A simple circuit contains a bulb, a battery, and a switch. If the voltage of the battery increases, what happens to the current through the bulb and the resistance of the bulb? a.)Resistance is unchanged, and current increases
b.)Resistance is unchanged, and current decreases
c.)Current is unchanged, and resistance increases
d.)Current is unchanged, and resistance decreases

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
