A thousand metal rods, each 3.0 cm in diameter and exactly 2.0 meters long at T = 5.0C, are bundled together. The bundled stack is tipped up so that that the bottom of the stack rests on a hard floor, and the ends of the rods at the top are exactly the same height. They are all painted gold, but only one of them actually is gold. The rest are aluminum. If the room is warmed to 35.0C, how could you identify the gold rod by examining the top of the stack? The coefficients of linear expansion are: aa1 =23x 10-6 (C) and aau =14x10-6 (c)!. O There would be no way to tell. O The end of the gold rod will be higher than the others. O The end of the gold rod will be lower than the others. What the difference in lengths between gold rod and an aluminum rod at 35.00C if their original lengths were 2.000 m at 5.000C? 0.54 mm There would be no difference. O 0.84 mm O 1.38 mm
