What is air pressure Retardation 3 4. An iron scale is unmodified at 0 ° C. Zinc rods Is when both the rod and the scale are at 0 ° C. What is the length of the rod measured by the scale Given: Ciron = 1.2x 10-5 ° C-1 and ai = 2.6 x 10-5 ° C-1. Cut length 10 Will be set when two

A brass scale is correct at 20^@C . The length of a rod measured by it at 35^@C is 60 cm . What is the correct length of rod at that temperature ? ( alpha of brass = 18.9 xx 10^(-6) per^@C) .

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))

A steel rod of length 20 3/26 is cut down from a rod of length 56 1/5 what when is the remaining length of the rod?

Length of a metal rod at temperature 27^@ C is 4.256m. Find the temperature at which the length of the same rod increases to 4.268m. ( alpha for iron = 1.2 xx 10^(-5) K^(-1) )

An iron scale is correct at 0^(@)C an at this temperature, a zinc rod measures 1m on this scale. What will be the length of the zinc rod as measured by the iron scale when both the are at 100^(@)C ? (Linear expansivity of zinc =126xx10^(-6)K^(-1) and linear expansivity of iron =12x10^(-6)K^(-1) )

A zinc rod is measured by means of a brass scale (Which is correct at 0°C ) and is found to be 1.0001 metre long at 10°C .What is actual length of the rod at 0°C ?( alpha forZn= 29*10^-6/°C , alpha for brass= 19*10^-6/°C ).
