Irina-Kira [14]

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.

An object is acted upon by a force of 22 newtons to the right and a force of 13 newtons to the left. What is the magnitude and d
Damm [24]

9 Newtons on the right, because:

Right and left are opposite directions, however, in the same direction.

We know that, opposite directions, the signal is of subtraction. So, you need to make the difference between 22 and 13, you will see that it is 9. Therefore, the Resulting Force will be 9.

What is the formula for conservation of momentum
olga55 [171]

Answer:

The general equation for conservation of momentum during a collision between n number of objects is given as: [m i ×v i a ] = [m i ×v i b ] Where m i is the mass of object i , v i a is the velocity of object i before the collision, and v i b is the velocity of object i after the collision.
