(Answered) A ruler is accurate when the temperature is 248 degc when

Academics

A ruler is accurate when the temperature is 24.8 °C. When the temperature drops to -12.1 °C, the ruler shrinks and no longer measures distances accurately. However, the ruler can be made to read correctly if a force of magnitude 1.77 x 10³ N is applied to each end so as to stretch it back to its original length. The ruler has a cross-sectional area of 1.38 x 10^-5 m², and it is made from a material whose coefficient of linear expansion is 2.5 x 10^-5 (C°)^-1. What is Young's modulus for the material from which the ruler is made?
