Aseries circuit contains four light bulbs. the switch is opened and one of the bulbs is removed, but not replaced. then the switch is closed again. what would you expect to see?
a) all three remaining light bulbs will be on.
b) none of the remaining light bulbs will be on.
c) only the bulb closest to the switch will be on.
d) all three remaining light bulbs will be brighter than before.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
