What volume (in cm) of seawater would be needed to balance a 7.867 cm3 sample of gasoline on a two-pan laboratory balance.
Assume densities of 1.025 g/cm3 and 0.680 g/cm3 for seawater and gasoline,
respectively.

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?
