A rotating wheel requires 2. 98-s to rotate through 37. 0 revolutions. Its angular speed at the end of the 2. 98-s interval is 97. 2 rad/s. What is the constant angular acceleration of the wheel?.

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?
