Two soil samples fully saturated were collected from the field for testing in the lab, both having a natural void ratio of 0.6. The composition of the soil particles is as follows:
Sample 1: Composed of ONLY quartz [3]
Sample 2: Composed of 65% quartz, 23% mica &12% iron oxide.
[4] The average value of specific gravity of soil particles is 2.65 for quartz, 3.0 for mica and
3.8 for iron oxide. Calculate the total unit weight of soil mass and specific gravity of soil particles for both the above mentioned soil samples.

Climate change is a daunting problem facing humanity today. One way to mitigate this problem in the construction industry is to "build green". Green buildings have many benefits, but their initial cost is mostly higher that conventional buildings. In your opinion, should Green Star certification be made a mandatory requirement for all new developments (both residential and non-residential) in Australia? How could this be achieved?

Explain in detail why is coordination required at all phases of construction for MEP systems? What are the outcomes when a job is not coordinated properly? Why is in important to coordinate at time of bid and what are the downsides to coordinating at the time of bid? Your response should include references to all MEP systems discussed during the semester.

The motion of a 16.1 lb. particle is given by:
r(ϴ) = (5sin 2ϴ) ft, with ϴ(t) = πt/4 rad,
and t in seconds.
Determine the magnitudes of the particle’s position, velocity, acceleration, linear momentum, net force, and T (K.E.) at t = 2 s.
