Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to calculate electric flux [title] Know the formula for electric flux. [substeps] The electric flux through a surface a is equal to the dot product of the electric field and area vectors e and a. the dot product of two vectors is equal to the product of their respective magnitudes multiplied by the cosine of the angle between them. [title] Determine the magnitude and direction of your electric field vector.

Ending1: [substeps] The energy field vector is abbreviated as an h (b). The sphere vector is abbreviated as a c (a). Ending2: [substeps] Note that most atomic energy used to generate electricity from planes passing in the area of the magnetic field is dispersed with energy from the surface of the magnetic field. [title] Interpret the concept as a predictive explanation or metaphor. Ending3: [substeps] This time measure the angle of the magnetic field. Know that the position of the magnetic field is more important than the distribution (the direction of the magnetic field). Ending4: [substeps] In most cases of this type, it is already given in the problem. [title] Determine the magnitude and direction of the surface area vector a.
