Compute each part of given question:
Question: The tune of a string instrument will change if it is heated or cooled because the different materials expand or shrink in different ways, resulting in changes in tensions. A violin string made of steel with a coefficient of linear expansion of 4.4 x 10-5 degree Celsius. It is mounted on a wood frame with a coefficient of linear expansion of 0.6x10-5 degree Celsius. If the temperature decreases by 18 degree Celsius, then
Part A: Which will shrink more?
Part B: Calculate by how much each will shrink if both are initially 33 cm long?
I want help to calculate by how much each will shrink if both are initially 33 cm long.
