1)Please construct the framework of the physics which you have learned in the
past half semester(starting from the simple harmonic oscillator). (30%)
2)What is the eigen mode? Use two coupled oscillators as an example. How do
you extend this concept to explain the elastic wave on a string? (10%)
3) (15%)
a)Interpret the physical signficiance of the following terms:
i)charge, ii)electric field, iii)divergence
b)What is Gauss law, in the integration and the differential forms? What is
the relation with Coulomb's law?
c)What is the significance of ε_0 (epsilon zero)?
4)An infinite cylinder at diameter d is uniformly charged with charge density
ρ. Determine the electric field as a function of radius r. (10%)
5)What are the conditions for a system under which the system can be treated
as a thermodynamics system? What are the spatial and temporal scales? (10%)
6) (15%)
a)What is the "micro-state" for a thermal system? What is the "macro-state"?
Please give a few examples. What is entropy?
b)What is the postulate of equal apriori? What is the second law of thermal
dynamics? What is the relation between the postulate of equal apriori and
the second law of thermal dynamics?
7) (10%)
a)What is the zero-th law of thermal dynamics. Please explain it from the
statistical point of view.
b)What is the physical significance of temperature?
8)An idea gas at temperature T expands isothermally from the initial volume Vi
and pressure Pi to the final volume Vf, please calculate the total work done
and the heat transfer in the whole process. (10%)
9)Describe and explain the motion of a rolling coin on a flat horizontal
surface from beginning till it falls. (原PO註:此題是期中考題)
