To determine the new resistivity and resistance of the wire after it has been stretched, we need to consider the concept of resistivity, which is the inherent property of the material from which the wire is made. Resistivity is usually denoted by the Greek letter ρ (rho).
The resistivity of a material is defined as the resistance offered by a wire of that material with a unit length and unit cross-sectional area. Mathematically, resistivity (ρ) is given by the equation:
ρ = R × (A / L)
where:
ρ = resistivity of the material,
R = resistance of the wire,
A = cross-sectional area of the wire, and
L = length of the wire.
In this case, we are given the initial resistance of the wire (R = 10 ohms). However, we don't have information about the original length, cross-sectional area, or resistivity. Therefore, it is not possible to determine the new resistivity and new resistance of the wire without more information.
To calculate the new resistivity and resistance after the wire has been stretched, you would need to know the stretching factor (the ratio of the new length to the original length) and the stretching factor for the cross-sectional area.
Once you have these additional details, you can use the formula mentioned earlier to calculate the new values of resistivity and resistance.
