1.For cubic crystals, as values of the planar indices h, k, and l increase, does the distance between adjacent and parallel planes (i.e., the interplanar spacing) increase or decrease? Why?
2.Compare the crystalline state in metals and polymers. (b) Compare the noncrystalline state as it applies to polymers and ceramic glasses
3.Offer an explanation as to why covalently bonded materials are generally less dense than ionically or metallically bonded ones.
For a trapezoidal shaped channel (n=0.014 and slope = 0.0002 with a 20-ft bottom width and side slopes of 1:1.5 (V:H), determine the normal depth using trial and error technique for a discharge of 1000 cfs.
