Which option most accurately defines Faraday’s law?

Any change in the electric field over a conductor will produce an magnetic field inside a conductor.
The voltage generated in a coil is inversely proportional to the number of electrons in the loop.
Any change in the magnetic field over a conductor will produce an electromotive force and electric current in the conductor.
The voltage generated in a coil is inversely proportional to the cross-sectional area of the coils loops.

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.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
