Need this question answered in python. Science P5.35 Electric wire, like that in the photo, is a cylindrical conductor covered by an insulat- ing material. The resistance of a piece of wire is given by the formula where p is the resistivity of the conductor, and L, A, and d are the length, cross- sectional area, and diameter of the wire. The resistivity of copper is 1.678 × 10-8 Ω m. The wire diameter, d, is commonly specified by the...
The resistance R of a wire of length l and uniform area of cross-section A is given by R = rhol/A, where rho is the resistivity of the wire. You melt the wire and recast it to have a new length l' = 10l (keeping the volume V = Al of the wire constant). What is the new resistance of the wire, if the original resistance of the wire was 100.0 Ohm.

Please answer all parts! Thanks. I. It is desired to construct a solenoid that will have a resistance of 6.00 Ω at 20°C and produce a magnetic field of 4.00 × 102 T at its center when it cames a current of 3.40 A. The solenoid is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenoid is to be 1.00 cm, determine the following. (The resistivity of copper at 20°C is...
