From about 1937 to the present, the United States has operated under a Cooperative Federalism model.
A long string can be easily stretched. The Two points on the string are labeled A and B is that A should be at 90 degrees with same magnitude and B should be at 270 degrees with same magnitude.
<h3>What is Angle magnitude</h3>
- This is known as the amount of rotation via which one of the arms is said to be rotated about vertex to result in a given position of the other.
Equal vectors are known to have the same magnitude and direction. Two vectors are said to be equal when their magnitude and direction are said to be same.

A long string is stretched and its left end is oscillated upward and downward. Two points on the string are labeled A and B.At the instant shown, orient v(A) and v(B) to correctly represent the direction of the wave velocity at points A and B.At each of the points A and B, rotate the given vector to indicate the direction of the wave velocity.Figure:A string is attached and moving up and down

Blood donation occurs when blood is drawn voluntary from an individual for transfusion.
<h3>
What is Transfusion?</h3>
This is the process of donating blood to an individual and is usually done intravenously.
Before blood donation takes place , necessary tests are usually done to prevent infection and ensure the blood types match to prevent coagulation and death.

Bromine has stronger inter molecular force than Fluorine.
<h3> Inter molecular forces and relationship with physical states of matter</h3>
The intermolecular forces of a substance tells the physical state of that substance , We can therefore say that the Solid, liquid and gas states of substances depends on the intermolecular forces surrounding them.
- For solids,the inte molecular forces will be so strong as they draw the molecules together giving them a compact structure.
- For liquids, the the inter molecular forces will be just strong enough to keep the molecules together in a confined space.
- For gases, the the inter molecular forces are weakest as the molecules move about.
We can then conclude that At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has a stronger intermoleclar force.
