Answer:
We can solve this by analyzing the choices and the relations between variables.
Notice that Kinetic Energy depends on the speed and the mass. Actually the Kinetic Energy is directly proportional to those variables, which means the more mass or the more speed, the more Kinetic Energy would be.
Having said that, Part I and Part II must have speed and mass as independent variable, because Kinetic Energy depends on them.
Then, in the third question, the answer is Kinetic Energy because that's the dependent variable in both cases Part I and Part II.
Just to remember, the Kinetic Energy is defined as
Where you can notice the relation between mass, speed and kinetic energy.
Therefore, the right answer are Mass (Part I), Speed (Part II) and Kinetic Energy (Part III).

Answer:
The frictional torque is ![\tau = 0.2505 \ N \cdot m](https://tex.z-dn.net/?f=%5Ctau%20%20%3D%200.2505%20%5C%20N%20%5Ccdot%20m)
Explanation:
From the question we are told that
The mass attached to one end the string is ![m_1 = 0.341 \ kg](https://tex.z-dn.net/?f=m_1%20%3D%20%200.341%20%5C%20kg)
The mass attached to the other end of the string is ![m_2 = 0.625 \ kg](https://tex.z-dn.net/?f=m_2%20%3D%20%200.625%20%5C%20kg)
The radius of the disk is ![r = 9.00 \ cm = 0.09 \ m](https://tex.z-dn.net/?f=r%20%3D%209.00%20%5C%20cm%20%20%3D%200.09%20%5C%20m)
At equilibrium the tension on the string due to the first mass is mathematically represented as
![T_1 = m_1 * g](https://tex.z-dn.net/?f=T_1%20%3D%20%20m_1%20%2A%20%20g)
substituting values
![T_1 = 0.341 * 9.8](https://tex.z-dn.net/?f=T_1%20%3D%20%200.341%20%2A%209.8)
![T_1 = 3.342 \ N](https://tex.z-dn.net/?f=T_1%20%3D%20%203.342%20%5C%20N)
At equilibrium the tension on the string due to the mass is mathematically represented as
![T_2 = m_2 * g](https://tex.z-dn.net/?f=T_2%20%3D%20%20m_2%20%2A%20%20g)
![T_2 = 0.625 * 9.8](https://tex.z-dn.net/?f=T_2%20%3D%200.625%20%2A%209.8)
![T_2 = 6.125 \ N](https://tex.z-dn.net/?f=T_2%20%3D%206.125%20%5C%20N)
The frictional torque that must be exerted is mathematically represented as
![\tau = (T_2 * r ) - (T_1 * r )](https://tex.z-dn.net/?f=%5Ctau%20%20%3D%20%20%28T_2%20%2A%20r%20%29%20-%20%28T_1%20%2A%20r%20%29)
substituting values
![\tau = ( 6.125 * 0.09 ) - (3.342 * 0.09 )](https://tex.z-dn.net/?f=%5Ctau%20%20%3D%20%20%28%206.125%20%2A%200.09%20%29%20-%20%283.342%20%20%2A%200.09%20%29)
![\tau = 0.2505 \ N \cdot m](https://tex.z-dn.net/?f=%5Ctau%20%20%3D%200.2505%20%5C%20N%20%5Ccdot%20m)
