Using 0.500 g of nichrome, you are asked to fabricate a wire with uniform cross-section. The resistance of the wire is 0.673 Ω. The nichrome has a resistivity of 1.00 10^-6 Ω · m and a density of 8.31 10^3 kg/m^3.

a. What length of wire do you end up with?
b. What is the radius of the wire?

Explanation:

Given that,

Mass of Nichrome, m = 0.5 g

The resistance of the wire, R = 0.673 ohms

Resistivity of the nichrome wire,

Density,

(A) The length of the wire is given by using the definition of resistance as :

Volume,

Area,

....(1)

(b)  Equation (1) becomes :

Hence, this is the required solution.                                                                  

c

explanation:

i believe the answer is c and this is only worth 10 points you might wanna change it
