Need help ASAP1 What is the increase in length(cm) of 45m copper wire when its temperature changes from 15° C to 48° C. The linear expansion coefficient for copper is 1.7 × 10^-5 °C^-1.2 A container is marked at 50cm^3 and it is filled with mercury at that mark at a temperature of 20° C. Compute for the amount of mercury(cm^3) that will ne above the mark if its is heated to 38°C. αglass = 9.0 × 10^-6/ °C and βmercury = 182 × 10^-6 /°C.Thank you!
