Two skydivers jump out of a plane. Both skydivers jump when the plane is traveling at 200 m/s and is 3800 meters above the ground. One skydiver is 70 kg, the other is 60 kg. Scientists want to observe if the mass of a skydiver affects the motion of
the skydiver as he or she travels through the air.
Which would be the independent variable?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

Energy defines the different "states" of matter. in no more than 3 sentences, describe the amount of kinetic energy that each of the 3 states of matter possesses and relate that to the atom/molecular motion of each "state".
