Suppose a current flows through a copper wire. Which TWO things occur? O A. An electric field forms around the wire.
B. The field is parallel to the direction of flow of the current.
C. The field is perpendicular to the direction of flow of the current.
D. A magnetic field forms around the wire.

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

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.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
