A light ray strikes a hexagonal ice crystal ( nice​=1.30) floating in the air (nair ​=1.00) as shown in the figure. All the rays shown are in the plane of the page. Which outgoing ray is the correct one? c A B E none of the other answers is correct
Aluminum has a specific heat more than twice that of copper. Identical masses of aluminum and copper, both at 0∘C, are dropped together into a can of hot water. When the system has come to an equilibrium, the aluminum mass is at a lower temperature than the copper mass the difference in temperature between the aluminum mass and the copper mass depends on the initial temperature of the water in the can the aluminum mass is at a higher temperature than the copper mass the aluminum mass is at the same temperature as the copper mass
