In deriving the axial electric field for the ring-shaped charge distribution and the electric field from a long line of charge, the component perpendicular to the resulting field is zero because of what physical property?a) integration b) superposition c) only net charge is important d) symmetry e) positive and negative charges

B) Superposition

Explanation:

This is because the horizontal components of the electric field at a point on the axis of the ring cancel out, due to the fact that the horizontal components of the electric field due to the differential charges at opposite points of the ring point in opposite directions.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
