Answer: Distillation and Landfill
Explanation:
Distillation is the old method of water purification, these process involves the separation of compounds or components of a mixture based on their different boiling points. Today we have advanced method of seperation, although Distillation is still being used.
Land fill is one of the oldest form of waste disposal, these method involves digging up a large land mass(depending on the waste to be disposed) and dumping the water into the dugged land mass, then cover it up with the sand that was dugged out. Today, they are more advanced ways to handle wastes such as incinerator.
Answer:
The answer is "5.5 and 90.90%"
Explanation:
For point 1:
To calculate the speed from fast mode, its run time without enhancement should be worked out. Designers are aware of which two selves are implicated throughout the accelerated project planning: the empty (
) and the increased stages (
).
Although not enhanced, this would take almost as long (
) and for the combine to give phase; even so, the increased phase would've been 10 times longer, as well as
. Thus the corresponding total speed without enhancement is 
Its overall speed is:

For point 2:
We re-connect these figures in Amdahl's Law throughout order to identify how long it would take for both the initial implementation:

Answer:
The answer is A
Explanation:
Basically, Shortest job first (SJF) is a scheduling policy that selects jobs on queue for execution within a short execution time.
From the definition of SJF above, it means that there are a lot of process on queue and the (SJF) job is to receive processes on queue to execute within a short execution time.
Therefore, if all the jobs or process arrives at the SJF at the same time, the SJF will forfeit one of its major purpose which is scheduling of jobs.
That will therefore not make Non-preemptive Shortest Job First (SJF) not function at its optimal point.
