The relationship between the magnitude of the force of tension and the force of friction is; Ff = (r/R)Ft
<h3>What is Rotational Acceleration?</h3>
We are given;
mass of spool = M
Radius = R
moment of inertia = I.
Now, the spool is not moving and as such;
r < R which means there is net torque = 0
Thus;
Ff × R = Ft × r
>> Ff = (r/R)Ft
Finally, the angular acceleration is expressed as;
α = a/R

Based on the standard formula and data in the question, the frequency of a sound source that produces the same wavelength in 20∘c air is "<u>115.87Hz</u>."
<h3>What is the frequency of a sound source?</h3>
The <u>frequency of a sound source</u> is the quantity of waves that move through a point per unit of time.
Typically, a sound wave arises from a source vibrating at a frequency f, propagates at v, and has a wavelength λ.
Therefore, in this case, we have
Velocity (v) of sound in air = 343 m/s
Wavelength (λ) = 2.96 m
Frequency (f) =?
f = v ÷ λ
f = 3.43m/s ÷ 2.96m
=> 115.87Hz
Hence, in this case, it is concluded that the correct answer is 115.87Hz.

You're starting with
(12.0 mL) (0.550 M) = (0.0120 L) (0.550 M) = 0.00660 mol
of FeCl₃.
For every mole of FeCl₃ in the balanced reaction, you need 3 moles of NH₄OH, so you need a minimum 0.0198 mol NH₄OH per mole FeCl₃.
Then the requisite volume of NH₄OH solution needed is <em>V</em> such that
(0.0198 mol) / <em>V</em> = 0.200 M
Solve for <em>V</em> to get
<em>V</em> = (0.0198 mol) / (0.200 M) = 0.0990 L = 99 mL
