An infinitely long cylinder or radius R carries a uniform charge density of rho_0 C/m3. (a) Find the electric field in all of space and sketch the result. (b) For R=1.0 mm and rho_0= 1.0x10-6 C/m3, what is the value of the field at the surface of the charged cylinder? (c) What is the acceleration of an electron placed just above the surface of the cylinder? To solve the problem, consider a cylindrical Gaussian surface or radius r centered on the axis of the charged cylinder of unit length. ε0=8.854187817…x10-12 N m2/C2, e=1.6x10-19 C, me=9,11x10-31 kg

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

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”.
