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?

the brightness of each bulb would decrease because the total resistance of the circuit would decrease.

the brightness of each bulb would increase because the total resistance of the circuit would increase.

the brightness of each bulb would remain the same even though the total resistance of the circuit would decrease.

the brightness of each bulb would remain the

The brightness will decrease with every light bulb added

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
