When the temperature drops to -14.2 °c, the ruler shrinks and no longer measures distances accurately. however, the ruler can be made to read correctly if a force of magnitude 1.95 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?
