Given alpha_(s) = 2 xx 10^(-5)//"^(@)C . (b) What will be the reading of scale at 40^(@)C if the actual length of objects is 10cm . (c ) What will be the actual length of object at 40^(@)C if is measured length is 10cm . (d) What is % error in measurement for part (b) and (c). (e) If the linear expansion coefficient of object is alpha_(0) = 4 xx 10^(-5) and neglecting the expansion of scale, then answers of (b) and (c) parts. (f) If alpha_(0) = 4 xx 10^(-5) and alpha_(s) =2xx 10^(-5) then find answers of (b) and (c) part.
