Athousand metal rods, each 3.0 cm in diameter and exactly 2.0 meters long at 5.0°c, 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 35.0°c, how could you identify the gold rod by examining the top of the stack? the coefficients of linear expansion are: 23×10-6 (c°)-1 and 14×10-6 (c°)-1.

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
