Railway track is made of steel segments separated by small gaps to allow for linear expansion. The segment of track is 10 m long when laid at temperature 17^ C . The maximum temperature that can be reached is 45^ C . Increase in length of the segment of railway track is ' x ' 10⁻⁵ ~m . The value of ' x ' is ( _ steel = . .1.2 10⁻⁵ / ^ C )
