If the magnetic field in a traveling EM wave has a peak value of 17.9nT, what is the peak value of the electric field strength?

Doss [256]

Answer:

5.37 N/C

Explanation:

Peak value of magnetic field, Bo = 17.9 nT = 17.9 x 10^-9 T

The electromagnetic wave is produced when an oscillating electric and magnetic field interacts each other perpendicularly.

The direction of propagation of electromagnetic wave is perpendicular to both electric and magnetic field.

the relation between the electric field and magnetic field amplitudes is given by

$c = \frac{E_{0}}{B_{0}}$

where, c be the velocity of light, Eo be the peak value of electric field strength, Bo is the peak value of magnetic field strength.

$3\times 10^{8} = \frac{E_{0}}{17.9\times 10^{-9}}}$

Eo = 5.37 N/C

What could damage the eardrum and bones of the middle ear?

klio [65]

Answer:

B or D

Explanation:

I wanna say B but I don't really know if it's a trick question

my explanation for D is that anvils are usually 110 decibles and ear drums usually are damaged when exposed to 82dbs or higher at a consistant rate so I'd imagine that'd be the answer I hoped this helped
