You send a wave down a spring. You then increase the tension (stretch it out) and send another wave down the spring. What happens to the speed of the wave when the tension increases?

A. the wave is slower
B. the wave is the same speed
C. the wave is faster

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?
