A series RC circuit contains two resistors and two capacitors. The resistors are 120 Ω and 470 Ω. The capacitors have capacitive reactances of 600 Ω and 300 Ω. When calculating the circuit values, what is the total capacitive reactance?

Total capacitive reactance=900Ω

Explanation:

Given data

The Capacitors Capacitive reactances

R₁=600Ω

R₂=300Ω

To find

Total capacitive reactance

Solution

In series circuit total capacitive reactance is sum of individual capacitors capacitive reactances

So

Total capacitive reactance=R₁+R₂

Total capacitive reactance=(600Ω )+(300Ω )

Total capacitive reactance=900Ω

i don't know that i agree with that but what's the question ?

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.
