Answer:
None of these is correct.
Explanation:
The wave particle duality has to do with Louis de Broglie's proposition that matter could exist as waves or particles.
According to him, matter poseses an associated wavelength. Hence, a certain wavelength is traceable to the hydrogen atom.
This wavelength is the ratio of Plank's constant to the momentum of the hydrogen atom
The answer to this problem is the results of the point A
Answer:
a) 199.04 ohms
b) attached in image
c) -0.696dB
Explanation:
We are given:
Fc = 8Khz = 8000hz

a)Using the formula:



R = 199.04 ohms
b) diagram is attached
c) 

At F = 20KHz and Fc= 8KHz we have:


=0.923
|H(F)| in dB = 20log |H(F)|
=20log0.923
= -0.696dB
