an ore is a naturally occurring solid material from which a metal or valuable mineral can be profitably extracted.
The statement which best explains why when you trip, your foot stops, but your body continues to move forward is: A. An unbalanced force stops your foot but does not act on the rest of your body.
A force can be defined as a push or pull of an object or a physical body, which typically results in a change of motion due to the interaction of the object with another.
In Physics, there are two (2) main types of force and these are:
An unbalanced force occurs when two or more forces acting on an object or a physical body are not equal in magnitude and as such, it typically results in a change of motion.
In conclusion, when you trip, your foot stops, but your body continues to move forward because an unbalanced force stops your foot but doesn't act on the other part of your body.

The force = 0.3 * 9.8 = 2.94
x = 0.13
k = 2.94/0.13
k = 22.6 N/m
To solve this problem we will apply the concepts related to the Force of gravity from Newtonian theory for which it is necessary to
Where,
G = Gravitational universal constant
M = Mass of Earth
m = mass of Object
x = Distance between center of mass of the objects.
From this equation we can observe that the Force is inversely proportional to the squared distance between the two objects. The greater the distance, the lower the force of gravity and vice versa.
If you want to increase the force of gravity, you need to reduce the distance of the two. Therefore the correct option is B. Talk to the distance between them.
