You have three light bulbs. All have the same intensity when lit. Explain how you can determine that they are connected in parallel by unscrewing one light bulb. In your response, state the relationship between the current and resistors in parallel.

Originally Answered: You have three light bulbs. ... A parallel circuit means that the current flows through all the loads (light bulbs in this question). Since the current is connected to each of them, disconnecting (unscrewing) one of them will still allow the current to flow to the other two and they will remain lit.

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 tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
