Warm air aloft is normally higher pressure relative to colder air aloft, which is normally of lower pressure (at equivalent altitudes). (hint: think of columns of cold and warmer air standing side-by-side)a. trueb. false

the statement given is False.

Explanation:

The pressure is defined by

     P = F / A

The force of the air is its weight,

     P = W_air / A

The weight of an air column on us depends on the energy of the molecules that is related to the temperature

      E = 3/2 K T

 When the air is warmer it has more energy so the molecules can move more distance and therefore the average density of the gas decreases, as the density decreases, the weight of the column on us also decreases, therefore the pressure low.

The correct statement is: When the air is hotter it has less pressure than when the air is cold.

 It is summary the statement given is False

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
