Answer:
The answers to the question are
(a) The integer n that describes the harmonic whose frequency is 571 Hz is 5
(b) The length of the tube is 0.75 m.
B. The depth of the well is 7.12 m.
Explanation:
The nth harmonic of a tube with one end closed is given by
and the next harmonic is
Therefore ividing the first two equations by each other we have
from which n =
Therefore the interger that descries the first harmonic is
n = = 5
(b) We have the length of the pipe given by
L = 5λ/4 but λ = v/f = 343/571 = 0.6 ∴ L = 5*0.6/4 = 0.75 m
B. From n = we have
n for the 36.1 Hz frequency
n = = 3 Therefore λ = v/f = 343/36.1 = 9.5 m
L = 3*λ/4 = 3*9.5/4 = 7.12 m
The well is 7.12 m deep
We can use the relation of ohm's law to find out the resistance of wire
given that
V = 59 volts
i = 2 A
now as per above formula
So resistance of wire is 29.5 ohm.
Hi! The answer is ‘B’! Because the nucleus is found at the center and contains protons (positive charge) and neutrons (no charge)
Answer:
the outer covering of a bird is usually for camoflauge (idk how to spell) or to attract mates and the outer part of a tree is used for protection i think, correct me if im wrong ;-;
