Which of the following statements are true? check all that apply. check all that apply. in order to maintain a steady flow of current in a conductor, a steady force must be maintained on the mobile charges. in a circuit, current is delivered by the positive terminal of a battery, and it is used up by the time it returns to the negative terminal of the battery. current is the total amount of charge that passes through a conductor's full cross section at any point per unit of time. by convention, the direction of a current is taken to be the direction of flow for negative charges. when an electric field is applied to a conductor, the free electrons move only in the direction opposite the applied electric field. submitrequest answer provide feedback next g

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
