En i interior de un campo magnetico
uniforme se coloca un alambre conductor
recto que lleva una corriente de 10 a.
la magnitud del campo magnetico es de 0.5 t
el angulo entre el conductor y el campo magnetiro
es de 45°
calcular la magnitud de la fuerza por unidad de longitud
que siente el alambre

The best answer is (a) which is universal law is in effect at all times. it is constantly at play in everything we do and governs our lives. it is also important to note that universal law applies to not only everything on earth, but everything in the universe as well, which is another reason why it is in effect at all times.

Ibelieve that the correct answer is: c. along plate boundaries

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
