a) Suppose a meter stick made of steel and one made of invar are the same length at 0 degrees celsius. what is their difference in length at 32.5 degrees Celsius? The coefficient of thermal expansion is 12 x 10^-6/degrees Celsius for steel and 0.9 x 10^-6/degrees Celsius for invar. (b) Repeat the calculation for two 16.0-m-long surveyor's tapes.
