The average intensity of light emerging from a polarizing sheet is 0.689 w/m2, and that of the horizontally polarized light incident on the sheet is 0.930 w/m2. determine the angle that the transmission axis of the polarizing sheet makes with the horizontal.

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?
