Explanation :

The amplitude, wavelength and time period of three waves are given.

We know that energy of a wave is given by :

E=\dfrac{h\ c}{\lambda}

It is clear that energy of a wave is inversely proportional to the wavelength i.e E\propto \dfrac{1}{\lambda}

So, the wave having less wavelength will have the greatest energy.

Also, we know that energy of a wave is directly proportional to the square of amplitude i.e. E\propto(Amplitude)^2

So, again the wave having maximum amplitude will have maximum energy.

Hence, the correct option is (C) i.e. "amplitude = 14 cm; wavelength = 7 cm; period = 12 seconds".

The equation for the energy of a wave is given by the equation of E = A^2 where E is the energy of the wave and A is the amplitude. The higher the amplitude, the greater the energy of the wave is and vice versa. An amplitude of 14cm has the greatest energy of the wave followed by 12cm and then 7cm.

What is formed in the neutralization reaction between a strong acid and a strong base? (2 points)
Alborosie

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

Explain how the concentration of hydronium ions and hydroxide ions are related to pH.
Dominik [7]
Hello!

The concentration of hydronium ions is related to pH by the following simple equation:

pH=-log[H_3O^{+}]

From this equation, you can see that as the hydronium concentration is higher, the pH will be lower.

The concentration of the OH⁻ ions is related to the pH by the following set of equations

pOH=-log[OH^{-}] \\ pH=14-pOH

You can see that as the concentration of OH⁻ is higher, the pOH is lower and thus the pH is higher. 

When the pH of the solution is less than 7, the solution is acidic.

When the pH of the solution is higher than 7, the solution is basic.

Have a nice day!
