Three 12.0Ω resistors are connected in series with a 15.0 V battery. Find the following.
(a) the equivalent resistance of thecircuit
1 Ω

(b) the current in each resistor
2 A

(c) Repeat for the case in which all three resistors are connectedin parallel across the battery.
equivalent resistance 3 Ω
current in each resistor 4 A

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.

0.11 m/s and 0.28 m/s should be correct

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.
