Which formulas have been correctly rearranged to solve for radius? Check all that apply. r = StartFraction G times m Subscript central Baseline over v Superscript 2 Baseline EndFraction. r = StartFraction F Subscript c Baseline times m over v Superscript 2 Baseline EndFraction. r = StartFraction a Subscript c Baseline over v Superscript 2 Baseline EndFraction r = StartFraction v T Over 2 pi EndFraction r = StartFraction a Subscript c Baseline times T over pi EndFraction ITS A AND D

it would be a gas formation

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.
