If we talk about rolling, we have to use as a definition a combination of rotation and translation of object with respect to a surface. Now, when the object is rolling without sliding is referred to as pure rolling.

I hope it helps you!

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation R=pL/(pi)d^2 where p represents the resi

SashulF [63]

Answer:

The resistance approaches infinity

Step-by-step explanation:

We are given

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation

$R=\frac{\rho L}{\pi (d)^2}$

where

p represents the resistivity of the wire’s material

L represents the length of the wire

d represents the diameter of the wire

now,

d approaches to 0

so, we can plug d=0 and find R

$R=\frac{\rho L}{\pi (0)^2}$

$R=\frac{\rho L}{0}$

$R=\infty$

So,

The resistance approaches infinity
