Answer:
A. The sound wave will reflect off Buildings and automobiles.
Explanation:
This is because the sound waves would more likely propagate through diffraction through buildings and transmission through the air. It is also more likely to be absorbed by buildings than for multiple reflections to occur off buildings and automobiles. In the process of reflection, these materials would absorb the sound energy thereby reducing its ability to reflect.

Answer:
c. The less massive object will have less momentum if the velocities are the same.
Explanation:
p = mv
If the velocities are the same, p ∝ m, so the less massive object will have less momentum.
a. is wrong. If the masses are equal, p ∝ v, so the object with the higher velocity will have the greater momentum.
b. is wrong. If an object has both more mass and a greater velocity, it will have the greater momentum.
d. is wrong. If the velocities are the same, the more massive object will have more momentum.
Earth's atmosphere is made up of a combination of gases. The major components of nitrogen, oxygen, and argon remain constant over time and space, while trace components like CO2 and water vapor vary considerably over both space and time.
