Answer / debshree

ANSWER 1 IS CORRECT

Answer / vinay upadhyay

answer (d) is correct . because here change of tempr is depend on characteristic length of object and according to ques characteristic length of each will same so their gainig of 90% of tempr difference will requires same time . tou =row *characteristic length*heat capacity /heat transfer cofficient

Answer / vas

answer 1 (cube) is correct since temp change depends on few
factors, one of which is footage (S) of contact between the
body and substance. Among other equal factors the footage
is different. Thus, the only problem for us here is to find
out solution how to compare footages of the bodies we have.
Since we know that their weights are equal and know the
formulas for figuring out their weights, we will find soon
that the smallest S belongs to the cube, consequently the
biggest belongs to the sphere.

ENGINEERING PHYSICS - EXAMPLE 30.4 : (a) Time evolution in Heisenberg picture, according to Ehrenfest theorem is m (d / dt) < r > = < p >, where m = mass, r = position, p = momentum of a particle. If v = velocity, prove that m < v > = < p >. (b) Lande g-factor is given by Gj = Gl [ J (J + 1) - S (S + 1) + L (L + 1) ] / [ 2J (J + 1) ] + Gs [ J (J + 1) + S (S + 1) - L (L + 1) ] / [ 2J (J + 1) ]. If Gl = 1 and under approximation of Gs = 2, prove by calculation that Gj = (3/2) + [ S (S + 1) - L (L + 1) ] / [ 2J (J + 1) ].
