Semester 2 Review

How does the acceleration of Cart A compare to the acceleration of Cart B?

• It is twice the magnitude, but in the opposite direction of cart B’s acceleration.

• It is twice the magnitude and in the same direction as cart B’s acceleration.

• It is the same magnitude, but in the opposite direction of cart B’s acceleration.

• It is the same magnitude and in the same direction as cart B’s acceleration.

Julie was studying a chart in her science book about the density of different materials and the speed that sound waves travel. Which of the following conclusions could Julie reach using the data?

• Sound waves travel faster through cork because it floats when placed in water.

• Sound waves travel faster through steel because it sinks when placed in water.

• Sound waves travel the fastest through cork because it has the lowest density.

• Sound waves travel the fastest through steel because it has the highest density.

Which question would be the BEST to ask to determine if a wave is an EM wave or a mechanical wave?

• Does the wave contain energy?

• Does it require a medium to travel?

• Is it a longitudinal or transverse wave?

• Does the wave have a crest and trough?

A speaker produces sound waves in a column of air. The sound waves move from left to right through the air column as shown in the diagram. Using information from the diagram, what is happening to the gas particles as the sound waves move? Explain.

• The sound wave produces compressions in the air where the air particles are close together because the air pressure is lower in these regions.

• The sound wave pushes the air particles along the column of air as it moves from left to right because the sound wave takes up space.

• The sound waves produce compressions and rarefactions in the column of air. The compressions move through the air particles, but the air particles do not move with the sound wave.

• The sound wave produces compressions and rarefactions in the column of air. In compressions, the air particles are close together. The compressed air particles move with the sound wave.

Two waves are depicted on the graph. The first wave is marked by points A, B, C, D, E, and F. The second wave is marked by points m, n, p, q, r and s. Compare the two waves shown in the graph. How are they similar, and how are they different?

• The two waves have the same energy, but have different frequencies.

• The two waves have the same energy, but have different amplitudes.

• The two waves have the same period, but have different frequencies.

• The two waves have the same period, but have different wavelengths.
