Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field acting perpendicular to its axis of rotation. Coil 1 has a radius of 6.0 cm and rotates in a 0.25-T field. Coil 2 rotates in a 0.53-T field. Each coil experiences the same maximum torque. What is the radius (in cm) of coil 2

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.

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.
