Xavier throws a tennis ball to his friend olaf at a 20° angle relative to the ground with an initial velocity of 18 m/s. the tennis ball travels 30 m until olaf catches itthe time the tennis ball was in the air, rounded to the nearest hundredth, is s.

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?
