A copper rod of cm and an aluminium rod of unknown length have their increase in length independent of increase in temperature. The length of the aluminium rod is:
cm
cm
cm
cm
To solve this problem, we need to understand that the increase in length of both rods is independent of temperature.This implies that the thermal expansion of both rods is the same.The formula for linear expansion is:Where:•
