A person is standing in the middle of a boxcar on a train moving 100 km per hour. If the motion of the boxcar remains constant, where in the boxcar will the person most likely land after he jumps straight up?
Horizontal forces act on two boxes, initially at rest, as shown. The magnitude and direction are of the horizontal forces are also shown. What happens to Box X and Box Y as a result of the forces?
Box X starts moving, speeding up, and Box Y remains at rest
Box X starts moving at constant speed, and Box Y remains at rest
Box X starts moving at constant speed, and Box Y starts moving, speeding up
Box X starts moving, speeding up, and Box Y starts moving at a constant speed

The pupil
What do the lens and cornea have in common?
They both send messages to the brain.
They can both change shape.
They both contain photoreceptive cells.
They both bend light into a focused beam.
How are rods different from cones?
Rods are sensitive to light, while cones can detect color.
Cones are sensitive to light, while rods can detect color.
Cones send images to the brain, while rods do not.
Rods send images to the brain, while cones do not.
What role does your brain play in the process of seeing?
It puts blurry images into focus.
It turns black-and-white images into color.
It flips upside-down images rightside-up.
It flips backwards images over so you see them the correct way.
What might happen if the lens of your eye became damaged?
Your eyes wouldn't be able to focus properly.
You wouldn't be able to see in color.
You wouldn't be able to see at night.
All the images you saw would be upside-down.
