Two materials are separated by an interface, describe the
boundary conditions that connect the electric and magnetic fields
generated from one material to the other.
Create a configuration consists of two different mediums to
describe the boundary conditions and specify how the tangential and
normal components of the electric fields in one medium are related
to the components in other medium across the boundary.
Describe the boundary lines for two- variable
inequalities. Why are the boundary lines for two- variable
inequalities with greater than and less represented by dotted
lines? Provide examples.
First, define a boundary line and tell where it comes from. Then,
describe what the boundary line can tell us about solutions to an
inequality. You can also talk about how to know what part of a
graph to shade. Finally , talk about the cases where we use each
type of...
Which statement correctly describes mirror symmetry boundary
conditions in thermal analysis?
A. Symmetry boundary conditions require definition of convection
coefficient on the faces in the plane of symmetry
B. Symmetry boundary conditions can’t be used if conduction is
modeled
C. Symmetry boundary conditions do not apply to thermal
analysis
D. No thermal condition must be defined on faces in the plane of
symmetry
For a unique solution to the wave equation, what boundary
conditions must be satisfied.
a) Boundary conditions are not needed for a medium with no
interfaces.
b) This is a trick question; all boundary conditions must be
satisfied.
c) The tangential boundary conditions
d) The normal boundary conditions
e) Continuity in solution across the boundary must be
satisfied.
T F (1)The loss tangent is related to the ratio of the
conduction current density to the convection current density in the...
Two electric charges, the first value + 3Q and the second value
+ 2Q are separated by a known distance d. What load and at what
distance from the first load should be placed a third collinear
load with the other two, for the three load system is in
balance?
Why is is useful to enforce the separation of interface from
implementation (i.e., the abstraction
boundary) of an ADT? Provide a concrete example to help
justify your explanation
Consider a two-dimensional electron gas in a square box of side
L, with periodic boundary conditions.
a) Derive the density of states per unit energy, D(ε).
b) Find the Fermi wavevector, kF, and the Fermi

the area of the box, A=L2 .
c) Calculate the density of states at the Fermi energy,
D(εF), expressed in terms of N and A. Calculate the heat
capacity, CV.
