A color television tube also generates some x rays when its electron beam strike the screen. What is the shortest wavelength of these x rays if a 25. 5 kv.

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?

Which of these activities increases the amount of carbon in the atmosphere?

How does the strength of the electrostatic force between an electron and a proton compare to the strength of the gravitational force between them?
