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 metallic tape gives correct value at 25^(@)C .A piece of wood is being measured by this metallic tape at 10^(@)C . The reading is 30 cm on the tape, the real length of wooden piece must be

A metallic tape gives correct value at 25^(@)C .A piece of wood is being measured by this metallic tape at 10^(@)C . The reading is 30 cm on the tape, the real length of wooden piece must be

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 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 is correct at 0^(@)C . The length of a brass tube measured by it at 40^(@)C is 4.5m . The correct length of the tube at 0^(@)C is (Coefficients of linear expansion of steel and brass are 11 xx 10^(-6//@)C and 19 xx 10^(-6//@)C respectively).

A steel scale is correct at 0^(@)C . The length of a brass tube measured by it at 40^(@)C is 4.5 m. The correct length of the tube at 0^(@)C is (Coefficients of linear expansion of steel and brass are 11xx10^(-6)//""^(@)Cand19xx10^(-6)//""^(@)C respectively.)

The length and breadth of a steel tape are 10m and 2.4cm, respectively. The ratio of the length to the breadth is
