Acurrent runs through a wire in the +y direction along the y-axis. what is the direction of the magnetic field at a point (x, y,z) = (0,0,1.045 m)

Magnetic field at given point is along + x direction

Explanation:

As we know that position of the wire is along Y axis

current is flowing along +y direction

so here we will have

now the direction of length vector is along +Y direction

also the position vector is given as

now for the direction of magnetic field we can say

so magnetic field is along +X direction

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.
