This diagram shows that Al can see the reflections of Ed and Fred in the mirror. Which two students can both see the reflections of Cy, Di, Ed and Fred? *
A)Bo and Cy
B)Cy and Di
C)Di and Ed
D)Ed and Fred

B) Cy and Di

Explanation:

Reflection is the process in which a ray of light is sent back along its path on hitting a plane surface. This ensure that the measure of angle of incidence is equal to that of reflection. Mirrors generally have a high reflecting capacity, thus its various applications.

From the diagram by ray construction,

i. Cy would see Cy, Di, Ed, and Fred

ii. Di would see Cy, Di, Ed, and Fred

Thus, it can be inferred that both Cy and Di would see the reflections of Cy, Di, Ed, and Fred from the mirror because of their locations.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
