The internal resistance of a battery is relatively small when the battery is new but increases as the battery ages. When a new 12.0-VV battery is attached to a 100 ΩΩ load, the potential difference across the load is 11.9 VV. After the circuit has operated for a while, the potential difference across the load is 11.2 VV .By how much has the internal resistance of the battery changed?

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.

that the claims meet official rules.

don't misinterpret the claims
