Acircuit contains two light bulbs connected in parallel. what would happen to the brightness of each light bulb if two more light bulbs were added in parallel to the first ones?
a. the brightness of each bulb would decrease because the total resistance of the circuit would decrease.
b. the brightness of each bulb would increase because the total resistance of the circuit would increase.
c. the brightness of each bulb would remain the same even though the total resistance of the circuit would decrease.
d. the brightness of each bulb would remain the same even though the total resistance of the circuit would increase.

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
