Let c be the closed, piecewise smooth curve formed by traveling in straight lines between the points (0, 0, 0), (2, 0, 14), (3, 2, 21), (1, 2, 7), and back to the origin, in that order. (thus the surface s lying interior to c is contained in the plane z = 7x.) use stokes' theorem to evaluate the following integral.

Need people build a dam to create a reservoir that supplies water a nearby city needs. describe two ways this action will likely affect the water cycle in the local environment. (5 points) worth 20 points
