one layer of earth's atmosphere is called the stratosphere. At one point above earth's surface the stratosphere extends from an

altitude of 16 km to an altitude of 50 km. Write a compound inequality to show the altitudes that are within the range of the stratosphere. (please show work! i really need to know how to figure out these word problems. thanks!)

According to all the given requirements 

stratosphere x starts at an altitude of 16 km

that means  

<span>16≤x

</span> and,as given ,stratosphere ends at an altitude of 30 km:
which means
<span>x≤30</span> combining both of them we get

<span>16≤x≤30</span> So the range of the stratosphere is from 16 to 30 km.

Answer:

The Stratosphere layer is the layer next to the troposphere and it extends from an elevation of about 10-15 km to 50-60 km above the surface of earth. In this layer, the temperature increases with the increasing height. This increase in temperature is because of the presence of the ozone. This ozone is also called good ozone as it protects the lives on earth from the harmful ultraviolet radiations emitted from the sun.

In order to show the elevation range of the stratosphere layer, in the form of compound inequalities, we take two equations from the given data-

=> X ≥ 16 -------- (equation 1), where X= thickness of the stratosphere layer.

=> X ≤ 50 -------- (equation 2)

Now, from equation 1 and equation 2, we have,

=> 16 ≤ X ≤ 50

So, in conclusion, we can say that the thickness of stratosphere ranges from 16 to 50 km.

What does the statement "all motion is relative"<br> mean?
tekilochka [14]
The statement that motion is relative is an important concept in physics. The meaning behind this statement is that the motion of an object is relative to either the frame of reference of the observer, or to another distinct frame of reference.

How do I figure out this
ahrayia [7]
The Atomic Number is equal to the amount of Protons and Electrons. To find the amount of Neutrons in an atom, you have to look at the Mass Number. The Mass Number is the SUM (_+_=_) of Protons and Neutrons in an atom. In this case, you will have to make up equations. For example: Argon. Argon's Mass Number is 40. You need to find the amount of Protons in the atom (18). Mass Number (40) - Protons (18) = Amount of Neutrons. 40-18=22.
Argon has 22 Neutrons, because Protons(18)+Neutrons(22)=Mass Number(40).

Answer:

F3 is the equilibrant force equal in magnitude to the resultant between F1 and F2 but opposite in direction to it.

Explanation:

Given the diagram, the force F3 to make the body remain at rest or in equilibrium is the equilibrant force, this force is equal in magnitude to the resultant Fr between F1 and F2 but opposite in direction to it.

See attachment for diagram of forces.

The resultant force;

Fr =√ (F1)² + (F2)²...(1) [diagram a]

Therefore the length of F3 is Fr

F3 = -Fr

The direction (diagram b) of the resultant force Fr is given by

∆ = acrtan[(F1/F2)]

The direction of F3 is [90 + arctan(F1/F2)]

As seen in the diagram (d), the location of the force is in the fourth quadrant.
