There you go!
as it is unnecessary to find velocity, so use the equation with v
remember to take all directions downwards as it is more convenient to calculate
after substituting the values, you have to reject the negative answed as time must be+
:)
The vertical displacement of the wave is measured from
the equilibrium to the crest and is called the amplitude.
Explanation:
In an acid solution, the concentration of H₃O⁺ ions is more than OH⁻
In a basic solution, the concentration of OH⁻ is more than that of H₃O⁺
By definition:
According to Arrhenius theory;
An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution. The hydroxonium ions formed as a result of the chemical bonding between the oxygen of water molecules and the protons released by the acid due to its ionization.
A base is a substance that interacts with water to produce excess hydroxide ions, OH⁻ in an aqueous solution. The common bases are NaOH and KOH

Answer:
Explanation:
<em>Assuming that the thermal expansion of brass cube occurs isotropically (i.e. equal in all the directions).</em>
Given:
- length of the cube,
- change in temperature of the cube,
- coefficient of volume expansion,
<u>Hence volume of the cube:</u>
Now the volume of the cube after expansion:
Therefore,
<u>Now the percentage change in the edges of the cube:</u>
Answer: Well you didn't give any answers so my guess would be it depends how much force you put into it and where you throw it.
