at a particular instant a hot air ballon is 100 m in the air and descending at a constant speed of 2,0 m/s. at this exact instant a girl throws a ball horizontally relative herself with an initial speed of 20,0 m/s when she lands where will she find the ball ?

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?
