3. experimental studies for a simple, nonpolar gas a indicate that then two molecules of the species a are 2 molecular diameters apart, the potential energy (aa) is –8×10–16 erg. consider instead two simple nonpolar molecules of species b. when these two molecules are 2 molecular diameters apart, what is their potential energy (bb)?

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
