. This law was stated by :

(A} Wiedemann and Franz's (3) Lorentz and Drude
(C) Maxwell and Botlzmann (D) Rayleigh and Jean's

Superconducting Quantum Interferences Devices are used to detect :

(ಗಿ) High temperature in Ceramic Superconductor

(8) Cooper pairs tunneling through the Josephson junction

(८) Weak magnetic field produced by biological currents in the brain of living organisms
(10) Superconductivity at very low temperatures

The BCS theory accounts for a superconducting state formed from pairs of electrons
k Tand -k ‏.ل‎ These pairs will act as :

{^} Leptons (1) Bosons (C) Fermions (D) Hyperons

A standard man, who contains 18% of carbon, the micro curies of C'¥ present in a 80 kg man
is

The nuclear isomerism arises because of :

(A) the delayed emission of കുട by the nuclei

(B) the delayed emission ए B particles by the nuclei
(9) the interaction of B particles with y ray

(12) none of these
