The angular velocity of the stepped cylinder is determined as 2.35 rad/s.
<h3>Centripetal acceleration of the cylinder</h3>
The centripetal acceleration of the cylinder is calculated as follows;
F = ma
a = F/m
a = 40/ 36
a = 1.11 m/s²
<h3>Velocity of the cylinder</h3>
a = v²/r
v² = ar
v² = 1.11 x 0.2
v² = 0.222
v = 0.47 m/s
<h3>Angular velocity of the cylinder</h3>
v = ωr
ω = v/r
ω = 0.47/0.2
ω = 2.35 rad/s

Answer:
Explanation:
Lets see the given parameters.
Length of wire (L) = 6.93
Linear Density of wire (m/L) = 0.019 kg/m
Tension Force (F) = 365 Newtons
Now, the fundamental frequency () of the wire is given by the formula:
Where
L is length of wire
F is the tension force
m/L is the linear density
Plugging in, we get:
We can say the fundamental frequency to be about 10 Hz
Now, we know that the lowest frequency humans can hear is 20 Hz.
The lowest harmonic number is gotten by dividing this by the fundamental frequency:
20/10 = 2
Thus,
n = 2
