Suppose you are conducting an experiment concerning gravity's effects on falling objects, and you want to minimize air resistance. Which of these would be the MOST useful and practical way to do this? A) Use larger objects B) Use extremely dense objects, Conduct the experiment underwater. D) Conduct the experiment at various altitudes,

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
