We have given 
The plank's constant 
Mass of electron 
Now according to Heisenberg uncertainty principle 
So
The amplitude of a sound<span> wave </span>determines<span> its </span>loudness<span> or volume. A larger amplitude means a louder </span>sound<span>, and a smaller amplitude means a softer </span><span>sound</span>
