Which statement is true?
a) in a series circuit, the resistors do not share the current.
b) in a series circuit, as light bulbs are added, the bulbs dim.
c) in a series circuit, if one bulb goes out the other bulbs will stay lit.
d) in a parallel circuit, if one bulb goes out, all of the bulbs will go out.

B.) In a series circuit, as light bulbs are added, the bulbs dim.

Explanation:

In a series circuit, as light bulbs are added, the bulbs dim. In a series circuit the bulbs are wired in a line. As more bulbs are added in series, the current flowing through all the bulbs decreases. The bulbs then dim as more are added

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
