What are the problems caused by thermal expansion and how they can be solved​

uranium fissions/breaks up giving out energy and neutrons

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

iron would move it is magnetic there is a mag field around the current in the wire

be subject to a force andchange its motion
