The susceptibility of diamagnets is always negative. True or False 17. The susceptibility of paramagnets is always positive. True or False. 18. It is possible to float a frog in air if one applies a sufficiently strong field.True or False 19. Barium Titanate is a ferroelectric. In a unit cell of this crystal, the Ti ions are of 4e' where displaced relative to the oxygen i ons by 0.006 mm. The charge of this dipole 'e' is the charge of single electron. What is the dipole moment in terms of e" 20. The capacitance of a plane-parallel ca in vacuum is C EoAd, where A is the area of the plate and D is the separation between the plates; ge is the permittivity of vacuum. True or False increasing order are as follows: Metals, 21. The materials with lowest to highest resistivity, in semiconductors, and insulators. True or False False 22. The n-type semiconductors have holes as the primary charge carriers. True or 23. Silicon is an intrinsic semiconductor. charge carriers 24. Mobility of a charge carrier is a measure of frequency with which the experiences scattering. True or False electron per atom. If there are N 25. Copper is a monovalent metal with a single 4s valence the valence band. How atoms in a bar of solid, how many states are available in many states are empty.

Explanation / Answer

10. True

Because the magnitic field (B) is directly proportional to the magnitic field strength (H).

B = uH

u is permeability
