Answer:add resistance in the parallel circuit with the total resistance
Explanation:
the total resistance in the parallel circuit is also add resistance.
<span>Carbon atom showing 6 protons as electro positive charge in its nuclei should have same no of -ve charged electrons , that is 6 electronns in its radii to make an atom of C as a neutral element , for that each element in its atomic state should have equal no of protons and electrons , the no of neutrons which has no electric charge and almost negligible weight does play significant role except contributes to isotopes of the given atom or an element, so C atom having 6 protons should have 6 electrons</span>
Given:
f1 = 20 Hz
f2 = 20000 Hz
speed of sound at 20 degrees celcius = 343 m/s
Solution:
for f1 = 20 Hz,
Using the equation:
lambda = speed of sound / f1 = 343 / 20 = 17.15 m
For f2:
lambda = speed of sound / f2 = 343 / 20000 = 0.01775 m
Therefore the wavelength range of audible sound in air would be 17.15 m to 0.01775 m.
