A localized source (such as an antenna, for example) is radiating electromagnetic waves outward in all directions. Far away from the source, at 8.5 km away, the intensity of the EM wave is measured to be 43 μW/m2. What is the peak value of the magnetic field of that EM wave at that location? (in T)

The magnetic field is 6.00 × 10^-10 T or 0.60 nT

increase masses, decrease separation

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.
