Pls. answer this fast​

Answer 1

$given - \\ \\ l_{1} = 35.2 \binom + - 0.1 \: cm \\ l_{2} = 47.4 \binom + - 0.2 cm\\ \\ sol - \\ \\ l = l_{2} - \: l_{1} \\ = > 47.4 - 35.2 = 12.2cm$

:• error is additive in nature

$∆l= ∆log_{1}+ ∆log_{2} \\ \\ => 0.2+0.1 = 0.3cm$

therefore, the elongation in the wire with error limits is ;

$12.2 \binom{ + }{ - } 0.3cm$
