An infinite plate is moved over a second plate on a layer of liquid as shown. for small gap width h=0.3mm, we assume a linear velocity distribution in the liquid with speed v=0.3m/s. the liquid viscosity is 0.65 centipoise and its specific gravity is 0.88. determine: (a) the absolute viscosity of the liquid, in lbf. s/ft2. (b) the kinematic viscosity of the liquid, in m2/s. (c) the shear stress on the upper plate, in lbf/ft2. (d) the shear stress on the lower plate, in pa. (e) the direction of each shear stress calculated in parts (c) and (d). data: linear velocity profile in the liquid between infinite parallel plates as shown. μ = 0.65 cp sg = 0.88

explanation:

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
