Two identical blocks are connected to opposite ends of a compressed spring. the blocks initially slide together on a frictionless surface with a velocity v to the right. at some instant, the left block is moving at v/2 to the left and the other block is moving to the right. what is the speed of the center of the mass of they system at that instant?

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

The mini-refrigerator fire was most likely caused by what type of wiring?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
