An electromagnetic wave strikes a 2.00-cm2 section of wall perpendicularly. The rms value of the wave's magnetic field is determined to be 5.00 10-4 T. How long does it take for the wave to deliver 1600 J of energy to the wall?

t=0.134 s

Explanation:

Given

Area of wall over which wave strikes

Intensity of Electromagnet wave is

where [/tex]c[/tex]=speed of light

=Permeability of free space

=RMS value of magnetic field

Average power is

time taken

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.
