If r1 =1 ω, r2 =2 ω, r3 = 6 ω, r4= 6 ω, r5= 0.5 ω, r6= 2 ω, r7= 4 ω, r8=6 ω, r9=4 ω, r10=6 ω, r11=3 ω, r12=4 ω, r13=6 ω, r14=6 ω, r15=6 ω, r16=6 ω, and r17=3 ω, and v=15v, calculate the currents and voltages through it each resistor.

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.
