A coil consisting of 100 circular loops with radius 0.60 m carries a 5.0A current. (a) Find the magnetic field at a point along the axis of the coil 0.80 m form the center (b) Along the axis, at what distance from the center of the coil is the field magnitude 1/8 as great as it is at the center?

the bal will not change its velocity.

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.
