Katen [24]

Answer:

The inability of the sinuses to drain and the associated lack of airflow create an environment that is ideal for bacterial growth. In acute viral sinusitis, the virus that caused the upper respiratory infection has infected the sinuses and continues to produce mucus, inflammation, and congestion.

A plate glass window (n = 1.5) has a thickness of 4.5 mm. how long does it take light to pass perpendicularly through the plate?
nirvana33 [79]

The solution to this is to use the n = c / v equation

Where:

c is the speed of light: 3x10^8; and

The idea that v = m/s

So plug in the m/s for v in the n = c v equation and you will get:

1.5 = (3 x 10 ^ 8)/ ((4.5m)/s))

Therefore, the time should be 2.25 x 10 ^ -10 seconds.

How do shale oil and tar sands compare to conventional<br> (regular) oil deposits?
konstantin123 [22]

Answer:

Oil shale is a form of sedimentary rock that contains kerogen, which is released as a petroleum-like liquid when the rock is heated. Tar sands are a combination of clay, sand, water and bitumen, which is a heavy hydrocarbon.

Additional info:

The term oil sands refers to a particular type of nonconventional oil deposit that is found throughout the world. Oil sands, sometimes referred to as tar sands, is a mixture of sand, clay, other minerals, water, and bitumen. The bitumen is a form of crude oil that can be separated out from the mixture.

The primary distinction between crude or conventional oil and shale oil is the way it collects. The oil in shale is typically found in smaller batches. As a result, shale oil often needs to be fractured so that the oil trapped within the shale can be recovered.
