Objects a, b, and c are at different temperatures, a lowest and c highest. the three objects are put in thermal contact with each other simultaneously. without doing a calculation, is it possible to determine whether object b will gain or lose thermal energy?

Identify the forces that contribute to the centripetal force on the object in each of the following examples: a. a bicyclist moving around a flat, circular track b. a bicycle moving around a flat, circular track c. a racecar turning a corner on a steeply banked curve

If an atom contains 11 protons in its nucleus, predict the element with the atomic number and electronic configuration. will the number of electrons remain the same during the chemical reaction in such an atom? explain.
