what is the increase in length of a copper rod of length 10 m from 10 degrees Celsius to 80 degrees Celsius if the linear expansivity of the copper rod is 17 x 10-6 per kelvin
If the linear expansivity of a copper rod is 0.000017/k, calculate the expansivity of 10m of copper rod when heated from 10 degree celcius to 80 degree celcius.
