An O2− ion moves from a region where its electric potential energy is 12.0 × 10−18 J to one where its electrical potential energy is 7.6 × 10−18 J. Use e = 1.602 × 10−19 C. a. What is the change in potential energy?
b. What is the change in electrical potential (i. e. “voltage”)?

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

Convection currents are caused by differences in what two things?
