Students are using a hand-held generator to produce light energy.  Which of the following statements are true? (Choose 2)

• Turning the handle at different speeds would change the brightness of the bulb

• Painting the light bulb to change its color would change the amount of energy that flows into the bulb.

• Putting an adapter with another bulb would cause both bulbs to burn brighter because they can use the same electrical energy.

• Turning the handle proves that electrical energy flows in a circular motion.

• Replacing the bulb with a buzzer would cause the electrical energy to be transformed into sound energy.

Josephine collected a bucket of seawater from her local beach. She wanted to determine the amount of salt that was dissolved in the ocean water. Which would be the best way for Josephine to separate the salt from the water?

• Stir the water for a long time. The salt will come together as a large crystal.

• Leave the seawater out in the sun for a long time, the water will evaporate.

• Leave the seawater in a dark cool place, the salt will sink to the bottom.

• Freeze the seawater, the salt will float to the top.
