Q. Two bars of identical mass are at 28 °C. One is made from glass and the other from another substance. The specific heat capacity of glass is 840 J/(kg • C°). While identical amounts of heat are supplied to each, the glass bar reaches a temperature of 93 °C, while the other bar reaches 255 °C. What is the specific heat capacity of the other substance?
Q. a) At what angle does the target particle move after the collision? b) What are the final speeds of the two particles? c) What fraction of the initial kinetic energy is transferred to the target particle? An atomic nucleus of mass m travelling with speed v collides elastically with a target particle of mass 2.000m (at first at rest) and is scattered at 90.
