Which statement best explains the relationship between current, voltage, and resistance? a
.If we increase the amount of voltage applied, and do not change the resistance, this will result in a decrease in current.

b. If we decrease the current applied, and do not change the resistance, we increase the voltage.
d. If we increase the amount of voltage applied, and do not change the resistance, we will also increase the current.

c. If we decrease the amount of current, this will not affect the amount of voltage, only the amount of resistance.

Ascientific blank must be testable and capable of being proven false?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
