One factor that drives atmospheric circulation is the movement of air from warm equatorial areas to cooler areas.

The atmosphere is that thin gaseous envelope that surrounds our planet; it is not at all motionless in relation to the Earth; On the contrary, it is constantly animated by various movements.
These movements of the atmosphere have extremely variable characteristics:
- sometimes, it's a pleasant breeze that comes to refresh us, by a beautiful summer afternoon, when we are at the seaside;
- sometimes, it is violent winds which sweep a large part of France while wrapping around a vast zone of low pressures; from time to time these winds are so violent that they can uproot trees and make roofs fly away;
- and, sometimes, these movements of the atmosphere are in the form of fast ascents, with vertical speeds of the order of 10 m / s; these ancestries are localized, occurring on a small horizontal surface, of the order of a square kilometer, and they can give rise to a cloud of storm, the famous cumulonimbus.
Although this list is far from complete, it illustrates the great diversity of atmospheric movements.
so that's true

Answer:
Fr = 150 [N]
a = 5 [m/s²]
Explanation:
In order to find the resulting force, we must assume that the thrust force is positive to the right, while the friction force is negative to the left.
Now Newton's Second Law tells us that the sum of the forces or the resulting force is equal to the product of mass by acceleration.
F = m*a
Answer:
No
Explanation:
The equation of state for ideal gases tells that:
where
p is the gas pressure
V is the gas volume
n is the number of moles of the gas
R is the gas constant
T is the absolute temperature
In this problem, we have a fixed mass of gas. This means that the number of moles of the gas, , does not change; also, the volume V remains the same, and R is a constant, this means that
So, as the pressure increases, the temperature increases.
However, here we want to understand what happens to the average distance between the molecules.
We have said previously that the number of moles n does not change: and therefore, the total number of molecules in has does not change either.
If we consider one dimension only, we can say that the average distance between the molecules is
where L is the length of the container and N the number of molecules. Since the volume of the container here does not change, L does not change, and since N is constant, this means that the average distance between the molecules remains the same.
