The potential energy function for either one of the two atoms in a diatomic molecule is often approximated by U(x)=a/x^{12}-b/x^6U(x)=a/x 12 −b/x 6 where xx is the distance between the atoms. Find the distance of separation where the potential energy has a local minimum.

Two friends at different locations want to communicate with each other by sending low energy signals. which of the following methods can they use to communicate? a) produce x-rays using colliding electrons and send them to radios, which capture sound b) send messages using infrared radiation, which travel in the form of waves c) send radio waves through intervening media like radio and television d) produce sound waves using microwaves from heated objects

Select all that apply. a beta particle: is electromagnetic energy is an electron has zero charge is emitted from the nucleus has a +2 charge has a -1 charge
