Question 12 (3 points)

Listen
Out in the Wild West during the time of Colonial Expansion, the native peoples would put their ears to the ground to listen for herds of bison or groups of horses in the area. Why would listening to the ground be more effective than cupping a hand around your ear while standing up on high ground?

Question 12 options:

The ground is denser than the air so the sound of a herd can be heard sooner through the ground than through the air.

The ground is less dense than the air so the sound of a herd can be heard sooner through the air than through the ground.

The ground is denser than the air so the sound of a herd can be heard sooner through the air than through the ground.

The ground is less dense than the air so the sound of a herd can be heard sooner through the ground than through the air.

Students in a science class were provided with this image and asked to identify which color of light would refract the most if white light was passed through a prism? Which student below identified the correct color of light with the proper justification?

Question 16 options:

Student 2: red, because it has the highest frequency

Student 1: red, because it has the highest velocity

Student 4: violet, because it has the highest frequency

Student 3: violet, because it has the highest velocity

Question 17 (3 points)

Listen
A plane is flying overhead. Will a person on the ground hear the airplane sooner on a cold day or a warm day and why?

Question 17 options:

The sound will travel faster on a cold day because the air particles have more potential energy and are closer together.

The sound will travel faster on a cold day because the air particles have more kinetic energy and are closer together.

The sound will travel faster on a warm day because the air particles have more potential energy and are moving faster.

The sound will travel faster on a warm day because the air particles have more kinetic energy and are moving faster.
