Answer:
30.95°
Explanation:
We need to define the moment of inertia of cylinder but in terms of mass, that equation say,

Replacing the values we have,


At the same time we can calculate the mass moment of intertia of cylinder but in an axial way, that is,



Finally we need to find the required angle between the fixed line a-a (I attached an image )

Replacing the values that we have,





Some of the scientific questions that may be answered through the experiment are:
(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?
(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?
True i believe because people use this with the wrist and the neck
