Using the charts below, if you knew that a 1 mm diameter copper-nickel alloy wire can withstand a maximum load (before plastic deformation) of 78.54 N, and possesses an electrical resistance of 0.5 Ohms, then what is its length

L = 10.32 m

Explanation:

The resistance of a copper-nickel alloy wire is given by the following formula:

where,

R = Resistance = 0.5 Ω

ρ = resistivity of copper-nickel alloy = 3.8 x 10⁻⁸ Ωm

L = Length of wire = ?

A = cross-sectional area of wire = = 7.85 x 10⁻⁷ m²

Therefore,

L = 10.32 m

Technician B.

Explanation:

The starter motor is what turns the engine, until enough electricity is generated with momentum to keep the engine running and cycling. If there is a problem with the immobilizer, the engine may shake or come off the mount at higher RPMs, however, will not have any problems initially starting the engine. The starter is most important for starting the engine, therefore, Technician B is correct In this case.
