What is a disadvantage of the series if more light bulbs were added A.
If more light bulbs are added, resistance decreases, the current and the brightness of the light bulbs decrease.

B.
If more light bulbs are added, resistance decreases, the current and the brightness of the light bulbs increase.

C.
If more light bulbs are added, resistance increases which causes the current, and the brightness of the light bulbs to decrease.

D.
If more light bulbs are added, resistance increases which causes the current and the brightness of the light bulbs to increase.

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
