A0.250 kg lump of clay is dropped from a height of 1.15 m onto the floor. it sticks to the floor and does not bounce.

a force versus time graph. the force f is plotted along the vertical axis and the time t is plotted along the horizontal axis. the force is zero except over a second interval. over the interval of nonzero force, the force versus time curve takes the shape of an isosceles triangle with a value of f equals f subscript max at its apex.

what is the magnitude of the impulse imparted to the clay by the floor during the impact?

=.002375 kg⋅m/s
the force exerted by the floor on the clay is plotted as a function of time in the figure. what must have been the maximum force max exerted by the floor on the clay?

statement #3 on andre"s list is false.

answerscientific theory;

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 !
