Retain 3 significant figures in all answers, e.g. 0.0234 or 1.26104. 1. In Canada, the $2 coin consists of a smaller round metal coin made of aluminum bronze (92%Cu,6%Al,2%Ni) inside a larger metal ring made of 99% nickel. (a) Assume that the United States wanted to have its own $2 coin. The inner coin will be made of copper, and the outer ring will be made of aluminum. At 25C, the inner coin will have a diameter of 9.000mm, and the outer ring will have a diameter of 8.999 mm. To fit the two parts together, they are both heated up. Calculate the temperature at which the inner copper coin just fit inside the outer ring. Your solution should include a diagram illustrating your understanding of the
