WebApr 11, 2024 · Moreover, from Fig. 2(c), one can find that the conduction band and valence band of K′ ↓ are linearly connected; in other words, the Dirac point appears. In fact, according to the equation of the dispersion relation (8) , when λ ν = λ ω , the position of the Dirac point appears when E = E F − h 0 is satisfied.

WebThe density of a rod ABincreases linearly from Ato B. Its midpoint is Oand its centre of mass is at C. Four axes pass through A,B,Oand C, all perpendicular to the length of the rod. The moments of inertia of the rod about these axes are IA , IB , IO , and IC respectively. This question has multiple correct options MEDIUM View Answer WebDec 9, 2024 · Correct Answer is: (a, b, c, & d) As all three particles are part of the system, any impact between them produces no change in the velocity of their centre of mass. Also, ‘A + B’ can exert a force on B only along the rod, i.e., normal to u. ← Prev Question Next Question → Find MCQs & Mock Test Free JEE Main Mock Test Free NEET Mock Test reason for smoking jacket
