There
are five layers of the atmosphere and these are; troposphere, stratosphere,
mesosphere, thermosphere and exosphere. The first layer, troposphere, is where
we are able to do most of our activities. This is where we can see the formation
of clouds, the production of rain, hail, snow and other weather phenomenon.
Also, this layer is where the greatest amount of air pressure because most of
the molecules of air are in this area. Like us, air has also mass and the
pressure is brought down by the earth’s gravity causing an increase in weight
exerted on you as you descend lower into the atmosphere. So, as you enter into
the other layers of atmosphere above the troposphere, the air pressure starts
to decrease. <span>Below the atmosphere
is the hydrosphere. This is where all liquid forms are located. And since the
seawater has a greater mass than air, it has the greatest pressure. </span>
Answer:
Explanation:
ASSUMING that the cab has ONLY kinetic energy,
(it's not sitting over a loaded spring, high on a hill, on fire)
KE = ½mv²
v = √(2KE/m)
v = √(2(18750)/2100) = √17.85714...
v = 4.225771...
v = 4.23 m/s or about 15.2 km/hr
