A soil has a natural water content of 10%, specific gravity of
2.65, and porosity of 0.45.
a) Find the dry unit weight and degree of saturation.
b) If the optimum water content for the soil from a standard
proctor was 20%, how much water would have to be added to 1m^3 of
the soil to increase the water content to an optimum level?
1 a) How is density , specific gravity and specific weight
related to each other? Write formula and specify SI units for each
of these terms.
1 b) How does density, vapour pressure and viscosity change with
temperature and how do you explain these changes ?
What are 7 or more key ways in which marketers (in hotels and
other companies) could actively and effectively engage with
TripAdvisor? One way to answer this question is to assume that you
are the CEO of a hotel and your TripAdvisor ratings at below 2
(where 5 is the best). What specific strategic initiatives would
you as the CEO pursue to address this situation?
The appeal of using multiple departmental overhead rates is that
they presumably provide a more accurate accounting of the costs
caused by jobs.

Compare the Ptolemaic and Copernican models. Explain in what
ways each was an accurate model of the universe, and in what ways
each was inaccurate. Describe retrograde planetary motion of the
inner and outer planets and how those models explained it.
