Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?
Moving the cart on Track 1 one space to the right (→).
Moving the cart on Track 2 one space to the left (←).
Moving the cart on Track 2 one space to the right (→).
All these movements will result in the same change in potential energy because they each move a cart the same distance.

Why can't sound travel through outer space?
There is almost no matter in outer space, so the vibrations have no way to travel through the atmosphere. There is nothing to carry the sound waves through space.
Sound actually travels very quickly through outer space because there is no matter to slow down the sound waves.
There are too many planets and stars in outer space that absorb all of the sound waves, so they cannot travel to the human ear.
Because outer space is a "vacuum," the vibrations are irregular and travel in too many directions for us to detect the sound.
Sound waves can travel through all three states of matter. Which of the following best explains why sound travels most quickly through a solid?
Solids always produce an echo, which makes the sound seem louder to the human ear.
Only solids allow the vibrations to travel from one atom (particle) to another.
In solids, the atoms (particles) are closest together, which allows the vibrations to travel rapidly from one to another through the object.
Sound does not travel quickly through a solid. It travels most rapidly through a gas.
What does the pencil in this picture show about light?
Light is refracted when it hits a curved object.
Light is reflected when it hits a curved object.
Light is refracted when it passes from air into water.
Light is reflected when it passes from air into water.
A leaf is green. What does this tell you about the light that is being absorbed?
The light is a UV ray.
The light is not a part of the light spectrum.
All colors are reflected except green.
All colors are absorbed except green
