What should bethe velocity of the bullet so that it is just able There is an object oplaced between the mirrors, at 10 cm from mirror M2. Unit of heat: Because heat is a form of energy, its units are those of energy, namely, the joule (J) in the SI system. Heat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3. Answer: unit joule As a form of energy, heat has the unit joule (J) in the International System of Units (SI). A The M.K.S. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.
