B. an inverse relationship
Explanation:
Here is the complete question
Ricardo is on vacation, doing some mountain climbing. He notices that the higher he goes up a mountain, the colder he feels. He remembers his physics teacher teaching about these types of relationships. What is the type of relationship between mountain elevation and temperature? A. a positive relationship B. an inverse relationship C. a neutral relationship D. a direct relationship
Solution
It is an inverse relationship because, as Ricardo's mountain elevation increases, he feels colder. So, as his mountain elevation increases, the temperature decreases.
Since one variable decreases while the other increases, it can only be an inverse relationship.
Let h be Ricardo's mountain elevation and T his temperature. So by inverse proportionality,
h ∝ 1/T
h = k/T
hT = k = constant
So, we have an inverse relationship and B is the answer.
Commercial airliners encounter very little turbulence above 25,000 feet because the air is so thin at altitudes above 25,000 feet that turbulence has much less effect. That is option A.
<h3>What is turbulence?</h3>
A turbulence is a sudden disturbance that an airline encounters when it hits a strong wind current that can push or pull the plane.
The depth at which the airline flies determines whether the turbulence will have little or more effects on it.
At altitudes above 25,000 feet the air is so thin and light than below 25,000 feet therefore, the airline will encounter little turbulence effect.
