For this activity, you'll analyze the motion of the marked spot on the skateboarder's leg. For each dropdown labeled “cm” or “model cm,” change the option to “Legs.” In each frame containing a plot or table, you can use the buttons at the top of the frame to choose whether it shows a plot (graph) or a table. If it is showing a plot, you can select the y-axis label to choose which measurement to plot. See how to change the graph and table options.

Now look at the graphs for the horizontal and vertical displacement of the legs against time.

How do the two graphs, x vs. t and y vs. t appear? What can you say about the displacement of the snowboarder?

i think the answer would be reserve.

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 !

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
