After school, Fran rushed into the house and dropped her book bag and basketball on the carpeted floor. The basketball rolled on the carpet, but the book bag did not move from where she dropped it. Which statement explains the difference in the motion of the two objects?

• The surfaces of the objects affect the amount of friction between them and the carpet.

• The surface of the carpet affects the amount of friction between it and the objects.

• The surface of both the carpet and the objects affected the motion of the objects.

• The force that Fran used when she threw the objects onto the carpet made the difference.

A student adds 70 g of water to a beaker with a mass of 115 g. She also adds a specific amount of sugar to the beaker. She then mixes the contents in the beaker and measures the mass of the beaker on a scale. The beaker has a mass of 210 g. What is the mass of the sugar added to the beaker?

• A) 25 g

• B) 95 g

• C) 140 g

• D) 210 g

A solution contains 20 g of salt dissolved in 200 mL of water in a beaker. Which action would decrease the concentration of the solution?

• adding 50 mL of water to the solution

• adding 2 g of salt to the solution

• using a smaller beaker to hold the solution

• heating the solution to make the water evaporate

A small plastic ball is hung from the ceiling. Two boys apply a force on the ball from either side as shown in the image. How will the ball move?

• The ball will move right because the person who applies a greater force is on the left.

• The ball will move left because the person who applies a greater force is on the right.

• The ball will not move because the person who applies a greater force is on the right.

• The ball will move left because the person who applies a greater force is on the left.
