Question

a length of 2m is measured using a metal tape at 10°C it is calibrated at a temperature
of 30°C the actual lenght is

Answer 1

Answer:

The metal tape is calibrated at 30oC to measure actual length.

At 10oC, the metal tap will contract so that the graduations of the scale will come closer. Hence, the steel tape will measure a length more than the actual length. If a length of 2m is measured using the metal tape at 10oC, its actual length will be less than 2m.
