Two tensiometers were installed in a soil profile. One is placed at 30 cm and the other at 50 cm below the surface. The matric pressure heads are -500 cm for the top and -450 cm for the bottom tensiometer. Is there any water flow in the profile? If yes, in which direction does the water move?

The two required components for a generator

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
