1) An object is hung using a metal spring. If now a current is passed through the spring, what will happen to this system?
son4ous [18]

Answer:

D) The spring will contract, raising the weight.

Explanation:

According to the statement there is current that will enter the current through the metal ions that it has in its stratum. The passage of the current will generate within the spring a magnetic field that travels in a loop. That is, while the upper part of the spring which is also that of the spring acts as a north pole, the lower part of the spring and the magnetic field will act as the south pole. The position of the poles will generate an opposition effect that will generate an attraction to each other which will generate a contraction in the spring and an increase in weight on it.

A wire of a given material has an electric field of 0.100 mV/m when a potential is applied. The wire has 8.49 x 1028 conduction
Bond [772]

The uniform current density in the wire is 5.43 x 10²⁷ A/m².

<h3>Current density in the wire</h3>

The uniform current density in the wire is calculated as follows;

J = total current / total area

The given parameters:

  • Conduction of the wire = 8.49 x 10²⁸ e/m²
  • time, t = 2.5 x 10⁻¹⁴ s

J = \frac{I}{A} = \frac{Q}{At} \\\\J = \frac{8.49 \times 10^{28}e/m^3 \ \times \ 1.6 \times 10^{-19} \ C/e}{2.5 \times 10^{-14} \ s \ \times ( 0.1 \times 10^{-3} \ V/m)} \\\\J = 5.43 \times 10^{27} \ A/m^2
