• put on safety goggles

• run to the nurse's office

• wipe eyes with a clean, dry cloth

Students in science class are conducting experiments causing strips of zinc to react with hydrochloric acid. Which pieces of safety equipment should each student have?

Why do most roller coasters start by slowly taking the roller coaster carts up a very tall hill?

• To maximize the kinetic energy at the beginning of the ride.

• To maximize the gravitational potential energy at the beginning of the ride.

• To equalize the gravitational potential energy at the beginning of the ride with the kinetic energy.

• This is actually a safety feature that is unrelated to the energy of the ride.

Which of the following conclusions best describes the relationship between the gravitational potential energy before the experiment and the kinetic energy of the ball after it has fallen?

• As initial potential energy increases, final kinetic energy decreases.

• As initial potential energy increases, final kinetic energy remains constant.

• As initial potential energy increases, final kinetic energy increases.

• As initial potential energy decreases, final kinetic energy increases.

Mechanical waves are waves that must have a medium to travel through. Which of the following would be classified as mechanical?

• Microwaves

• Light

• Sound

• Radio

In a concert hall, there are some places where the sound is very difficult to hear. These "dead zones" occur because:

• Architects do not want people to sit in those areas.

• Beats cause damping of the sounds.

• The sound waves have frequencies too low for humans to hear.

• Interference causes the sound waves to cancel each other out.
