A sound wave that occurs at a quick rate and has a high frequency would produce...

• A. A loud sound.

• B. A low-pitched sound.

• C. A high-pitched sound.

• D. A soft sound.

Carrie is learning about how a guitar string affects the pitch of the sound it makes. How could she increase the pitch of a sound produced by a string on a guitar?

• Pluck the string with more force to make it vibrate faster.

• Loosen the string on the guitar so the string vibrates faster.

• Tighten the string on the guitar so the string vibrates faster.

• Tighten the string on the guitar so the string vibrates slower.

What is the term used to describe the amount of space an object occupies?

• Weight

• Density

• Volume

• Area

Compare the graduated cylinder to the beaker. Which one would you use to get a more accurate volume measurement?

• Beaker

• Graduated cylinder

• Both are equally accurate

• Neither, use a measuring spoon

How can you measure the volume of an object using water displacement?

• By weighing the object before and after submerging it in water

• By calculating the difference in water level before and after the object is submerged

• By measuring the amount of water that overflows when the object is submerged

• By observing the change in color of the water when the object is submerged

Based on the diagram, what is the volume of the object submerged in water?

• 10 cm³

• 50 cm³

• 60 cm³

• 110 cm³

Does the shape of an object affect its volume?

• Yes, changing the shape of an object will always change its volume.

• No, changing the shape of an object does not change its volume.

• Yes, but only if the object is made of clay.

• No, changing the shape can only change the object's color.

Marsha’s teacher wanted her to find the volume of a rock. She went to the cabinet and selected a 100 mL graduated cylinder. She filled the graduated cylinder with 40 milliliters (mL) of water. Once she was back at her lab station, she dropped the rock into the water. She then read the new measurement and noticed it had risen to the 60 mL line. Which of the following is the volume of Marsha’s rock?

• 20 mL

• 40 mL

• 60 mL

• 100 mL

A rocket is traveling through space at a constant speed. What must be applied to the rocket in order to change its direction or speed?

• A. friction

• B. magnetism

• C. a balanced force

• D. an unbalanced force
