Feb 01, 2010 · The alkali silicate used was Grade D sodium silicate solution (Na 2 SiO 3) supplied by PQ Australia with a specific gravity of 1.53 and a modulus ratio (M s) equal to 2 (where M s = SiO 2 /Na 2 O, Na 2 O = 14.7% and SiO 2 = 29.4%). The hydroxide solution needed for activation was prepared to a concentration of 7.0 M using potassium hydroxide ...

7. A thin rod of mass M and length L spins clockwise with angular velocity ω about an axis that passes through one end of the rod, perpendicular to its length. An object of mass m moving to the left with velocity v strikes the rod at its midpoint and sticks to it. The rod stops spinning. What was v? (a) MLω 3m (b) MLω 6m (c) MLω 12m (d ...
