Question

On a cold day, a metal measuring tape graduated in millimetres is used to measure the distance
between two fence posts. The measuring tape reads $$3.000m$$.
On a much hotter day, the metal measuring tape is used to measure the length of the same
distance again. The metal measuring tape has a higher temperature than the ground. The
temperature of the ground remains constant.
Which statement is correct?


A
The measuring tape reads less than 3.000 m because the graduations are closer together
loader
B
The measuring tape reads less than 3.000 m because the graduations are further apart
loader
C
The measuring tape reads more than 3.000 m because the graduations are closer together
loader
D
The measuring tape reads more than 3.000 m because the graduations are further apart
loader

Solution

The correct option is B The measuring tape reads less than $$3.000\ m$$ because the graduations are further apart
$$(B)$$: 
Metal expands on increasing the temperature
During hotter day length of meter tape will be more as compared to cold day  
so separation between graduation will be more and it will read the same length as less than as compared to measured on cold day
