In class the formula fnt1 = . - (1+g) fr " was presented. In it n represents the stage of + 1+ gf, enrichment, fn represents the fraction of the total that is the lighter of the two components (eg. 235U) at the nth stage of enrichment, and g represents the additional probability that a nucleus of the lighter type goes to the next stage as compared to a nucleus of the heavier type. In this problem we will work through how "iterating" such an expression works. For simplicity assume that in our initial input we have equal numbers of the two types so fo=.5. Let us assume we have discovered a very efficient method of enrichment for the lighter particles are twice as likely as the heavier ones to go to the next stage go g=1. Find the fat the next four stages, that is find f 1,f2,f 3 and f4.

Select the correct answer from each drop-down menu. compared to its surroundings, the concentration of solutes is low inside a cell. so, the cell is with respect to its surroundings. a particular solute in this cell uses energy for its transport from the cell to its surroundings. this type of transport is called

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

Can anybody me with this? ? (picture included.)
