Answer:
Explanation:
We'll use the momentum equation:
where:
p = momentum
m = mass
v = velocity
Since we're doing the magnitude of momentum of the system, we'll add the mass of the cyclist and the mountain bike together:
Given that, we can now substitute our given values into the momentum equation:
Our final answer is:
Answer:
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.
Answer:
<h2>Focal length</h2>
Explanation:
The Focal length of a lens is the distance from the center of the lens to
its principal focus.
Brushes, battery terminals, commutator, armature, magnets
There must be a centripetal force to move the object move in a curve path.
