How are light waves and primary earthquake waves (P-waves) different?

• Light waves are longitudinal and P-waves are transverse.

• Light waves are transverse and P-waves are longitudinal.

• Light waves transport matter away from the light source, but P-waves do not.

• Light waves do not transport matter away from the earthquake source, but P-waves do.

This diagram shows the path of a light ray as it reflects from the fish, travels through water, enters the air, and then enters the man’s eye. What does the image show?

• The light ray refracts as it moves from water to air.

• The light ray diffracts as it moves from water to air.

• The light ray reflects as it moves from water to air

• The light ray is absorbed as it moves from water to air.

A person becomes deaf because the part of the ear that sends signals to the brain is damaged. Which part of the ear is most likely affected?

• cochlea

• ossicles

• eardrum

• ear canal

Which statement best explains how music is converted into electrical signals in a person’s brain?

• Music makes the eardrum vibrate. The eardrum’s vibrations are then transmitted to the outer ear, which converts the vibrations into electrical signals that are sent to the brain.

• Music makes the outer ear vibrate. The outer ear’s vibrations are then transmitted to the eardrum, which converts the vibrations into electrical signals that are sent to the brain.

• Music makes the eardrum vibrate. The eardrum’s vibrations are then transmitted to the inner ear, which converts the vibrations into electrical signals that are sent to the brain.

• Music makes the inner ear vibrate. The inner ear’s vibrations are then transmitted to the eardrum, which converts the vibrations into electrical signals that are sent to the brain.

What is true of iron atoms and carbon atoms?

• They are the same because they are from the same elements.

• They are different because they are from different elements.

• They are the same because they have the same properties.

• They are different because one is solid and one is liquid.

A scientist compares two pieces of metal. The first piece is pure copper. It is shiny, brown, and flexible. The second piece is pure iron. It is dull, gray, and inflexible. What can be concluded from this information?

• One piece of metal is larger than the other.

• They are composed of the same type of atoms.

• They are composed of different types of atoms.

• One piece of metal weighs more than the other.
