A steel tape is callibrated at `20^@ C`. On a cold day when the temperature is `-15^@ C`, what will be the percentage error in the tape ?

A steel tape is callibrated at 20^(@)C . When the temperature of the day is -10^(@)C , the percentage error in the measurement with the tape is (alpha=12" "10^(-6)//""^(@)C)

A steel taps is calibrated at 20^(0)C . When the temperature of the day is -10^(0)C , the percentage error in the measurement with the tap is (alpha = 12 xx 10^(-6 //0)C)

A steel tape placed around the earth at the equator when the temperature is 10^(@)C . What will be the clearance between the tape and the ground (assumed to be uniform) if the temperature of the tape rises to 40^(@)C ? Neglect expansion of the earth. Radius of earth at equator is 6400 km & alpha_(steel)= 1.2 xx 10^(-5)K^(-1)

A steel tape is correctly calibrated at 20^(@)C and is used to measure the length of a table at 30^(@)C . Find the percentage error in the measurement of length. [alpha_(steel) = 11 xx 10^(-5)//.^(@)C]

A precise steel tape measure has been calibrated at 20^(@)C . At 40^(@)C a. will it read high or low, and b. what will be the percentage error?
