Neco Model Questions Vol1 2022 Physics Question 12
Practice objective / multiple choice question 12 from the 2022 Neco Model Questions Vol1 Physics examination.
A metal rod of length 1.20\,m at 20\,°C expands linearly with a coefficient of linear expansion \( \alpha_{r}=12\times10^{-6}\,^{\circ}\!\text{C}^{-1}\). The scale attached to the rod also expands, having a coefficient \( \alpha_{s}=5\times10^{-6}\,^{\circ}\!\text{C}^{-1}\). If the length indicated on the scale increases by 0.018\,mm, calculate the temperature change of the rod.
