We have a 10 m resistance wire of the isachrom 60 type. The resistance of this wire is 5.65 Ω / m at 20 ° C. The wire has a diameter of 0.50 mm. a. Calculate the resistivity of isachrom 60 at 20 ° C.

Explanation:

Given that,

The length of the resistance wire, l = 10 m\

The  resistance of this wire is 5.65 Ω/m

The diameter of the wire, d = 0.5 mm

Radius, r = 0.25 mm = 0.00025 m

We need to find the resistivity of isachrom 60 at 20°C. The formula for the resistance of a wire is given by :

The resistivity of the wire is .

positive reinforcement? ?

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
