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.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
