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.

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.

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 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.

Which list correctly completes the model to represent how information from stars can be used to understand the nature of the universe?

• 1. away 2. redshifted 3. expanding

• 1. toward 2. unshifted 3. expanding

• 1. toward 2. redshifted 3. contracting

• 1. away 2. unshifted 3. contracting

In 1929 American astronomer Edwin Hubble published observations that the wavelength of light emitted from distant galaxies was long and that it shifted toward the red end of the electromagnetic spectrum. Which conclusion about these galaxies can best be made from these observations?

• The galaxies are old since their wavelengths of light are compressed.

• The galaxies are newly formed since their wavelengths of light are stretched.

• The galaxies are moving toward Earth because their wavelengths of light are compressed.

• The galaxies are moving away from Earth because their wavelengths of light are stretched.

The map shows the locations of volcanoes in an area.

Which geologic feature is most likely responsible for the formation of these volcanoes?

• a convergent boundary where oceanic crust is being subducted

• a divergent boundary where new crust is forming a mid-ocean ridge

• a region where hot convection currents are rising through the mantle

• a hot spot where crust is thin enough to allow mantle material to rise to the surface
