<h2><u>STRATOS</u><u>PHERE</u></h2>

The troposphere is heated from the ground, so temperature decreases with altitude. Because warm air rises and cool air sinks, the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV radiation.

Answer:
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. Gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Answer:
![v = 10.8 m/s^{2}](https://tex.z-dn.net/?f=v%20%3D%2010.8%20m%2Fs%5E%7B2%7D)
Explanation:
The centripetal force experienced by the steel toolbox is provided by the friction between the toolbox and the bed of the truck.
Therefore,
--------------------------------(1)
Here,
v - speed of truck
m - mass of toolbox
r - radius of curve around which the truck is turning
f - frictional force
μmg
In order to obtain Vmax, frictional force must also be max
Thus,
f = μmg--------------------------------------------------(2)
Substitute (2) in (1)
μmg
μgr
g - 9.8 m/![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
The standard value of coefficient of static friction between steel and steel is
μ ≈ 0.7
Therefore,
![v = 10.8 m/s^{2}](https://tex.z-dn.net/?f=v%20%3D%2010.8%20m%2Fs%5E%7B2%7D)
Answer:
Rolling = Riding a bicycle on a sidewalk
Static = Pushing a car unsuccessfully
Sliding = Pulling your computer across the bed
Fluid = Throwing a soccer ball to your friend
