Rami is designing an experiment to study how the stored energy in an object affects its energy in motion. Which statement best describes why Rami should be careful about writing down his experimental procedure and results? The experiment can be changed by others to get different results.
The procedure and results can teach others how to do an experiment.
The exact experiment can be repeated by others, and the results can be compared.
The results will help compare the mechanical energy in different objects.

Explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
