(a) With the aid of suitable diagrams
and examples explain the following terms:
(i)
surface tension
(ii) surface
free energy
(ii) surface
active agent (surfactant)
(iii) Krafft point
(i) With the aid of appropriate diagrams, explain why
indifference curves are traditionally convex to the origin.
(10%)
(ii) Given the indifference curve for two-goods is convex,
derive a price inelastic demand curve for Good X (10%)
(iii) With reference to the previous elements of this coursework
question, discuss the links between the indifference curve, price
elasticity estimates and the theory of supply and demand in
economics (80%).
28. Fluid Momentum problems are solved with the aid of two
diagrams of such problems. Explain, list or define items which
would be included on each of the two diagrams required, and
describe or show features common to both diagrams. Why are these
two drawings typically kept separate?
29. Propellers and turbines are similar in that both act as
screws. Attribute each of the following to Props, Turbines, or
Both:
a. __________Average velocity through the blades, (V1 +
V2)/2
b....
Explain, with aid of diagrams, the effects of an expansionary
fiscal policy under the classical theory and the Keynesian model.
Compare and contrast the effects under the two models. How would
these differences affect their conclusion on the role of
government? (20%)
Monetary and Fiscal
Policy:
Explain with the aid of diagrams, how
an increase in Government spending in a small open economy affects
the Aggregate Demand curve:
a. Assuming a flexible exchange
rate
b. Assuming a fixed exchange rate.
NO HANDWRITINGS PLEASE. I CAN'T READ MOST OF THE HANDWRITINGS,
UNFORTUNATELY. THANKS IN ADVANCE FOR TYPING ANSWERS
------An analog signal is sampled, quantized, and encoded into a
binary PCM wave. The number of representation levels used is 1024.
A synchronizing pulse is added at the end of each code word
representing a sample of the analog signal. The resulting PCM wave
is transmitted over a channel of bandwidth 24kHz using a 8
PAM system with raised-cosine spectrum. The rolloff factor
is 0.5.
(a) Find the rate (bit/s) at which information is transmitted
through the channel.
(b) Find...
