Which of the following best describes the efficiency of dry scrubbers at removing particles that are less than 2 micrometers in

diameter? Dry scrubbers are less than 20% efficient at removing particles less than 1μm and increase to over 50% efficiency at removing particles between 1 and 2μm. A Dry scrubbers are between 50% and 90% efficient at removing particles less than 2μm, depending on the flow rate. B Dry scrubbers are between 5% and 40% efficient at removing particles less than 2μm in size. C Dry scrubbers are less than 10% efficient at removing particles less than 1μm in size.

Answer: dry scrubbers are less than 10% efficient at removing particles less than 1μm in size

Explanation:

A dry scrubber or dry scrubber system is one type of scrubber that is used to remove harmful materials from industrial exhaust gases before they are released into the environment. That substance then falls out of the gas stream or is caught in a particle screen.

Light waves are transmitted across the ________ and enter the eye through the ________.
alexdok [17]

Light waves are transmitted across the cornea and enter the eyes through the pupil.

<h3>FURTHER EXPLANATION</h3>

The eyes and the brain are important in helping people see. Light passes through the eyes and this light gets transformed into electrical signals which are sent to the brain that helps make sense of the object that is seen.

<h3 /><h3>How People See</h3>
  1. Light is incident on an object (or strikes an object). Some of it get absorbed, some are reflected into a human's eye.
  2. Light that bounces off the object is transmitted across the cornea,  the transparent outer layer of the eye. It refracts the light and makes things look sharp and clear.
  3. Then the light enters the pupil which is the opening in the eye controlled by the iris or the colored part of the eye. The iris changes the size of the pupil and controls the amount of light that enters the eye. When there is bright light, the pupil becomes smaller. In dim light, the opposite happens and the pupil becomes bigger.
  4. At the back of the pupil is the lens which again helps focus the light. Its shape changes depending on the distances of the objects that is being looked at.
  5. The light rays are focused by the lens so that they all converge in the retina which is at the back of the eye. The retina has many specialized cells which are sensitive to light. These cells transform light energy into electrical signals or nerve impulses which form a rough inverted image of the object the person is looking at.
  6. The electrical signals travel to the brain through the optic nerve. The brain turns the image upright and adds more detail to the vision.
