Suppose i produce radio waves with an antenna that have a peak electric field amplitude e and peak magnetic field amplitude b. if i were to double the amplitude of the electric field (i. e. double e) what is the new value for b? b b/4 b/2 zero 2b 4b

Correct answer is 2B

Explanation:

The electric field magnitude and magnetic field magnitude in an electromagnetic waves are related as under

where 'c' is velocity of light in the medium of transmission

According to the given question if we double the electric field we have

Thus the magnetic field also doubles

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

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.
