When a layer of cold air close to the ground is covered by a layer of warmer air, sound waves traveling upward may be bent, or refracted, by the difference in temperature and redirected toward the ground.
Maybe push or pull an object with a large amount of mass? you are force a (pushing through object) aka making contact. i hope i helped not good with physics :)
Answer:
The required new pressure is 775 mm hg.
Explanation:
We are given that gas has a volume of 185 ml and a pressure of 310 mm hg. The desired volume is 74.0 ml.
We have to find the required new pressure.
Let the required new pressure be '
'.
As we know that Boyle's law formula states that;
where, 
= original pressure of gas in the container = 310 mm hg
= required new pressure
= volume of gas in the container = 185 ml
= desired new volume of the gas = 74 ml
So, 
= 775 mm hg
Hence, the required new pressure is 775 mm hg.

These anisotropies in the temperature map correspond to areas of varying density fluctuations in the early universe. Eventually, gravity would draw the high-density fluctuations into even denser and more pronounced ones.
