A long straight wire is carrying a constant current I in the z-direction. At time t=0, an electron is in the z=0 plane and at a distance r = r◦ the wire. Assuming that the electron starts with equal parallel and perpendicular components of velocity v⊥ = vk, calculate the magnitude and direction of grad-B drift velocity.

What happens when molecules diffuse across a membrane? Molecules move across a membrane from the area with the greater total molecule density to an area with less molecule density. Water flowing through the pores in a membrane washes solute molecules from one side of the membrane to the other. The random motion of molecules ultimately produces equal concentrations of molecules on both sides of a membrane. Active transport of molecules against their concentration gradient evens out the number of molecules on either side of a membrane.

Top management is very concerned about the unprofitable divisions (I and II). Consensus is that one or both of the divisions should be discontinued. (a) Compute the contribution margin for Divisions I and II. (Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).)
