Is it possible for a city to be located at 120 degrees south and 30 degrees west? explain

Not possible

Explanation:

It is not possible for a city to be located at 120° S and 30° W. It is because the earth is equally divided into into two hemispheres, where the latitudes starts from 0° at equator to 90° at poles, and the longitudes starts from 0° to 180° measuring from east to west direction or west to east direction.

Thus, no place can exist beyond 90° in both the hemisphere.

i would say b

explanation:

but i think i would need more information than that

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.
