When the lights of a car are switched on, an ammeter in series withthem read 10.0A and a voltmeter connected across them (parallel)reads 12.0V. When the electric starting motor is turned on, the ammeter reading drops to 8.00 A and the lights dim somewhat. Ifthe internal resistance of the battery is .0500 Ohms and that ofthe ammeter is negligible what are the a) emf of the battery and b)the current through the starting motor when the lights areon?

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

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.
