(21). Determine (construct) a triple integral that will compute J J Jp # dV where D is the solid tetrahedron with vertices (0,0.0) , (1,0,0), (0,2,0) and (0.0,4). Do not evaluate the (triple) integral. 22. Evaluate JJs F - dS where Fucactus) , zr - 3y, 2+ 2s' > and where 5 is (the closed) surface of the the solid region bounded above by the hemisphere s' + p' + :3 =9 (: 2 0) and bounded below by the disk; "+ $9 (z = 0) and where the normal n points "outward". 81# 17 23. Compute JJ, F . dS where Fm and where S is the closed surface S of the box/cube enclosed by the planes s = 0, = = 2, y = 0, y - 2, = = 0, and = = 2, with normal n pointing "outward". I think It's 16. Hint: This problem can be made reasonably sample if you make use of the divergence theorem 24. Evaluate Jf, F . as where Fecal-2 , y) -2, 2-2-y > and where S is the closed surface bounded above by the parabolold = = 4-23-y' and bounded below by the disc alty' $ 4:2=0 and where the normal n points "outward". Hint: This problem can be made reasonably simple if you make use of the divergence theorem
