A loop of wire is placed in a perpendicular magnetic field. Suddenly, the magnitude of the magnetic field begins to increase, what is the direction of the induced current in the loop

As the bar moves upward through the constant magnet

ic field region, the area of the loop decreases, so

the flux through the loop

decreases. By Lenz’s law, any induced current will

tend to oppose the decrease. Using right hand rule

we know that magnetic field

inside the loop due to a ccw current comes out of t

he plane. Therefore a ccw current will create a str

onger magnetic field inside

the loop, tending to increase the flux.

Explanation:

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.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
