The atmosphere on Mars is composed mostly of carbon dioxide (CO2), which is a gas somewhat heavier than air (which is mostly oxygen and nitrogen). Considering this fact, describe any difference in the motion of sound waves on Mars.

• Sound waves on Mars would travel faster due to the heavier CO2 atmosphere.

• Sound waves on Mars would travel slower because CO2 is a heavier gas than Earth's air.

• There would be no difference in the motion of sound waves on Mars.

• Sound waves cannot travel on Mars due to the lack of an atmosphere.

During a music festival, Alex notices a constant buzzing sound coming from the speakers, with an intensity measured at 100 dB. Alex suggests they should stay since the music is enjoyable, but Jordan insists on moving back to avoid potential hearing damage. Whose advice is more prudent?

• Agree with Alex, because enjoying the music is more important than worrying about temporary noise.

• Agree with Jordan, because exposure to 100 dB sound can cause hearing damage over time, regardless of how enjoyable the music is.

• Agree with neither, because sound levels at music festivals are always within safe limits.

• Agree with both, because while the music is enjoyable, the sound level is not significantly harmful.
