C I’m not that sure though
Answer:
the awnser is momentum i did this before
Explanation:
Answer:
See the attached image and the explanation below
Explanation:
We must draw a schematic of the described problem, after the sketch it is necessary to make a free body diagram, at the time before and after cutting the cord.
These free body diagrams can be seen in the attached image.
First we perform a sum of forces on the x & y axes before cutting the cord, to be able to find the T tension of the wire. (This analysis can be seen in the attached image).
In this way we get the T-wire tension equation, before cutting.
Now we make another free body diagram, for the moment when the wire is cut (see in the attached diagram).
It is important to clarify that when the cord is cut, the system will no longer be in statically, therefore newton's second law will be used for summation of forces which will be equal to the product of mass by acceleration.
Finally with equations 1 and 2 we can find the K ratio.
Answer:
Volcanic lightning is created when a volcano erupts and lots of tiny fine particles of volcanic ash form a cloud. Friction between the particles of ash and the gases emitted from the eruption cause differentces that create lightning. Friction between the particles of ash and the gases emitted from the eruption cause differentces that create lightning. The lightning usually occurs between clouds and from the eruption column to the crater.

Answer:
D) ¼ as large
Explanation:
The magnitude of the electric force between two charges is
where
k is the Coulomb's constant
q1 and q2 are the magnitudes of the two charges
r is the separation between them
From the formula we see that the magnitude of the force is inversely proportional to the square of the distance.
In this problem, the distance is doubled:
So the new force will be
So the force will decrease to 1/4 of its original value.
