Answer:
The answer will be listed below.
Explanation:
Kinetic Energy- Energy of motion, increases with mass
Potential Energy- Stored energy, increases with height
Both- Increases with velocity
The diameter of the pool is 4
Explanation:
To calculate the diameter we must write the values given in the question, here
The circumference of the pool is given as C=12.56 feet.
To calculate the diameter of the pool,
If radius is given, Multiply the radius by 2
If Circumference is given divide the circumference by Pi (π)
the constant value for Pi (π)=3.14
Diameter(D)= C/π
12.56/3.14
=4
The diameter for the plastic wading pool is 4
Answer : Cadmium sulfide (CdS) precipitate is formed.
Explanation :
When the sodium sulfide, 
is mixed with cadmium sulfate, 
then cadmium sulfide precipitate and sodium sulfate, 
is formed. The cadmium sulfide is insoluble in hot and cold water but sodium sulfate is soluble in water.
The balanced chemical reaction will be,
This reaction is an example of double displacement reaction in which the cation and anion of the two reactants exchange their places to give two new products.
This is a chemical reaction where the two clear solutions mixed to produce a bright yellow colored precipitate of cadmium sulfide.
