8.16 a 0.5 mhz antenna carried by an airplane flying over the ocean surface generates a wave that approaches the water surface in the form of a normally incident plane wave with an electric-field amplitude of 3,000 (v/m). seawater is characterized by r = 72, μr = 1, and σ = 4 (s/m). the plane is trying to communicate a message to a submarine submerged at a depth d belowthewater surface. if the submarine’s receiver requires a minimum signal amplitude of 0.01 (μv/m), what is the maximum depth d to which successful communication is still possible?

the correct answer is c.stops after infancy and childhood.

myelin is the substance of the central nervous system (cns) that insulates nerve cell axons to increase the speed at which nerve impulse travels. myelination is a process of myelin formation. this process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.
