2) fluorine (f), boron (b), and lithium (li) are all in the same period, but are in different groups,
higher electronegativity than boron, which has a higher electronegativity than lithium (f = 398,
0.98. however, boron has a higher melting point than both fluorine and thum, and thym's
m
higher than that of fluorine (f = -220°c, b = 2300°c, - 180°c)
200,-

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.
