A physics professor in a lab releases a 1.44-m long simple pendulum (with a 590 g mass attached) at an angle of 15° to the vertical. Assuming that the pendulum undergoes simple harmonic motion: (a) what is the frequency of the pendulum’s oscillations? (b) What is the pendulum bob’s speed at the lowest point of its motion?

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?
