Answer:
The correct answer to the question is
B. It always decreases
Explanation:
To solve the question, we note that the foce of gravity is given by
where
G= Gravitational constant
m₁ = mass of first object
m₂ = mass of second object
r = the distance between both objects
If the mass of one object remains unchanged while the distance to the second object and the second object’s mass are both doubled, we have
= 
Therefore the gravitational force is halved. That is it will always decrease
A because an earthquake is shaking of tectonic plates
Answer:
D. O2 is removed from the atmosphere, and CO2 is released

Answer:

Explanation:
From this exercise, our knowable variables are <u>hight and initial velocity </u>


To find how much time does the <u>ball strike the ground</u>, we need to know that the final position of the ball is y=0ft


Solving for t using quadratic formula


or 
<u><em>Since time can't be negative the answer is t=6.96s</em></u>
