Answer to Question #159097 in Physics for Olamiposi

Question

A copper rod whose length is 10.0 is heated to 50°c. Find its New length take linear expansivity of copper as 0.000017

Answer 1

The equation of linear heat expansion says

$$l=l_0(1+\alpha \Delta t)\\ l=\rm 10.0\times (1+0.000017\times 50)= 10.0085\: m$$
