Metre scales are madeup of alloy:

A metre scale made of steel reads accurately at 25^@C . Suppose in an experiment an accuracy of 0.06 mm in 1 m is required, the range of temperature in which the experiment can be performed with this metre scale is (coefficient of linear expansion of stoel is 11 xx 10^-6/(@C) )

What are alloys ? Name two alloys.

A metre scale is balanced on a knife edge at its centre. When a coin of mass 15 g is kept at the 12 cm mark, the scale is found to be balanced at 45 cm. What is the mass of the metre scale?

A metre scale is balanced on a knife edge at its centre. When a mass of 10 kg is kept at the 12 cm mark, the scale is balanced at 45 cm. What is the mass of the metre scale?

A metre scale is graduated at every millimetre. How many significant digits will be there in a length measurement with this scale?
