Answer:
Yes
Explanation:
The rods that are supposed to control the flow of neutrons of uranium were not inserted back into their proper place when the nuclear reactor started again. This caused the reactor to overheat and explode. So, this was basically human error.
<h2>
Answer: It is the same force that causes an apple to fall to the ground.</h2>
The force that makes two galaxies to be attracted to each other is the same force that causes an apple to fall to the ground. This is known as the Gravity Force.
This force was named by Issac Newton, after some empirical observations in nature and then he published the Universal Law of Gravitation on 1687:
<em>The force
exerted between two bodies of masses
and
and separated by a distance
is equal to the product of their masses and inversely proportional to the square of the distance.</em>
Written in a mathematical form is:

Where
is the gravitational constant
So, this force between two bodies (two galaxies or an apple and the ground) is directly proportional to the product of the mass of both and inversely proportional to the square of the distance that separates both bodies.
This means the gravity force <u>decreases</u> when the distance between these two bodies <u>increases</u>.
Therefore, the correct option is a.
Sinkholes and karst topography are a clear indication that the groundwater is moving through a limestone and forming caves that periodically collapse.
