Refer to a long, straight wire carrying constant current I. What can be concluded about the magnitude of the magnetic field at d
sergij07 [2.7K]

Answer:

<em>"the magnitude of the magnetic field at a point of distance a around a wire, carrying a constant current I, is inversely proportional to the distance a of the wire from that point"</em>

Explanation:

The magnitude of the magnetic field from a long straight wire (A approximately a finite length of wire at least for close points around the wire.) decreases with distance from the wire. It does not follow the inverse square rule as is the electric field from a point charge. We can then say that<em> "the magnitude of the magnetic field at a point of distance a around a wire, carrying a constant current I, is inversely proportional to the distance a of the wire from that point"</em>

From the Biot-Savart rule,

B = μI/2πR

where B is the magnitude of the magnetic field

I is the current through the wire

μ is the permeability of free space or vacuum

R is the distance between the point and the wire, in this case is = a

1. If a model train car with a momentum of 12 kg•m/s collides with a 2 kg model train car that is not moving, what is the total
wariber [46]

Answer:

P_{f} = 12 \ kg.m/s

Explanation:

Given data:

Momentum of moving model train, P_{1} = 12 \ kg.m/s

Mass of the stationary model train, m = 2 \ kg

Initial speed of the stationary model train, v = 0

Assume there is no external force is acting on the given train system.

In this case, the total linear momentum of the trains would be conserved.

Let the final linear momentum of the trains be P_{f}.

Thus,

P_{i} = P_{f}

P_{1} + P_{2} = P_{f}

P_{1} + mv = P_{f}

12 + 2 \times 0 = P_{f}

\Rightarrow \ P_{f} = 12 \ kg.m/s.
