Answer:

So after stretching new resistance will be 0.1823 ohm

Explanation:

We have given initially length of the wire l_1=150m

Radius of the wire r_1=0.32mm=0.32\times 10^{-3}m

Resistance of the wire initially R_1=90ohm

We know that resistance is equal to R=\frac{\rho l}{A} ,here \rho is resistivity, l is length and A is area

From the relation we can say that \frac{R_1}{R_2}=\frac{l_1}{l_2}\times \frac{A_2}{A_1}

Now length of wire become 6.75 m

Volume will be constant

So A_1l_1=A_2l_2

So \pi \times (0.32)^2\times150=\pi \times r_2^2\times 6.75

r_2=1.508mm

So \frac{90}{R_2}=\frac{150}{6.75}\times \frac{1.508^2}{0.32^2}

R_2=0.1823ohm
