Two point charges are 10.0 cm apart and have charges of 2.0 uC and -2.0 uC respectively. What is the magnitude of the electric field at the midpoint between the two charges?

asthenosphere and convection

iron would move it is magnetic there is a mag field around the current in the wire

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

it was given as a lesson and guide for prayer.
