What topic do Aerospace Engineers and Marine Engineers share as areas of knowledge necessary to perform their duties.

Fluid mechanics (dynamics)

Explanation:

The topic Aerospace Engineers and Marine Engineers has to do with the (common) environment of the equipment Aerospace Engineers and Marine Engineers work with which are air (gas) and water (liquid) both of which are classes of fluids

Therefore, the common topic shared by both professions is fluid mechanics which has branches of fluid statics (fluids at rest) , fluid kinematics (fluid having motion), fluid dynamics (the interaction of fluids in motion, and forces acting on them)

Given that both professions have energized equipment exerting forces in moving fluids, their common topic of knowledge is fluid dynamics

Fluid mechanics is a branch of physics, which is a branch of natural science which is one of the eight areas of knowledge.

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.
