Gce Model Questions Vol1 2021 Physics Question 27
Practice objective / multiple choice question 27 from the 2021 Gce Model Questions Vol1 Physics examination.
A composite rod consists of two metal strips joined end‑to‑end. Strip A is \(0.40\ \text{m}\) long with coefficient of linear expansion \(\alpha_{A}=12\times10^{-6}\ \text{°C}^{-1}\). Strip B is \(0.60\ \text{m}\) long. After heating, the total length becomes \(1.050\ \text{m}\) and the length of strip A becomes \(0.405\ \text{m}\). Determine the coefficient of linear expansion \(\alpha_{B}\) of strip B (in \(\text{°C}^{-1}\)).
