Question

A glass rod is measured with a zinc scale, both being at $20 to the power of ring operator end exponent c$ appear to be a metre long. If the scale is correct at $0 to the power of 0 end exponent c$ , what is the true length of the glass rod at $0 to the power of 0 C ?$ a of zinc $equals 0.000029 divided by blank to the power of 0 C comma$ a of glass $equals 0.0000085 divided by blank to the power of 0 end exponent C$

80.6 cm
90.4 cm
100.04 cm
121.6 cm

The correct answer is: 100.04 cm
