Why is water considered to be a complex compound
2 answers:
Compounds contain two or more different elements.
Water is a molecule because it contains molecular bonds . Water is also a compound because it is made from more than one kind of element. (oxygen and hydrogen).
So If you like, you can say that water is a molecular compound.

Answer:
Water is a simple compound.
Explanation:
Water, from first glance, is a simple compound. This is because it is made up of two atoms - hydrogen and oxygen. This gives the formula:
In the simple compound, one atom of oxygen is bound to two hydrogen atoms like this:
The bonding in water is hydrogen bonding. This is a bonding that takes place between the oxygen atom and a hydrogen atom of the next water molecule.
This makes the water molecule an interesting molecule.

The tension in the string B) It quadruples.
Explanation:
The ball is in uniform circular motion in a horizontal circle, so the tension in the string is providing the centripetal force that keeps the ball in circular motion. So we can write:
where:
T is the tension in the string
m is the mass of the ball
v is the speed of the ball
r is the radius of the circle (the lenght of the string)
In this problem, we are told that the speed of the ball is doubled, so
v' = 2v
Substituting into the previous equation, we find the new tension in the string:
Therefore, the tension in the string will quadruple.
