The next few questions refer to the golden great bridge, built on planet tehar in a galaxy far, far away. the bridge-building technology on teacher is not very well developed: the bridge is just a long slab of pure gold with the opposite ends resting on the shores of the river.
in the spring, when the air temperature is 100°c , the length of the bridge is 160.0 m. answer the questions below knowing that the value of α for gold is 1.42 x 10^−5°c^−1. compared to its length in the spring, by what amount delta l winter does the length of the bridge decrease during the teharian winter when the temperature hovers around -150 °c ? and compared to its length in the spring, by what amount delta l summer does the length of the bridge increase during the teharian summer when the temperature hovers around 700°c?
