3.A simple circuit with a battery connected to a buzzer by electrical wires is placed on a table. When the buzzer sounds, it lights up and the table begins to rattle. Which form of energy directly makes the table rattle?

• chemical energy

• electrical energy

• mechanical energy

• light energy

Elaina has four objects with different masses lined up on the lab desk. She places a fan 25 centimeters (cm) away from all of the objects, turns the fan on for 10 seconds, and observed the objects. The following table shows the data she records.

• Nine grams is the maximum mass that the fan can push.

• Four grams is the maximum mass that the fan can push.

• Three grams is the maximum mass that the fan can push.

• Twelve to thirteen grams is the maximum mass that the fan can push.

Jennifer is getting ready for school on a cold day in February. She wants to make sure her hair is completely dry before she leaves her house. She plugs her hair dryer into the wall outlet and turns it on. Which of the following describes one of the steps involved in using energy to dry Jennifer's hair?

• Thermal energy is changed into mechanical energy, which makes the motor in the hair dryer move.

• Electrical energy is changed into heat energy, which makes the motor in the hair dryer move.

• Mechanical energy is changed into heat energy, which makes the motor in the hair dryer move.

• Electrical energy is changed into mechanical energy, which makes the motor in the hair dryer move.

When a radio is turned on, what energy transformation occurs?

• Heat energy is changed to light energy.

• Kinetic energy is changed to sound energy.

• Electrical energy is changed to sound energy.

• Chemical energy is changed to mechanical energy.

12.What purpose do batteries have in an electrical circuit?

• They absorb the thermal energy.

• They store light energy for later use.

• They convert chemical energy to electrical energy.

• They convert solar energy to usable kinetic energy.

When people want to use water to create electricity they generally build a dam to hold the water back, creating a large lake behind the dam. Why is it necessary to hold the water back with a dam in order to produce electricity?

• It increases the amount of water available.

• It increases the force with which the water flows.

• It forces the water to flow in the desired direction.

• It makes the water still enough to create electricity.

How does the picture relate to the particles in a solid?

• The cars are driving fast and switching lanes like the particles in a solid.

• The cars are sliding past each other while driving the speed limit like the particles in a solid.

• The cars are moving so fast you cannot even see them like the particles in a solid.

• The cars are barely moving like the particles in a solid.
