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

D. where is liquid water found in our solar system I think is the correct answer
The mole fraction of the non-volatile solute in the solution is 0.13.
<h3>Mole fraction of solute </h3>
Using law of vapor pressure formula
Mole fraction of the non-volatile solute=Vapor pressure of the pure acetone-Vapor pressure of the solution /Vapor pressure of the pure acetone
Where:
Vapor pressure of the pure solvent (acetone) =266 torr
Vapor pressure of the solution =232torr
Mole fraction of solute = ?
Let plug in the formula
Mole fraction of the non-volatile solute=266-232/266
Mole fraction of the non-volatile solute=34/266
Mole fraction of the non-volatile solute=0.127
Mole fraction of the non-volatile solute=0.13 (Approximately)
Inconclusion the mole fraction of the non-volatile solute in the solution is 0.13.
