A plane wave traveling through vacuum in the z direction encounters a perfect conductor occupying the region z ≥ 0, and reflects back: E(z, t) = E0 [cos(kz − ωt) − cos(kz + ωt)] ˆx, (z < 0). Requried:
a. Find the accompanying magnetic field (in the region z < 0).
b. Assuming B = 0 inside the conductor, find the current K on the surface z = 0, by invoking the appropriate boundary condition.
c. Find the magnetic force per unit area on the surface, and compare its time average with the expected radiation pressure.

the plateau is likely to turn into a desert do to corrosion.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
