What is the difference between a conductor and an insulator?

A conductor transmits energy very well while an insulator does not.

Wood is a good conductor but not a good insulator.

Metal is a good insulator but not a good conductor.

An insulator transmits energy very well while a conductor does not.

What energy transformations take place when a hair dryer is used?

Electrical energy from the circuit is transformed to thermal energy and sound energy.

Energy from the sun is transformed to chemical energy.

Electrical energy from the circuit is transformed to electromagnetic energy.

Electromagnetic energy from the circuit is transformed to thermal energy and sound energy.

A tennis ball falls off a shelf and bounces several times. Each bounce is lower than the one before. Soon the ball stops. Why doesn’t the ball keep bouncing?

Energy is transferred to the air and ground.

The energy becomes stored in the ball.

Some of the energy is changed into mass.

The air and ground slowly destroy the ball’s energy.

An ice cube is placed in a glass of warm tea. Later, the ice has melted, and the tea is cooler. What is true about the system now?

Thermal energy has been transferred from the tea to the surrounding air and glass.

Thermal energy has been transferred from the ice cube to the warm tea.

Chemical potential energy of the ice cube has been transferred to the warm tea.

Chemical potential energy of the warm tea has been transferred to the surrounding air and glass.

The speed of a mechanical wave depends on the type of medium through which it travels. Which statement is true?

Mechanical waves require a medium, but electromagnetic waves do not.

All waves travel at the same speed through any medium.

All waves travel at the same speed if no medium is present.

Electromagnetic waves require a medium, but mechanical waves do not.

The graph below shows the energy that a ball has. The ball is falling toward the ground. How will the energies change?

The gravitational potential energy will decrease, and the kinetic energy will increase.

The gravitational potential energy will decrease, and the kinetic energy will decrease

The gravitational potential energy will increase, and the kinetic energy will decrease.

The gravitational potential energy will decrease, and the kinetic energy will remain constant.

The following diagram shows a circuit. What kind of circuit is this and why?

This is a parallel circuit because the circuit splits into different branches.

This is a series circuit because all of the parts are connected by wire.

This is a closed circuit because all of the parts are connected by wire.

This is a series circuit because the circuit splits into different branches.

The following circuit contains six light bulbs, labeled A, B, C, D, E, and F. If bulb A breaks, which other bulbs in the circuit will no longer light up?

This is a parallel circuit because the circuit splits into different branches.

This is a series circuit because all of the parts are connected by wire.

This is a closed circuit because all of the parts are connected by wire.

This is a series circuit because the circuit splits into different branches.

Through which medium do sound waves travel the SLOWEST?

travel at the same speed through all materials
