Which statement describes the most likely outcome of an interaction between these two sound waves?

• The interaction will result in no sound.

• The interaction will result in destructive interference.

• The interaction will result in half the amount of sound.

• The interaction will result in constructive interference.

A student builds a stack of different layers of clay and places two marbles in one of the layers of clay.

Using this model, which concept can the student best communicate about the marbles?

• The marbles represent organisms of the same species that died.

• The marbles represent different fossils that are about the same age.

• The marbles represent organisms that became extinct at different times.

• The marbles represent rocks that became fossils at about the same time.

The drawing shows a bicycle that a student uses to travel every day.

The student wants to be able to increase the speed of the bike while applying the same amount of force. Which statement describes the best long-term solution to this problem?

• Switch to thinner tires to increase friction.

• Remove unneeded bike parts to reduce mass.

• Add links to increase the length of the bike chain.

• Increase the width of the tires to grip the road better

The graph shows the orbital speed of the eight planets in the solar system.

Which explanation about the orbital speed of the planets is best supported by these data?

• The orbital speed of large planets is greater than the orbital speed of small planets.

• The orbital speed of gaseous planets is greater than the orbital speed of rocky planets.

• The orbital speed of the outer planets is greater than the orbital speed of the inner planets.

• The orbital speed of the inner planets is greater than the orbital speed of the outer planets.

The magnitude of an earthquake can be measured using data from seismographs and the Richter scale. The Richter scale uses numbers 0 to 9; the larger the number, the stronger the earthquake. The graph shows 40 years of earthquake magnitude data for earthquakes of magnitude 5.0 and greater.

Which statement can a student use to explain the information shown in the graph?

• Lower-magnitude earthquakes are more likely to occur than higher-magnitude earthquakes.

• Higher-magnitude earthquakes are more likely to occur than lower-magnitude earthquakes.

• The past 40 years of data show that magnitude 6 earthquakes are common to all regions of the Earth.

• Over the next 40 years there are likely to be more magnitude 5 earthquakes than earthquakes of any other magnitude.

A student wants to perform an investigation to demonstrate how varying the amount of force affects the speed of a cart on a level surface. Which investigation plan would best demonstrate the relationship between force and speed?

• Plan: Apply an increasing amount of force to the cart over time.

  Results: The speed of the cart increases over time.

• Plan: Push the cart with a constant force over time.

  Results: The speed of the cart decreases over time due to friction.

• Plan: Apply a decreasing amount of force to the cart over time.

  Results: The speed of the cart decreases over time, then increases

• Plan: Provide an initial force on the cart followed by no additional force.

  Results: The speed of the cart remains constant due to inertia.

A student observed a white light bulb while looking through three different sheets of transparent plastic. The student recorded the observations in the data table.

Which explanation do these data best support?

• Each plastic sheet absorbs one wavelength of light.

• Each plastic sheet transmits a different wavelength of light.

• Each plastic sheet refracts the wavelengths of light from the light bulb at different angles.

• Each plastic sheet changes the wavelengths of light from the light bulb in different amounts.

One advantage of AM radio is that, since it operates at a lower frequency, it has longer wavelengths than FM radio. Longer wavelengths travel greater distances from the radio station and even through solid objects such as mountains. However, a disadvantage is that AM signals are more easily interfered with than FM signals, so the audio quality is decreased.

Which statement identifies an advantage of one of the two types of transmitted radio waves?

• Radios in areas with mountains receive type 2 radio waves better than type 1 radio waves.

• Radios in areas with mountains receive type 1 radio waves better than type 2 radio waves.

• Radios that receive type 1 radio waves have less interference than radios that receive type 2 radio waves.

• Radios that receive type 2 radio waves have more interference than radios that receive type 1 radio waves.
