BRAINLIEST + THANKS GIVENWhat happens to the brightness of lightbulbs if you add them to each circuit?Adding bulbs to a series will make them dimmer because current is reduced, adding bulbs to a parallel will make them brighter because the current through each individual bulb goes up.Adding bulbs to a series will make them brighter because each bulb will take more current, adding bulbs to a parallel will not affect the brightness because the current through each individual bulb remains the same.Adding bulbs to a series will make them dimmer because current is reduced, adding bulbs to a parallel will not affect the brightness because the current through each individual bulb remains the same.Adding bulbs to a series will make them brighter because current is increased, adding bulbs to a parallel will make them dimmer because the current has to be split up between them.

Two cars, each having a mass of 1,000 kg are being tested at the Department of Highway Safety facility. Car A is moving at 30 m/s to the north. Car B is moving at 15 m/s to the south. When they collide, which of the following is true? a- Car A applies a greater force on car B than car B applies on car A. b- Car A applies a force on car B equal to the force car B applies on car A. c- Car B applies a greater force on car A than car A applies on car B. d-Car A and car B do not have the same velocity; you cannot compare the forces.
