In young's experiment, coherent light passing through two slits separated by a distanced produces a pattern of dark and bright areas on a distant screen. if instead you use 10 slits, each the same distance d from its neighbor, how does the pattern change? a) the bright areas move farther apart 2. c) the spacing between bright areas remains the same, but the bright areas become narrower. d) the spacing between bright areas remains the same, but the bright areas become broader. b) the bright areas move closer together

answer; (arch); good luck

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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 !
