At room temperature (`25^@C`) the length of a steel rod is measured using a brass centimetre scale. The measured length is 20 cm. If the scale is calibrated to read accurately at temperature `0^@C`, find the actual length of steel rod at room temperature.

The length of a rod is measured as 31.52 cm. Granduations on the scale are upto

The length of a rod is measured as 31.52 cm. Granduations on the scale are upto

The length of a rod is measured as 31.52 cm . Graduations on the scale are up to

A steel tape 1 metre long is correctly calibrated for temperature of 27.0^@C . The length of a steel rod measured by this tape is found to be 63.0 cm on a h ot day when the temperature is 45^@C . What is the actual length of the steel rod on that day? What is the length of the same steel rod on a day when the temperature is 27.0^@C ? Coefficient of linear expansion of steel = 1.20 xx 10^-5 C^-1 .

A steel tape 1 m long is correctly cailbrated for temperature of 27.0^(@)C . The length of a steel rod measured by this tape is found to be 63.0 cm on a hot day when the termperature is 45.0^(@)C . What is the actual length of the steel rod on that day? What is the length of the same steel rood on a day when the temper ature is 27.0^(@)C ? alpha of steel is 1.20xx10^(-5)""^(@)C^(-1) ?
