Three different alloys used in home are brass, bronze and copper. Brass and bronze are used for utensils and copper is used in the electrical circuits.
<h3>What are alloys?</h3>
Alloys are the homogeneous mixture of metal mixed with metal or non metal. These alloys can't be separated by physical methods.
The alloy brass and bronze are used for utensils and copper is used in the electrical circuits.
The properties of the alloys make it suitable for that application is the electrical conductivity and their melting point.
Brass and Bronze are bad conductors of electricity. On the other side, copper is used in electrical circuits.

Divide the long wire in small segments. The field due to one segment can be found from Biot- Savart law.
dB=(uo/4pi) Idlxr/r^3. In this expression if we take vector r perpendicular to current element , the cross product in the expression shows that the direction of B is perpendicular to vector r and from symmetry it can be said that field line is circular around the wire segment. This is true for all segment ,because in infinitely long wire all segments are equivalent . Thus, magnetic field lines are concentric around a long straight wire.
Hope it helps
Answer:
Same
Explanation:
While moving through a magnetic field in a direction perpendicular to a B-field, a continuous force experienced by a charged particle. If this magnetic field remains uniform, the force exerted also remains same and hence the velocity with which the particle is moving remains same. However, the particle is forced to move on a curved path until it forms a complete circle.
Hence, the kinetic energy remains the same because the speed is same
