(i will give you brainliest) a bodybuilder lifts a certain weight up and down. if the body builder does it in less time, which of these statements is most accurate?
a) the body builder uses both the same energy and power.
b) the body builder uses both more energy and more power.
c) the body builder uses the same energy and but more power.
d) the body builder uses the same power and but more energy.

students in a physical education class practiced rope climbing. students gripped a rope that hung from the ceiling and lifted themselves up the rope using only their arms. what must be measured to determine the power output of the climbers?
a) tension on the rope and the final height
b) body mass, final height, and the tension on the rope
c) tension on the rope and the time required to complete the climb
d) body mass, final height, and the time required to complete the climb

which of these would be the best definition of energy?
a) the ability to do work
b) the development of a future source of fuel
c) the feeling one gets from drinking caffeine
d) the feeling one feels after riding a roller coaster

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

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 !
