A steel tape gives corrent measurement at 20^(@)C. A piece of wood is being measured with the steel tape at 0^(@)C. The reading is 25 cm on the tape. The real length of the given pices of wood must be

A steel tape gives corrent measurement at 20^(@)C. A piece of wood is being measured with the steel tape at 0 C.' The reading is 25 cm on the tape. The real length of the given pices of wood must be

A metal tape gives correct measurement at 15^(@)C . It is used to measure a distance of 100m at 45^(@)C . The error in the measurement, it alpha=12xx10^(-6)//1^(@)C is

A steel scale gives correct reading at 10^(@)C . If the length of a rod is measured with the help of that scale at 30^(@)C then the measured length will be

A metal scale measures correct reading at 25^(@)C. A rod is measured to be 80 cm by the scale at 15^(@)C . What is the actual length of the rod? (alpha=15 times 10^(-6@)C^(-1))
