Answer:

Explanation:

For resistance the formula is as follows

R = ρ L/S

where L is length of the wire , ρ is a constant for a specific material called specific resistance and S is cross sectional area .

For 0.6 m wire , putting the values

.13 = ρ x 0.6 / S

For unknown wire

R = ρ x 187 / S

Dividing the two equations

R / .13 = 187 / .6

R = (.13 x 187) / .6

= 40.5 ohms .
