An indirect lighting system is used to light a square room with a floor area of 400 ft2 . The luminaires in the room uniformly light the ceiling, which is 20 ft high. The walls and floor of the room are very dark and can be assumed to have a reflectance of zero. The ceiling has a reflectance of 0.8. How many lumens must be produced by the luminaires to provide 10 fc on the floor of the room?

Four equal charges are located at the corners of a square of side d. If the magnitude of each charge is doubled, then what happens to the resultant force on each charge? It is doubled. It is quadrupled. It increases by a factor of 8. It remains the same. None Of the other choices is correct. A particle travelling along the +x-axis enters an electric field directed vertically upward along the +y-axis. If the particle experiences a force downward because...
