A surveryor uses a steel measuring tape that is exactly 50.000 m long at a temperature of `20^(@)C`
What is its length on a hot summer day when the temperature is `35^(@)C`? `(alpha_("stell")=1.2xx10^(-5)K^(-1))`

A surveyor uses a steel measuring tape that is exactly 50.000 m long at a temperature of 20^(@)C What is its length on a hot summer day when the temperature is 35^(@)C ? (alpha_("steel")=1.2xx10^(-5)K^(-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) ?

A meter scale is made up of steel and measures correct length at 16^@C . What will be the percentage error if this scale is used (a) on a summer day when the temperature is 46^@C .

A steel rular exactly 20 cm long is graguated to give correct measurements at 20^@C . (a) Will it give readings that are too long or too short at lower temperatures? (b) What will be that actual length of the rular when it is used in the desert at a temperature of 40^@ C ? alpha_(steel = 1.2 xx 10^-5(.^@ C)^-1 .

A steel rular exactly 20 cm long is graduated to give correct measurements at 20^@C . (a) Will it give readings that are too long or too short at lower temperatures?
